Outdoor Termination - Heat Shrinkable Moulded Shapes

Creepage Extension Skirt (Rain Shed) - INSULSHED
Outdoor termination

Insulshed is used to increase the surface creepage distance of the cores of outdoor termination without incressing the tail length. They are also used to avoid continuity during rainy season to avoid short circuiting of the elecrical network.

The rainsheds are made from high quality cross linked polyolefin material that offers exceptional non tracking behaviour, insulation and long term service reliabilty for indoor and outdoor applications. The creepage extension sheds are internally coated with water resistant mastic.
