8420 Series insulators are open ended tubular rubber sleeves. Factory expanded and assembled on a removable core they are supplied for field installation. Once positioned for installation the core is removed allowing the tube to shrink and create a waterproof seal.

Features and Benefits:

• Easily installed
• Suitable for various cable sizes
• Torches or heat not required
• Good thermal stability
• Tight seal
• Resilience and pressure remain consistent after years of ageing and exposure
• Excellent wet electrical properties
• Tough rubber formulation
• Waterproof
• Fungus resistant
• Acid and alkalis resistance
• Ozone and ultra violet light resistance

Applications:

• Primary electrical insulation for all solid dielectric insulated wire (rubber and plastic) and cable splices with 1000 V rating
• Direct burial or submersed
• Indoor, outdoor or overhead use
• Provides physical and moisture sealing protection for high-voltage air insulated connectors and lugs. Examples - Spacer cable and lug connections to busbar
• Secondary splice copper or aluminium conductor insulation
• Service relocation

3M Cold Shrink Tubing, 6.1mm Shrunk Diameter, EPDM Rubber Material - 8420 Series - 804130

Don't leave your connections exposed to the elements – with this 3M cold shrink tubing, you can create a secure seal. Its open-ended, tubular construction comes pre-stretched on a temporary core. When the core's removed, the tubing shrinks from an inner diameter of 23.9mm to a shrunk inner diameter of 6.1mm. This creates a strong covering that's resistant to water, chemicals and UV rays, keeping your conduit couplings safe. The tubing insulates cable splices and wires rated to 1000V, making it a reliable choice for high-powered installations.

Features & Benefits

• Robust EPDM rubber material stands up to wear, so you get long service
• Performs without a hiccup in a temperature range between -40°C and +90°C
• No torches, heat or special tools are needed for installation

Applications

• Wind power installations
• Mechanical engineering
• Telecommunication systems

How long is this tubing?

It's 203.2mm long, making it handy for covering joins, with no need for trimming.
