3M 7694-S-4 Cold Shrink Termination Kit Medium Voltage Accessories 0.83

Application:

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 kits are designed for terminating solid dielectric shielded power cable rated 5–35 kV, with tape shield, wire shield, and UniShield® constructions. 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 resistance and hydrophobic properties. 7620-T and 7621-T are designed and assembled with stress-controlling compounds only. The complete assembly is pre-stretched and loaded onto a removable core. The disposable core can be recycled.

Also known as:

3M 7694-S-4 Cold Shrink Silicone Rubber, 3M 7694-S-4 Medium Voltage Accessories, 3M 7694-S-4 silicone rubber terminations, 3M 7694-S-4 non-skirted terminations, 3M 7694-S-4 silicone sealing compounds, 3M 7694-S-4 common solid dielectric insulations

Details:

• These terminations can be filed-tested by using normal cable testing procedures.
• Provides a void-free seal to tape shield, wire shield, and UniShield® power cables.
• Switchgear, transformer, motor lead, bus, and similar connections.
• One-piece versatile design, allowing quick installation and accommodating a wide range of cable sizes
• Non-tracking, molded, silicone rubber insulation offers durability
• 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
• Silicone rubber insulators, EPDM stress control tubes, stress controlling compounds, and silicone sealing compounds are compatible with all common solid dielectric insulations, such as polyethylene (PE), cross-linked polyethylene (XLPE), and ethylene propylene rubber (EPR)
