LT XLPE Power Cables

Why Choose Us?

Aluminium-conductor, XLPE-insulated underground cables engineered for safe, reliable power distribution up to 1.1 kV.  Available in armoured and unarmoured variants, these cables combine high thermal and mechanical performance with low dielectric losses, ideal for industrial, commercial, and residentialinstallations.

High Thermal Stability

XLPE insulation supports 90 °C continuous, 120 °C overload, and 250–280 °C short-circuit operation for reliable performance

Mechanical Protection

GI strip/wire armour for multicore and aluminium armour for single-core cables ensures reliable external protection.

Low Dielectric Losses

Optimized insulation reduces power losses, ensuring efficient energy transfer and lower operating costs.

Fire-Safe Options

PVC-ST2 sheath with FRLS (Flame-Retardant Low Smoke) and LSZH (Low Smoke Zero Halogen) variants for enhanced fire safety.

Chemical & Oil Resistance

Provides reliable durability against oils, chemicals, and harsh industrial environments.

Flexible Installation

Stranded aluminium conductors and optimized bending radius (12× cable Ø) for easy routing and termination.

Applications

  • Underground power distribution in industrial, commercial, and residential complexes
  • Suitable for outdoor and indoor feeder lines with weather-resistant sheathing for long-term reliability.
  • High-load circuits in manufacturing plants, data centers,  and high-rise buildings
  • Replacement of ageing duct-bank networks requiring  enhanced safety standards

Applicable Standards

  • IS 7098 Part 1 – XLPE-insulated cables up to 1.1 kV (primary reference).
  • IS 8130 – Aluminium conductor specifications (solid & stranded).
  • IEC 60502-1 – Power cables with extruded insulation (LV).
  • IEC 60332 – Flame-propagation testing (preferred over IEEE 383 in India).
