It can be applied in new energy, rail transit, industrial manufacturing and intelligent buildings. The expansion is a technological leap and a commitment to sustainable development, and Wanruitong will offer full - lifecycle service to be a trusted partner for customers.

Breakthrough in research and development, defining new standards


After more than half a year of technical breakthroughs and rigorous testing, Wanruitong announced that the 1.8/3kV power cable has successfully expanded its scope and passed the type test of the National Special Wire and Cable Product Quality Inspection and Testing Center, and has been awarded the production license by the Guangdong Provincial Administration for Market Regulation.






This cable is designed for efficient and safe power transmission scenarios, breaking through traditional material and process limitations, redefining the performance benchmark of medium and low voltage cables with higher voltage resistance, stronger environmental adaptability, and longer service life.

Core technological advantages, forging excellent quality

1. Super strong insulation protection


Triple insulation guarantee: Adopting a composite structure of cross-linked polyethylene (XLPE) insulation layer and metal shielding layer, the withstand voltage level reaches 1.8/3 (3.6) kV, the insulation resistance is increased by 30%, and the breakdown risk approaches zero.


Weather resistance upgrade: Special modified materials can withstand extreme temperature differences from -40 ℃ to 90 ℃, resist UV rays, acid and alkali corrosion, and are suitable for complex environments such as outdoor, underground, and humid environments.


2. Intelligent security design


Shielding technology: Copper strip shielding structure effectively suppresses electromagnetic interference, ensures signal transmission purity, and meets the requirements of precision industrial equipment.


Flame retardant and environmentally friendly: The sheath is made of low smoke halogen-free (LSZH) material and has passed the IEC 60332-1 flame retardant certification. It releases non-toxic smoke during combustion, providing safety protection for densely populated areas.


3. High efficiency, energy saving and economy


Ultra low conductor loss: 99.99% high-purity oxygen free copper conductor, with a conductivity increase of 5%, reducing energy waste and helping enterprises reduce costs and increase efficiency.


Flexible structural design: Optimize cable bending radius (≥ 12D) for easy installation in narrow spaces, reducing construction difficulty and overall costs.


Accurately adapting to scenarios and empowering diverse fields


In the field of new energy: photovoltaic power stations, wind farm collection systems, weather resistant and lightning resistant, ensuring stable transmission of clean energy.


Rail transit: Subway and high-speed rail power supply network, resistant to vibration and electromagnetic interference, ensuring zero interruption of operation.


Industrial manufacturing: Heavy machinery, automated production line power supply, high current capacity to support continuous operation of high-power equipment.


Intelligent buildings: commercial complexes, data center power distribution, flame retardant and environmentally friendly characteristics in line with green building standards.


Full lifecycle service, a worry free choice for customers


The successful expansion of 1.8/3kV cables is not only a technological leap, but also a commitment to sustainable development. Whether in the wave of energy transformation, infrastructure upgrading, or intelligent manufacturing, Wanruitong will become a trusted partner for our customers with reliable products and comprehensive services.
