IllustrationOverview
HT & LT Power Cables from Fortune Fittings Private Limited
IllustrationLT (low tension) cables carry power and control signals at up to 1.1 kV inside plants, buildings and substations. They are supplied with PVC insulation for general duty, or XLPE insulation where higher current, higher temperature or better short-circuit performance is needed.
HT (high tension) cables carry power from 3.3 kV up to 33 kV between substations, transformers and large motors. They are XLPE insulated with semiconducting screens and a metallic screen around each core, and are built to the specification set in your tender.
Both are available with steel wire or strip armour for direct burial and mechanical protection, or with aluminium armour for single-core AC circuits, and with FR, FRLS, LSZH or HDPE outer sheaths.
Construction
- Conductor
- Stranded, compacted or sector-shaped copper or EC-grade aluminium (IS 8130)
- Insulation
- PVC (LT) or XLPE (LT and HT), with semiconducting screens on HT
- Metallic screen (HT)
- Copper tape or wire screen per core
- Armour
- Galvanised steel round wire or strip; aluminium for single-core AC
- Outer sheath
- PVC ST1 / ST2, FR, FRLS, LSZH or HDPE
Applications
- Plant power distribution and motor feeders
- Substations, transformers and switchyards
- Commercial buildings and infrastructure projects
- Control and instrumentation wiring
- Direct burial, duct and cable tray installation

Features
What to expect
- XLPE runs at 90 °C continuous and 250 °C short-circuit, against 70 °C / 160 °C for PVC
- Higher current rating and smaller bending radius with XLPE
- Routine tested for conductor resistance, high voltage and partial discharge (HT)
- Supplied on drums in project lengths
