30mm² Thw Green Copper Cable - 600V

Cross-sectional Size: The 30mm² cross-sectional size is one of the core parameters of the cable. This size is determined based on an in-depth analysis of the power demand of high-power equipment. The large cross-sectional area provides a strong current-carrying foundation for the cable, enabling it to stably transmit power under high-load conditions and avoiding cable overheating due to insufficient cross-section. Compared with small cross-sectional cables, the 30mm² cable is more robust in appearance with a significantly larger outer diameter. Users can easily identify its specification through visual observation, facilitating accurate selection according to equipment power in practical applications.

Rated Voltage: The rated voltage is 600V, which makes it suitable for medium and low-voltage distribution systems. The 600V voltage level can meet the power supply needs of scenarios such as industrial production line main circuits, building main power distribution, and outdoor large temporary equipment, and is well compatible with many medium and low-voltage electrical equipment and distribution systems. In practical applications, the cable can work stably in a voltage environment of 600V and below, ensuring the safety and continuity of power transmission.

Current-carrying Capacity: At an ambient temperature of 30℃, the current-carrying capacity of the cable can reach 100-130A. This strong current-carrying capacity enables it to provide continuous and stable power for high-power equipment such as large industrial motors, central air conditioning hosts, and high-pressure water pumps. The current-carrying capacity is affected by factors such as ambient temperature and laying methods. When the ambient temperature rises, the heat dissipation performance of the cable decreases, and the current-carrying capacity will decrease accordingly. For example, at 40℃, the current-carrying capacity may drop to 90-110A; when using pipe laying or multiple cables laid in parallel, due to poor heat dissipation conditions, the current-carrying capacity also needs to be appropriately reduced to ensure the cable operates within a safe range.

Insulation Performance Parameters: The insulation resistance of the cable is ≥100MΩ·km, which ensures that the cable has excellent insulation performance, can effectively prevent current leakage, and reduce power loss. At the same time, the cable has passed the 2500V voltage withstand test, with no breakdown occurring during the 1-minute test, fully verifying its insulation stability in high-voltage environments, and providing a strong guarantee for preventing electric leakage and short-circuit accidents.

Temperature Resistance Performance: The insulation layer is made of temperature-resistant PVC material, with an operating temperature range of -15℃ to 90℃. In low-temperature environments, the cable will not become brittle and crack due to cold, still maintaining good Flexibility; in high-temperature environments, the insulation layer will not soften and deform, ensuring that the insulation performance is not affected. This wide temperature range of temperature resistance enables the cable to adapt to different climate regions and complex working environments.

Specific Identification Uses:

Conductor Material: The conductor is made of high-purity electrolytic copper with a purity of more than 99.95%. High-purity copper has extremely low resistivity, which can reduce energy loss during current transmission and improve power transmission efficiency. Electrolytic copper has been refined to remove impurities and oxides, making the conductive performance of the conductor more stable. The conductor adopts a single-strand or multi-strand stranded design. The single-strand design has high mechanical strength and is suitable for fixed laying scenarios where bending is not easy; the multi-strand stranded design takes into account both conductive efficiency and flexibility, making the cable easier to bend and lay in complex wiring environments, and can reduce conductor fatigue caused by equipment vibration, extending the service life of the cable.

Insulation Layer Material: The insulation layer is made of temperature-resistant PVC material, which has a variety of excellent properties. In addition to good insulation performance, it also has moisture resistance, and will not reduce insulation performance due to moisture in humid environments, making it suitable for use in underground, humid workshops and other environments. Its chemical corrosion resistance can resist the erosion of mild oil, acid mist and other chemical substances, protecting the conductor from damage. In addition, the flame retardant grade of the insulation layer reaches UL94 V-0 standard. When encountering an open flame, it can self-extinguish quickly without generating a large amount of toxic smoke, reducing the risk of fire spread and ensuring the safety of personnel and property.

Outer Sheath Material and Color: The outer sheath of the cable is made of green weather-resistant material. In addition to being a functional identifier, it also has excellent UV aging resistance. When used outdoors for a long time, it can resist the irradiation of sunlight and ultraviolet rays, will not crack or fade due to aging, and extend the service life of the cable. The green color identification is clear and clear, in line with international general ground wire or specific circuit identification standards, facilitating quick identification during installation and maintenance and reducing the risk of misoperation.

Style: The cable has an overall circular structure, which has many advantages. The circular structure makes the thickness of the insulation layer and outer sheath of the cable uniform, and the physical properties and insulation properties in all directions are consistent, avoiding local weak links caused by irregular shapes. During laying, circular cables are easier to be piped, 桥架 laid and directly buried, can adapt to different installation methods, and improve construction efficiency. At the same time, the circular style is also convenient for cable winding and storage, saving storage space.

Copper Smelting and Purification: First, high-quality copper ore or scrap copper is selected as raw material for smelting. During the smelting process, impurities such as iron, lead, zinc, etc. in copper are removed by adding refining agents and other processes, so that the purity of copper reaches more than 99.95%. High-purity copper is the key to ensuring the conductive performance of the cable. This step requires precise control of temperature and time to ensure the purification effect.

