YJV33/Copper core cross-linked polyethylene insulated polyvinyl chloride sheathed steel wire armored power cable
YJV33/
YJV33 copper core steel wire armored power cables are designed for complex and harsh environments. As a conductor, the high-purity copper core has excellent conductivity and low resistance, ensuring stable and efficient power transmission; the cross-linked polyethylene insulating layer has excellent electrical insulation and high temperature resistance. The long-term working temperature of the conductor can reach 90℃, and the maximum temperature during short circuit shall not exceed 250℃. The "33" in the model indicates that it uses wire armor and PVC outer sheath. Compared with ordinary armor, steel wire armor gives cables stronger mechanical strength and can withstand greater tension and impact forces. It is especially suitable for scenarios where it needs to withstand greater mechanical external forces or needs to be laid vertically or underwater, such as mines, seabeds, etc. The outer polyvinyl chloride sheath has both wear resistance, moisture resistance and corrosion resistance, further improving the adaptability of the cable environment. This cable is suitable for power transmission and distribution systems of 0.6/1kV and below, and is widely used in special fields such as mining, water conservancy projects, and submarine cables. It is a reliable guarantee for power transmission under extreme working conditions.

YJV33 Copper Core XLPE Insulated PVC Sheathed Steel Wire Armored Power Cable: Heavy-Duty Protection for Industrial Power Systems
YJV33 is a robust"copper core cross-linked polyethylene insulated polyvinyl chloride sheathed steel wire armored power cable"designed to excel in harsh industrial, underground, and high-mechanical-stress environments. Combining a copper conductor, XLPE insulation, PVC sheath, and steel wire armor, this cable delivers exceptional electrical performance, durability, and protection for medium-to-high-voltage applications.
Rugged Design for Extreme Conditions
- Copper Conductor: The oxygen-free copper core ensures superior electrical conductivity (≤0.0172 Ω·mm²/m) and low resistance, making it ideal for power transmission in medium-voltage systems (up to 35kV). Its high conductivity minimizes energy loss, even over long distances.
- XLPE Insulation: Cross-linked polyethylene provides excellent thermal stability (rated for 90°C continuous use) and dielectric strength, resisting moisture, chemicals, and electrical stress. This insulation ensures reliable performance in demanding environments.
- Steel Wire Armor: The helical steel wire armor offers unparalleled mechanical protection against crushing, pulling, and impact, making YJV33 suitable for direct burial, underwater installations, or areas with heavy vehicular traffic. The armor also provides EMI shielding for sensitive electronic systems.
- PVC Sheath: The outer polyvinyl chloride layer enhances protection against corrosion, UV radiation, and chemical exposure, extending the cable’s lifespan in outdoor and industrial settings.
Applications in High-Stress Environments
- Industrial and Mining Sites: Powers heavy machinery, conveyor systems, and substation connections in factories, mines, and quarries, where the steel wire armor protects against physical damage from equipment or falling debris.
- Underground and Submarine Cabling: Used for direct burial in urban power grids, cross-river pipelines, and offshore platforms, ensuring reliable power transmission despite extreme external pressures.
- Transportation Infrastructure: Installed in railways, airports, and tunnels to supply power to signaling systems, lighting, and ventilation, with the armor resisting vibration and mechanical stress.
- Renewable Energy Projects: Supports power collection in wind farms and solar plants, where the cable’s durability withstands harsh weather conditions and frequent mechanical movement.
Performance and Compliance
- Mechanical Ratings: Withstands radial crushing forces up to 5000N/m and axial tension up to 1000N, ensuring resilience in rugged installations.
- Electrical Stability: Rated for 6/10kV and 26/35kV systems, with short-circuit withstand temperatures of 250°C, providing reliable performance during overloads.
- Standards Compliance: Meets IEC 60502, GB/T 12706, and IEEE 383 standards, ensuring compatibility with global industrial and utility requirements.
Why YJV33 is a Top Choice for Heavy-Duty Projects
- Uncompromising Protection: The steel wire armor and PVC sheath create a robust barrier against physical damage, moisture, and corrosion, reducing maintenance and replacement costs.
- Installation Versatility: Suitable for both vertical and horizontal routing, including challenging terrains, thanks to its flexible armor and durable construction.
- Long-Lasting Performance: Engineered for a service life of 50+ years, YJV33 offers exceptional value for large-scale infrastructure projects, ensuring reliable power distribution for decades.
