35KV 3 Core Indoor Heat Shrinkable Insulation Tools Electric Terminal
Heat Shrink Termination for screened, 3-core polymeric insulated cables
The indoor termination is designed for screened three core polymeric insulated MV cables up to 35kv.
Stress control tube is used to smooth out the electrical field at the cable screen end. All phase cores are covered with anti-tracking insulation tube and sealing tube. Anti-tracking rain sheds increase surface creepage distance to ensure safety. The crutch area is sealed and protected with an adhesive-coated breakout which is installed over the cores and the end of oversheath. In case of 10kv cables, a 3-core rain shed is supplied in the kit.
Work Temperature: the use age is more than 20years under the -50°C~95°C environment
Shrink Ratio: radial direction≥50%, axial direction ≤10%
Shrink Temperature: 120°C~140°C

Design of Termination
LDDQ provides a universal system for indoor and outdoor termination for paper or polymeric insulated cables
1. Electrical Stress Control | Stress control tube is used to smooth out the electrical field at the cable end. |
2. Excellent Anti-tracking properties | Anti-tracking insulation tubes and rain sheds have an excellent tracking and erosion resistance. |
3.Additional Creepage | Anti-tracking rain sheds increase surface creepage distance. |
4. Moisture Sealing | Durable sealing is achieved by hot-melted adhesive on the inside of sealing tube and anti-tracking insulation tube. In case of 3-core cables, the crutch area is sealed and protected with an adhesive-coated breakout which is installed over the cores and the end of oversheath. |
5. Earth Connection | Either soldering or solderless earth connection is available to connect metal screen or armour to ground. For cables with wire screen, copper wires are imbedded in the sealing mastic to prevent any corrosion by moisture sealing. |
