Low Voltage Wires and Cables

Low-voltage (LV) wires and cables are engineered for power distribution systems in indoor buildings and instrumentation equipment. Featuring PVC or XLPE insulation with a PVC jacket, these cables deliver exceptional electrical and insulating performance, as well as heat resistance and environmental durability. They also provide stable mechanical strength and ease of installation, ensuring long-term operational safety and system reliability.

Low-Smoke-Free-Halogen Material

Low-Smoke, Free-Halogen (LSFH) jacketing material is also an available option. The material features low-smoke emission, non-toxic properties, and flame retardancy, significantly enhancing the safety and fire prevention performance of the wires and cables.

Environmental Compliance

Building wires and cables are supplied in RoHS-compliant variants.

Under normal operating conditions, the service life of Low-voltage (LV) wires and cables is as shown in the table below:

Type Installation Condition Service Life
Insulated Wires
(e.g., IV, HIV)
Indoor installation, within conduits or piping, and wiring inside panels 20 years
Outdoor installation 15 years
Low-Voltage Cables
(e.g., VV, CVV, XLPE-PVC)
Indoor and outdoor installation (not exposed to water) 20 years
Outdoor installation (exposed to water) 15 years

Factors that may cause deterioration of electrical wires and cables, resulting in a shortened service life, including:

  1. Electrical factors
  2. Water ingress within electrical wires and cables
  3. Mechanical factors
  4. Temperature-related factors
  5. Chemical factors
  6. Exposure to ultraviolet radiation, ozone, and salt deposition
  7. Damage caused by rodents, termites, and other pests
  8. Microbial effects
  9. Poor installation or improper workmanship
