8420 Series Cold Shrink Connector Insulators

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


• 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
