NH-VV Fire-Resistant Cable

QIFAN NH-VV Fire-Resistant Cable is a high quality cable product for low voltage power transmission. It adopts high-quality copper core and insulation material to ensure the high efficiency and reliability of power transmission.

The conductor of the cable is made of high-quality copper material, the electrical performance is stable and reliable, the rated voltage is 450/750V, and the maximum working temperature is 70°C.

The cable uses PVC insulation, which has good chemical and abrasion resistance. This allows it to be used in a variety of harsh environments such as wet, corrosive or high temperature environments

In addition, the cable complies with international standards and safety standards, and has a long service life and good safety performance. It has been rigorously tested and inspected to ensure its quality and reliability.

Advantages of NH-VV Fire-Resistant Cable

  • The wire uses high-quality polyvinyl chloride as the insulation material, which has good heat resistance. It can work at higher temperature without melting or deforming the insulating material, ensuring the safety and reliability of the wire.

  • PVC material has excellent corrosion resistance and can resist the erosion of many chemical substances, including acids, alkalis and solvents. This makes it suitable for use in a variety of environmental conditions, including wet, acidic or alkaline environments.

  • The wire has good electrical properties, providing stable current transmission and low resistance. It has low resistance and inductance, which can reduce energy loss and signal attenuation, ensuring the efficiency and quality of power transmission.

  • The wire is flexible and bendable for easy installation and routing. Its skin is smooth, not easily damaged, and has good wear resistance. This allows installers to quickly and easily complete the routing and connection of wires, improving work efficiency.
