Highlights
- Provides a void-free seal to tape shield, wire shield and UniShield® power cables
- High dielectric-constant material regulates the distribution of electric field stress
- Suitable for indoor applications
- Non-tracking, molded, silicone rubber insulation offers durability
- Includes 3 non-skirted, 1-piece, 3-phase, cold shrink terminations
3M™ Cold Shrink QT-III Silicone Rubber Termination Kit 7620-T and 7690-T Series contains one-piece, non-skirted, silicone rubber terminations, meets IEEE Standard 48 Class 1 for indoor and weather-protected applications. The kits are designed for terminating solid dielectric shielded power cable rated 5–35 kV, with tape shield, wire shield and UniShield® constructions.
Each kit contains sufficient quantities of material to make three single-phase terminations. The termination assemblies consist of a tubular insulator, high dielectric constant (Hi-K) stress control tube, conformable Hi-K stress controlling compound, and built-in environmental top seal. The insulator is made of a dark gray silicone rubber with advanced tracking resistant and hydrophobic properties. Note: Lugs need to be ordered separately. Exceptions: For T-150 Kits, 150 kV impulse level meets the impulse requirements for 35 kV class equipment where indoor terminations are used. 7620-T Kits are designed and assembled with stress controlling compound only.
