Power cable accessories play crucial role in keeping electrical installations human safe and long lasting. The tough environment condition is a very common aspect in industrial and commercial setups. Electrical installations in such places need extra insulation protection to keep the cables and other parts protected against chemical, mechanical, thermal, and other impacts. Here comes the role of heat shrink technology that facilitates to produce a range of heat-shrink tubes and cable joint accessories.
Heat Shrink Accessories for Different Power Cables:
Electrical insulation is must for every type of power cable joint but the way of insulation varies according to the type of cables. There exist a number of power cable types having different kinds of wires structuring and insulation. Electrical power cables play vital role in industrial set ups because even a short breakdown costs heavy. The selection of heat shrink electrical accessories depends upon the type of cables to be joint or insulated. Based on manufacturer –side insulation types, we can classify low-tension cables and high tension cables as – H type cables, SL type cables, S.L Cables etc.
The most used conventional insulation types for power cables used for commercial, industrial and large distribution set-ups are – PVC insulation, PE insulation, PP insulation, PUR insulation, and Nylon insulation. Rubber wire insulations like TPR Insulation, Silicone Rubber Insulation, Styrene-Butadiene Insulation are also used for special category power cables. Fluoropolymers wire insulations are also used to make the cables suitable for -80°C to 200°C temperature. So you get properly insulated cables when you buy but you need external insulation at the time joining the cables or leaving the ends of cables. Here comes the role of heat shrink power cable accessories.
A Range Of Heat Shrink Electrical Cable Accessories: The increasing adaption rate of heat shrink technology is encouraging the heat shrink tubes and other accessories manufacturers to expand their product range. Today, leading heat shrink accessories manufacturers offer tailored-to-need products also for bulk requirements. The most used heat shrink insulation accessories are –
- Heat Shrink Sleeves or heat shrink tubes
- Heat shrink Cable Terminations
- Heat shrink Cable Joints
- Heat shrink Cable End Caps
Characteristics of Heat-Shrink Power Cable Accessories:
Each heat shrink electrical accessory is developed with specific characteristics for a specific application range. Heat shrink insulation delivers unique attributes to electrical conductors that they insulate. Choosing a correct insulation for a particular cable or specific application may be a complex task but the top manufacturers, suppliers, and exporters like Gala Thermo in Mumbai offer online assistance also to simplify the task. The special insulation characteristics that make heat shrink electrical accessories a must use for large electrical set-ups in challenging environmental conditions are –
- UV resistance (At every 500m of altitude, the UV radiation increases 3.5%)
- Pollution resistance
- Salt Fog resistance
- Oil and grease resistance
- Flame retardant
- Fire resistance
- Gamma radiation resistance
- System/structure integrity up to 180 min
In high hazardous areas prone to fire accidents, the heat shrink cable accessories are used in conjunction with additional fire protective layers to act as a barrier against the flames preventing them to reach inner insulation.
