HT Cables
HT (High Tension) cables are specially designed power cables used to transmit high voltage electricity, typically ranging from 1.1kV to 33kV. These cables are built with robust insulation and protective layers to handle high electrical loads safely and efficiently over long distances. Commonly used in industrial plants, power grids, and infrastructure projects, HT cables ensure reliable and loss-minimized energy transmission.
Types Available
- Single-core and multi-core HT cables
- Copper and Aluminium conductor variants
- Unarmoured and armoured (strip/wire) types
- FRLS / HR PVC / XLPE / LSOH sheathing options
Construction
- Conductor: Electrolytic grade, stranded aluminium or copper
- Insulation: XLPE (Cross-linked Polyethylene) for high thermal resistance
- Inner Sheath: PVC or semi-conducting compound
- Armour: Galvanised Steel Strip/Wire (for mechanical protection)
- Outer Sheath: FR/FRLS/LSOH PVC as per requirement
- Voltage Grade: 6.6kV, 11kV, 22kV, 33kV
