Product Description
YJV42 is a copper conductor, cross-linked polyethylene insulated, thick steel wire armored, and polyvinyl chloride sheathed power cable. Here is a detailed description:
I. Structural Components
- Conductor: Made of high-quality copper, renowned for its excellent electrical conductivity and thermal conductivity. The conductor is carefully stranded to ensure flexibility and durability, facilitating installation in various construction environments.
- Insulation: Cross-linked polyethylene (XLPE) is used as the insulation material. XLPE offers outstanding electrical insulation properties, high heat resistance, and aging resistance. Through a special chemical or physical treatment, its molecular structure changes from linear to reticular, significantly enhancing the mechanical strength and electrical performance of the material. This effectively prevents current leakage and short-circuit faults.
- Armoring: The armor layer is made of thick steel wire, providing powerful mechanical protection. The thick steel wire armor can withstand significant tensile, compressive, and impact forces, safeguarding the conductor and insulation inside the cable from external mechanical damage. For example, during cable installation, if there is excavation or rolling on the ground, the thick steel wire armor can effectively protect the cable. In scenarios with vertical installation or high-drop installation, it also ensures the stability and safety of the cable.
- Sheath: The sheath is made of polyvinyl chloride (PVC), which has good corrosion resistance, waterproofing, and flame retardancy. The PVC sheath protects the cable from the erosion of external chemicals, prevents moisture from entering the cable interior, and provides a certain degree of flame retardancy in case of fire, reducing the damage to the cable.
II. Performance Characteristics
- Excellent electrical performance: With high-quality copper conductor and XLPE insulation material, YJV42 cable has low resistance and good insulation performance, ensuring efficient power transmission and reducing power loss. The maximum rated operating temperature of the conductor is 90°C. In case of a short circuit (with a maximum duration of no more than 5 seconds), the maximum temperature of the cable conductor does not exceed 250°C, suitable for various working environments.
- High mechanical strength: The thick steel wire armor structure endows the cable with strong tensile, compressive, and bending resistance, enabling it to adapt to complex laying environments and mechanical stresses. For example, in some occasions that require frequent movement or bending, YJV42 cable can still maintain good performance.
- Good waterproof performance: The PVC sheath and good sealing structure give the cable certain waterproof performance, allowing it to be used in humid environments. However, if it is used in long-term immersion in water or in special underwater environments, further waterproof measures or the selection of specialized underwater cables may be required.
- Strong corrosion resistance: The sheath and armor materials of the cable have good corrosion resistance, able to resist the erosion of acids, alkalis, salts, and other chemicals, suitable for corrosive environments such as chemical plants and mines.
III. Applicable Scenarios
- Mine environments: In mines, cables need to withstand large mechanical stresses and harsh environmental conditions. The thick steel wire armor and good insulation performance of YJV42 cable enable it to operate safely and reliably in mines, providing power support for mining equipment.
- Industrial installations: Suitable for various industrial settings where reliable power transmission is required. It can handle the mechanical stresses and environmental challenges often encountered in industrial facilities.
- Power stations: Can be used in power stations to transmit power from generators to the grid or within the station. Its high mechanical strength and electrical performance make it a reliable choice for such applications.
IV. Production Standards
The production of YJV42 cable complies with international standards such as IEC 60502. These standards specify in detail the cable's structure, performance, test methods, acceptance rules, etc., to ensure the quality and reliability of the cable.

Packaging & Shipping
We are pleased to provide you with information regarding the packaging and transportation of our YJV42 and YJV32 cables. Here are the key points to note:
Packaging:
- Our cables are carefully packaged to ensure their integrity during transit. The packaging materials used are of high quality and designed to protect the cables from moisture, dust, and mechanical damage.
- The cables are typically wound on wooden or metal reels. The reels are sturdy and provide a convenient way to handle and store the cables.
- Each reel is clearly labeled with the cable type, size, length, and other relevant information. This helps in easy identification and proper handling during transportation and installation.
Transportation:
- We offer various transportation options to meet your specific requirements. These may include sea freight, air freight, or land transportation depending on the destination and urgency of your order.
- For sea freight, the cables are loaded onto shipping containers that are properly secured and sealed to protect against the elements. We ensure that the containers are compliant with international shipping standards.
- In case of air freight, the cables are packaged in a way that meets the requirements of air transportation regulations. Special care is taken to ensure that the weight and dimensions of the packages are within the limits allowed by the airlines.
- During transportation, we monitor the shipment to ensure its timely delivery. We provide you with tracking information so that you can keep track of the progress of your order.
- Upon arrival at the destination, the cables should be inspected for any damage that may have occurred during transit. If any issues are found, please contact us immediately so that we can resolve them promptly.
We understand the importance of proper packaging and transportation to ensure the quality and performance of our products. If you have any specific requirements or concerns regarding the packaging and transportation of your order, please do not hesitate to contact us. We will do our best to meet your needs and ensure a smooth delivery process.
Our Advantages
Before making cables, the selection of copper materials is of utmost importance. The copper materials we choose are all 99.99% oxygen-free copper rods.
Before production, conduct a circular inspection of the equipment to ensure that the probability of problems occurring at the production end is 0%.
Professional production equipment and strict requirements for product quality are our lifelines.
Conduct self-inspection during production, spot check by batch, and conduct ex-factory inspection after leaving the factory. Conduct product production supervision in strict accordance with steps that far exceed the ISO 9001 quality control standard.
Ultra-large-scale inventory is also one of our advantages.
Not only do we have cables and wires. We are a group company. Under the company, there is a power design institute, a power installation company, a production plant for power distribution boxes and cabinets, a production plant for cable trays and cable accessories, and a production plant for cable conduits. We can provide integrated services from design and research to products and then to construction. If you have any power-related issues, we welcome you to discuss with us. We will do our best to provide a solution. And these services are permanently free of charge!!!
