1 kV / 10 kV composite insulating heat shrink tape for cable repair, 25 mm wide
A composite tape of heat shrink backing and hot-melt adhesive. When heated to the backing's shrink temperature, the inner layer melts, sealing and insulating the protected live part in one step. Easy to apply, highly practical and compatible with other insulating materials.
Standard colours: black, red, yellow, green
