Description

3M Cold Shrink Silicone Rubber Termination Kit QT-III 7620-T and 7690-T Series contain one-piece, non-skirted, silicone rubber terminations, qualified as IEEE Standard 48-1990 Class 1 for indoor and weather-protected applications.
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 silicone top seal. The insulator is made of a new dark gray silicone rubber with advanced tracking resistant and hydrophobic properties.
*7620-T and 7621-T designed and assembled with stress controlling compound only.
The complete assembly is pre-stretched and loaded onto a removable core. The disposable core can be recycled. The kits are designed for terminating solid dielectric shielded power cable rated 5 through 35 kV, with tape shield, wire shield and UniShield constructions.

Caractéristiques
  • Conforms to the IEEE Standard 48-1990 Class 1 requirements for 5, 8.7, 15 25/28 and 35 kV terminations
  • One-piece versatile design, allowing quick installation and accommodating a wide range of cable sizes
  • Cold Shrink delivery system for easy installation: simply place termination over prepared cable and unwind core to shrink into place (no force fit required).
  • Hi-K stress control: specially formulated high dielectric constant material minimizes surfaces stress by more uniformly distributing the electrical field over the entire surface of the insulator
  • Compact design provides for easier installation in restricted spaces
  • Silicone rubber insulators, EPDM stress control tubes, stress controlling compound and silicone sealing compound are compatible with all common solid dielectric insulations, such as polyethylene (PE), cross-linked polyethylene (XLPE) and ethylene propylene rubber (EPR)
Applications

Designed for:
5, 8.7, 15 and 25/28 and 35 kV voltage classes
Tape shielded, wire shielded and UniShield cables
Solid dielectric insulations, such as polyethylene, XLP and EPR
Contaminated and non-contaminated indoor (weather-protected) locations
Free-hanging or bracket-mounting arrangements
Upright or inverted installations
Switchgear, transformer, motor lead, bus and similar connections.
These terminations can be filed-tested by using normal cable testing procedures (reference: ANSI/IEEE Standard 400 "Guide for Making High-Direct-Voltage Tests on Power Cable systems in the Field").
