Heat Shrinkable Cable Termination

Heat Shrinkable Cable Termination

For connection of cable to switchgear terminal, transformer terminal, poles etc. termination kits are required. The Heat Shrinkable Termination kits can be used indoors or outdoors based on actual application.

  • C. Voltage withstand
    • Dry: A.C. 35 kV/I min.
    • Wet: A.C. 35 kV/ I min.
  • DC Voltage withstand 48 kV for 30 min.
  • Impulse Voltage withstand 75 kV 10 + VE and 10 - VE Shots

There are a wide range of cable jointing systems available today, which can be classified by the way they are applied, such as:

  • Taped type
  • Pre-moulded/push-on/slip-on type
  • Cold application type
  • Heat shrinkable type

The selection criterion for an appropriate type of cable jointing system by the user should be dependent on the site conditions, operating parameters, voltage applications and cable types.

Compact Substation

Our compact substation units have high-fire-point fluid, providing fire safety benefits, and a projected life well beyond that of a traditional mineral-oil transformer.

Three-phase, pad-mounted transformers, for use on underground power distribution systems, are best suited for commercial applications in public access areas and where underground service is required. These transformers meet modern design requirements for flexibility and provide a visually pleasing installation.

Construction allows installation in locations accessible to the general public without the need for protective fencing or vaults. These units are ideally suited for apartment buildings, schools, hospitals, shopping centres, commercial buildings, or industrial sites.