Precision Wire Drawing: The purified copper material is heated to an appropriate temperature, and drawn into Copper Wires with a diameter meeting the requirements through a wire drawing machine for multiple times. During the wire drawing process, it is necessary to strictly control the drawing speed, die size and cooling method to ensure that the diameter of the copper wire is uniform, the surface is smooth, and there are no cracks, scratches and other defects. For multi-strand Stranded Conductors, it is also necessary to draw multiple copper wires into the same diameter to prepare for the subsequent stranding process.

Multi-layer Stranding: For multi-strand Stranded Conductors, the concentric layer stranding process is adopted. Multiple copper wires are stranded layer by layer according to certain rules, and the stranding direction of each layer is opposite to offset the stress generated during the stranding process, improving the structural stability and flexibility of the conductor. During the stranding process, it is necessary to accurately control the tension and stranding pitch of each layer of copper wires to ensure the roundness of the conductor and the accuracy of the cross-sectional area.

Insulation Layer Extrusion: A high-temperature extrusion process is used to wrap the temperature-resistant PVC Insulation layer outside the conductor. First, the PVC particle raw material is dried to remove moisture to prevent bubbles in the insulation layer. Then, the dried PVC particles are put into the extruder for heating and melting, and the molten PVC material is evenly wrapped on the surface of the conductor through the extrusion die. During the extrusion process, the extrusion temperature (usually 160-190℃), speed and pressure are strictly controlled to ensure that the thickness of the insulation layer is uniform (1.2-1.8mm), closely combined with the conductor, and free of bubbles, wrinkles, depressions and other defects.

Outer Sheath Extrusion: A green outer sheath is wrapped around the insulation layer through an extrusion process. The outer sheath material is also strictly selected to ensure that it has weather resistance, UV aging resistance and other properties. The extrusion process is similar to the insulation layer extrusion, and it is necessary to control the temperature, speed and pressure to make the outer sheath evenly wrap on the insulation layer, closely combined with the insulation layer, and ensure that the color of the outer sheath is uniform and the identification is clear.

Cooling and Solidification: After extruding the insulation layer and outer sheath, the cable immediately enters the cooling water tank for cooling, so that the PVC material is quickly solidified and formed. The cooling water temperature needs to be strictly controlled, usually between 20-30℃, to ensure the dimensional stability and performance of the cable. During the cooling process, it is necessary to avoid material cracking caused by sudden temperature changes.

Quality Inspection: Each batch of cables undergoes multiple strict quality inspection procedures during production. Including conductor resistance test, insulation resistance test, voltage withstand strength test, insulation layer and outer sheath thickness measurement, temperature resistance test, bending resistance test, flame retardant performance test and more than 30 other index tests. Only products that meet international standards such as ANSI/UL 44 can leave the factory to ensure the quality reliability of the products.

Printing Identification: The outer sheath surface of the cable is printed with product model, specification (30mm²), rated voltage (600V), manufacturer, production date, execution standard and other information. Printing uses special printing equipment and wear-resistant ink to ensure that the handwriting is clear, firm and not easy to fall off, which is convenient for users to identify and trace product information.

Packaging Materials: Due to the large cross-section and heavy weight of the cable, wooden reels are usually used as the main packaging material. The wooden reel has high strength and stability, can bear the weight of the cable, and prevent deformation due to extrusion during transportation and storage. The wood of the reel is dried to avoid mold and deterioration due to moisture, which affects the service life. At the same time, the edge of the reel is equipped with metal edge protection to enhance the anti-collision ability of the reel. After the cable is wound on the reel, the outer layer will be wrapped with a moisture-proof and wear-resistant plastic film to prevent the cable from being damaged by dust, moisture and machinery.

Packaging Method: First, the cable is neatly wound on the wooden reel. During the winding process, the tension is strictly controlled to ensure that the cable is arranged tightly and neatly without distortion or overlap. The winding length is determined according to customer needs and industry practices, usually 100 meters, 200 meters, 500 meters and other specifications. After winding, the reel and cable are wrapped with plastic film as a whole to ensure good sealing. Then, a label is fixed on the wooden reel, indicating the product model, specification, length, production date, batch number, manufacturer and other information. For export products, corresponding marks and text descriptions will be added to the outer packaging according to the requirements of the destination country.

Packaging Marks: The marks on the packaging are clear and standardized. In addition to the basic information of the product, they also include some important warning marks, such as "Do not press heavily", "Moisture-proof and sun-proof", "Keep away from fire", "Handle with care", etc. These marks can remind transportation, storage and use personnel to pay attention to relevant matters to avoid damage to the cable due to improper operation. In addition, the marks will also indicate the implementation standards and quality certification marks of the product, highlighting the quality reliability of the product.

Transportation Methods: According to the customer's geographical location, order quantity and delivery deadline, select the appropriate transportation method. For domestic short-distance transportation (such as within a radius of 500 kilometers), road transportation is usually adopted, using large trucks (such as semi-trailers) for transportation. Road transportation has the advantages of high flexibility and being able to reach the destination directly, and is suitable for small batches and urgent orders. For long-distance transportation or large-volume orders, railway transportation is a more ideal choice. It is transported through railway freight cars, which has the characteristics of large transportation volume, relatively low cost and good stability. For export orders, sea or air transportation can be used. Sea transportation is suitable for large quantities of goods, transported through containers, with low cost but long transportation time; air transportation is fast, suitable for urgent export orders, and can quickly deliver products to customers.

Transportation Precautions:

Transportation Tracking: The company has established a complete transportation tracking system.
