Heat Shrink Rain Sheds

Heat Shrink Rain Sheds

Used to increase the surface Creepage distance of the cores of cable termination without increasing the length. They are also used to avoid continuity during rainy season to avoid shot circuiting of the electrical network. The rain sheds are made from high quality cross linked polyolefin material that offers exceptional non tracking behavior, insulation and long term service reliability for indoor and outdoor applications. The creepage extension sheds are internally coated with water resistant mastic

Material: High quality Cross Linked Polyolefin

Standard Color: Red
