The splicing kits have a high degree of mechanical strength for physical protection of connections and provide moisture-resistant insulation in above ground or direct buried applications. M Heat Shrink technology provides long-term, reliable performance as well as mechanical and environmental protection. Heat Shrink technology combines easy handling and installation with maximum operating reliability and system protection. With the application of heat. This EPDM rubber compound also provides superior electrical and temperature stability.
Insulators are factory assembled onto removable, collapsible cores.
No tools, torches, heat, mastic or mixes are required. 3M insulators resist punctures, fractures, moisture, alkalies, ozone and UV rays. Use the 8420 insulators for secondary splices, above ground and direct buried. The silicone tubes are pre-stretched onto a core that, when removed, allows the Cold Shrink tube to instantly shrink around the connection, tightly sealing it. No heat or flame is required, thereby eliminating costly standby fire safety measures for routine electrical maintenance work.
