CLD SHRINK QT3 OUT SKIRT TERM 5KV 300-500 15KV 2/0-300 INS OD .72-1.29 3/KT

3M Cold Shrink Silicone Rubber Termination Kit QT-III, 7620-S, 7680-S and 7690-S Series contain one-piece, skirted, silicone rubber terminations, qualified as IEEE Standard 48-1996 Class 1 for outdoor weather-exposed applications. The termination assemblies consist of a skirted 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 dark gray silicone rubber with excellent tracking resistance and hydrophobic properties.
*7620-S and 7621-S 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 cables rated 5 through 34.5 kV, with tape shield, wire shield and UniShield constructions.

Applications

3M Cold Shrink Silicone Rubber Termination Kit QT-III, 7620-S, 7680-S and 7690-S Series are used to terminate tape shield, wire shield and UniShield power cable rated 5 - 34.5 kV, having extruded solid dielectric insulation as follows:

Polyethylene (high and low density), cross-linked polyethylene (XLP) and ethylene propylene rubber 9EPR)
The terminations are light weight for either free-hanging or bracket mounting arrangements.
They can be used in both protected and weather-exposed contaminated areas

The amount of airborne contamination determines the operating environment. Operating environments are described as areas having varying degrees of airborne contaminant or pollution severity that may, or may not affect the long-term performance of terminations. These operating environments are defined as light, medium, heavy and extremely heavy variations of pollution severity. The appropriate termination selection depends on the system voltage and operating environment.

Features

• Conforms to the IEEE Standard 48-1990 Class 1 requirements for 5, 8.7, 15 25/28 and 34.5 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)
