Branching heat shrinkable fittings with two fingers are used for simple and fast insulation of cable branching points onto single cores. To ensure complete protection against corrosion, the fittings are available with a thermoplastic or epoxy adhesive coating. The heat shrinkable finger separators are made of resistant, crosslinked polyolefin containing flame retardant additives. This allows for the use of fittings both inside and outside, providing excellent mechanical and electrical protection. Finger separators are supplied with an internal adhesive coating for some environmental protection, in versions for cables with 2, 3, 4, 5, and 6 cores.
