LT 1.1 KV Unarmoured Power Cables (Single core & Multi core)
Insulation
Unarmored cables have no protective steel covering rather covered with a plastic coating. Cable insulation material used is of a high resistance to the flow of electric current to prevent leakage of current from a conductor. The insulation over the conductor is done by extrusion process.
Conductor (Copper / Aluminum)
Copper or Aluminum used for the conductors, are obtained in the form of 8.0 mm copper or 9.5 aluminum rods. After testing rods are drawn into wires of required sizes. These wires are formed into final conductor in the stranding machines under strict ‘Quality Assurance Program’
