I. From the Perspective of the Product Itself
(I) Specification Parameters
YJV32 3×150mm²+240mm² steel wire
Armoured Cable has rigorous and detailed settings in terms of specification parameters, which collectively determine the performance and application scope of the cable.
In terms of conductor specifications, the cable includes 3 main cores of 150mm² and 1 neutral core of 240mm². The main cores are responsible for the main power transmission task. The cross-sectional area of 150mm² can ensure transmission efficiency while effectively reducing the loss generated when current passes through. The 240mm² neutral core plays an important role in balancing current and stabilizing voltage in the three-phase four-wire power system, ensuring the safe and stable operation of the power system.
The overall outer diameter of the cable is also a key parameter, which directly affects the installation and laying methods of the cable. After precise measurement and design, the outer diameter of the cable can adapt to various installation scenarios, and can well meet the relevant requirements whether it is direct burial, pipe threading or overhead laying.
In terms of rated voltage, YJV32 3×150mm²+240mm² steel wire armoured cable has a high rated voltage level, which can meet the needs of medium and high-voltage power transmission. This makes it widely used in places that require high-voltage power supply such as industrial plants and large buildings.
In addition, the bending radius of the cable is also clearly specified. A reasonable bending radius ensures that the cable will not damage the internal structure due to excessive bending during installation, thus ensuring that its electrical and mechanical properties are not affected. Generally speaking, its bending radius is not less than a certain multiple of the cable outer diameter, and the specific value will be strictly controlled according to different installation environments and requirements.

Flexibility and reliability, and can adapt to the complex structural layout inside the building. YJV32 3×150mm²+240mm² steel wire armoured cable supports a variety of installation methods, which can be laid according to the specific needs of the building, providing stable power support for building lighting, air conditioning, elevators and other equipment.
(III) Material and Style
Material
The material selection of YJV32 3×150mm²+240mm² steel wire armoured cable is the basis for its excellent performance. Each material has been carefully selected and strictly tested.
The conductor is made of high-purity copper, which has excellent electrical conductivity, can transmit electricity efficiently and reduce energy loss. High-purity copper can reduce the resistance of the conductor, improve the conductivity of the cable, and ensure that the electricity will not be affected too much by the
Conductor Material during transmission. At the same time, copper also has good ductility and toughness, which is easy to be processed into the required core shape, and is not easy to break during installation and use.
The insulation layer uses cross-linked polyethylene (XLPE), which has many advantages. Firstly, it has excellent temperature resistance and can maintain stable insulation performance in a wide temperature range, and is not easy to age and damage even in high-temperature environments. Secondly, XLPE has excellent electrical insulation performance, which can effectively prevent current leakage and ensure the safe operation of the cable. In addition, it also has good chemical corrosion resistance and mechanical strength, which can resist the erosion and damage of the external environment to the insulation layer.
The outer armour is made of galvanized steel wire. The galvanizing treatment makes the steel wire have good corrosion resistance, which can prolong the service life of the armour layer. The steel wire itself has high strength and hardness, and the formed solid protective layer can effectively resist external extrusion, impact and gnawing by rodents, providing reliable protection for the inner core and insulation layer of the cable.
Style
In terms of appearance style, YJV32 3×150mm²+240mm² steel wire armoured cable presents concise and regular characteristics. The cable as a whole is cylindrical, with a compact structure and orderly arrangement of cores. The outer galvanized steel wire armouring layer forms a uniform protective structure, which not only plays a protective role, but also makes the cable have certain rigidity, facilitating laying and fixing during installation.
This style design not only considers the functional requirements of the cable, but also takes into account the convenience of installation. The simple appearance enables the cable to better integrate with the surrounding environment during laying, without occupying too much space, and is also convenient for inspection and maintenance.
(IV) Production Process
The production process of YJV32 3×150mm²+240mm² steel wire armoured cable adopts a series of advanced production technologies to ensure the quality and performance of the product.
In the conductor manufacturing link, first, high-purity copper is smelted and cast to form copper rods. Then, the copper rod is drawn into
Copper Wire of the required diameter through the wire drawing process. During the wire drawing process, the drawing speed and temperature need to be strictly controlled to ensure the dimensional accuracy and mechanical properties of the copper wire. After that, multiple copper wires are stranded to form a core. The stranding process can improve the flexibility and overall strength of the core.
The insulation layer is made by cross-linking process. The polyethylene material is cross-linked to change its molecular structure from linear to network, thereby improving the temperature resistance, mechanical strength and insulation performance of the material. During the cross-linking process, parameters such as temperature, pressure and time need to be accurately controlled to ensure that the cross-linking reaction is sufficient and uniform. Then, cross-linked polyethylene is evenly wrapped around the conductor through extrusion molding process to form an insulation layer, ensuring that the insulation layer has uniform thickness and smooth surface.
The stranding of the cable core is to strand 3 main cores and 1 neutral core according to a certain pitch. During the stranding process, it is necessary to ensure the stable position of the cores to avoid mutual friction and extrusion. The
Stranded Cable core needs to be bound and fixed to enhance the stability of the overall structure.
In the production process of the outer armour, first, galvanized steel wires are wound around the cable core according to a certain rule to form the armour layer. During the winding process, the tension and winding density of the steel wire should be controlled to ensure the uniformity and tightness of the armour layer. After the armour layer is formed, necessary treatments such as coating anti-corrosion coating are required to further improve its corrosion resistance.
Throughout the production process, there is also a complete quality inspection process. From the inspection of raw materials to the quality control of each production process, and then to the final inspection of finished products, advanced testing equipment and strict testing standards are adopted. For example, the resistance of the conductor, the insulation resistance and voltage resistance performance of the insulation layer, and the strength of the armour layer are comprehensively tested to ensure that each batch of cables meets the relevant quality standards and technical requirements.
II. From the Perspective of Product General Information
(I) Packaging
The packaging design of YJV32 3×150mm²+240mm² steel wire armoured cable fully considers the product protection, transportation and storage needs, and adopts a scientific and reasonable packaging method.
For coiled cables, wooden reels are usually used for packaging. The wooden reel has high strength and stability, which can bear the weight of the cable and prevent deformation or damage during transportation and storage. When the cable is wound on the wooden reel, it will be wound according to a certain tension to ensure that the cable is arranged neatly and avoid mutual winding and extrusion. On the outer layer of the cable, a moisture-proof and dust-proof plastic film will be wrapped to prevent the cable from being polluted by the external environment and eroded by moisture.
For shorter cables or samples, cartons or wooden boxes may be used for packaging. The size of cartons and wooden boxes will be customized according to the length and diameter of the cable to ensure that the cable can be placed tightly in them to avoid shaking and collision during transportation. Inside the package, some buffer materials such as foam and bubble film will be placed to further enhance the protection of the cable.
