Cold Shrink Connector Insulators
These open-ended, tubular rubber sleeves are designed for protecting and insulating
solid dielectric insulated wire and cable but also provide excellent strain relief and
physical protection for wire harnesses.
They are factory expanded and assembled onto a core which is removed after the
tube has been positioned for installation over an inline connection or harness section.
The tube shrinks, forming a dynamic, environmental seal which resists prolonged
aging and exposure. It installs quickly with little training and no tools or heat source.
The 8420 series insulators are made of EPDM rubber. Six diameter sizes may
cover a range of 1000-volt cable to 10 AWG through 1000 kcmil.
The 8440 series insulators are made of silicone rubber and come in three sizes
which may cover an application range of 6 AWG to 3/0 AWG.
