PVC LT Underground Cables

Why Choose Us?

Durable, cost-effective PVC-insulated cables designed for low-voltage underground power distribution up to 1.1 kV. Available in single- and multi-core armoured variants, these cables deliver proven performance and safety in residential, commercial, and industrial installations.

Reliable Insulation

 PVC Type C (IS 5831) offers stable dielectric strength in varied high temperature conditions.

Mechanical Protection

 Galvanized steel strip/wire armour guards against external damage.

Flame-Retardant Options

IS 1554 (Part 1) is still valid but largely superseded by IS 7098 (Part 1); mention both for clarity.

Environmental Resistance

Environmental Resistance: Resistant to most oils, chemicals, and water, ideal for burial and duct installations.

Flexible Installation

 Stranded conductors and 12× diameter minimum bending radius simplify routing and jointing.

Cost-Effective

Optimized design for economical low-voltage networks without compromising on durability.

Applications

  • Underground power distribution in homes, offices, and factories
  • Cable trenches, duct banks, and direct burial installations
  • Utility feeder lines in substations and power plants
  • Mechanical-protection-critical circuits in outdoor and semi-outdoor settings
  • Low-voltage networks up to 1.1 kV across residential and commercial zones

Applicable Standards

  • IS 7098 – PVC-insulated cables for rated voltages up to 1.1 kV
  • IS 8130 – Aluminium and copper conductor specifications
  • IS 1554 – Power cables with extruded insulation for rated voltages up to 30 kV
  • IEC 60332 – Tests on electric‐cable flame propagation
