Cyky Cyky-O Cyky-J Cables 3X2.5 Cu PVC Copper Insulated Power Cable

Conductor Material: The conductors of Cyky series cables use high-purity electrolytic copper with a purity of more than 99.9%. High-purity copper has excellent conductivity and high conductivity, which can reduce energy loss during current transmission and improve power transmission efficiency. At the same time, Copper Conductors also have good ductility and Flexibility, which are not easy to break during cable processing and laying, and are easy to bend and shape. In addition, copper has good chemical stability and is not easy to be corroded, which can ensure the long-term stable operation of the cable.

Insulation Material: The insulation layer of this series of cables uses polyvinyl chloride (PVC) material. PVC is a commonly used insulation material with good electrical insulation performance, which can effectively isolate current and prevent leakage accidents. It also has a certain mechanical strength, which can protect the conductor from external mechanical damage. At the same time, PVC material has good chemical corrosion resistance, which can resist the erosion of some common chemical substances and prolong the service life of the cable. However, PVC materials will release harmful gases at high temperatures, so attention should be paid to avoiding long-term exposure to high-temperature environments during use.

Style Design: The Cyky series cables are designed with 3 cores. The 3 copper cores are twisted together and wrapped with a PVC Insulation layer. This twisted structure can reduce the uneven force during cable laying and improve the mechanical strength of the cable. The color of the cable is usually black or gray, which are not only resistant to dirt but also can blend with the surrounding environment to maintain beauty. On the surface of the cable, clear information such as model, specification, and rated voltage is printed, which is convenient for users to identify and use. Cables of different models also have slight differences in appearance. The surface of the Cyky-O model is relatively smooth, while the Cyky-J model may have some special marks or textures to distinguish different uses and laying methods.

Conductor Manufacturing: First, high-purity electrolytic copper ingots are smelted, and then made into copper rods through continuous casting process. The copper rod is drawn by a wire drawing machine into a Copper Wire with a diameter of 1.78mm. Subsequently, multiple copper wires are twisted in a certain way to form a 2.5mm² conductor. During the stranding process, it is necessary to control the stranding pitch to ensure the roundness and mechanical properties of the conductor. After stranding, the surface of the conductor is treated to remove oil and oxide layers on the surface to ensure the cleanliness of the conductor.

Insulation Extrusion: Extruding the PVC insulation layer outside the conductor is a key link in the production process. First, PVC resin is mixed evenly with additives such as stabilizers, plasticizers, and lubricants in a certain proportion to make insulation materials. Then, the insulation material is added to the extruder, heated and melted, and evenly extruded and coated on the surface of the conductor through a mold to form an insulation layer. During the extrusion process, parameters such as extrusion temperature, speed, and pressure must be strictly controlled to ensure that the insulation layer has uniform thickness, smooth surface, and is tightly combined with the conductor without defects such as bubbles and impurities.

Cabling Process: For 3-Core Cables, it is necessary to cable 3 cores wrapped with insulation layers. During cabling, the 3 cores are twisted together according to a certain twisting direction and pitch, and at the same time, some filling materials are filled during the twisting process to make the structure of the cable more round and stable. The filling material is usually polypropylene rope, which has certain elasticity and corrosion resistance.

Sheath Extrusion (Some Models): Some models of Cyky series cables may also need to extrude a layer of PVC Sheath outside the cabled core to enhance the mechanical protection performance of the cable. The sheath extrusion process is similar to insulation extrusion. The sheath material is added to the extruder and extruded outside the cabled core. The thickness and quality of the sheath also need to be strictly controlled to ensure that it can effectively protect the inner core.

Inspection and Testing: Strict inspection and testing are required in all links of the production process. Parameters such as the diameter and resistance of the conductor need to be sampled and tested; the thickness, voltage resistance performance, mechanical performance, etc. of the insulation layer also need to be tested; the outer diameter and roundness of the cabled cable need to be checked; the finished cable also needs to undergo overall performance tests, such as temperature resistance test, bending test, insulation resistance test, etc. Only products that pass all tests can leave the factory for sale.

Packaging Materials: Cable reels are usually used as the main packaging carrier, and there are two types of cable reels: wooden and steel. Wooden cable reels have low cost and light weight, suitable for short-distance transportation; steel cable reels have higher strength and stronger bearing capacity, suitable for long-distance transportation and packaging of large cables. The size of the cable reel is selected according to the length and diameter of the cable. Generally, the length of each reel of cable is 100 meters, 200 meters, or 500 meters. On the cable reel, the cable is tightly wrapped with a plastic film to prevent the cable from being affected by dust, moisture, and direct sunlight. For some small batches of short cables, carton packaging may also be used. Buffer materials such as foam are placed inside the carton to avoid damage caused by mutual collision during transportation.

Packaging Marks: Clear packaging marks are printed on the surface of the cable reel or carton. The marks include product name, model, specification, length, rated voltage, manufacturer, production date, execution standard, and other information, which is convenient for users to identify and accept. At the same time, some warning signs such as "Do Not Invert", "Handle with Care", "Moisture-proof and Sun-proof" are also printed to remind transportation and storage personnel to handle the cable correctly.

Packaging Requirements: During the packaging process, it is necessary to ensure that the cable is neatly wound on the cable reel to avoid distortion and knotting. The two ends of the cable need to be sealed to prevent moisture and impurities from entering the inside of the cable. For cables packaged in cartons, it is necessary to ensure that the cartons have sufficient strength to withstand a certain pressure and avoid being crushed during stacking.

Transportation Methods: Cyky series cables can be transported by various means such as road transportation, railway transportation, and waterway transportation. Road transportation has high flexibility and can realize door-to-door service, suitable for short-distance and small-batch transportation; railway transportation has large capacity and low cost, suitable for medium and long-distance and large-batch transportation; waterway transportation is suitable for long-distance transportation, especially for coastal areas or places with ports, with low transportation costs. When choosing the transportation method, it is necessary to comprehensively consider factors such as the quantity of cables, transportation distance, and time requirements.

Transportation Precautions: During transportation, it is necessary to ensure that the packaging of the cable is intact to avoid mechanical damage to the cable caused by extrusion, collision, and dragging. The cable reel should be placed horizontally, and inversion or tilting is strictly prohibited to prevent the cable from falling off the cable reel. The compartments and cargo holds of transport vehicles or ships should be kept clean and dry, without sharp objects and corrosive substances. During transportation, measures for moisture-proof, sun-proof, and rain-proof should be taken, such as covering the cable with a tarpaulin to avoid the cable being affected by bad weather. At the same time, traffic rules and transportation regulations must be observed to ensure transportation safety.

Transportation Responsibility: The transporter shall be responsible for the transportation process of the cable and ensure that the cable is delivered to the destination on time and safely.
