Usage
Heat Shrinkable Creepage Extension Sheds are manufactured from High quality cross linked polyolefin material that offer exceptional no tracking behaviour, insulation an long term service reliability . The possess advantageous physical properties, excellent aging stability and very good resistance against chemicals. Due to its excellent combination of properties as an inbuilt character of the base polymer, find proven application in electrical segment of industries. The following are few typical application where these extension sheds are used As an integral part of Heat Shrinkable terminations upto 72 kv voltage class for Indoor & outdoor application where they provide extension to creepage path of the cable terminations. To provide extension creepage length and to avoid continutity during rainy season and to avoid short circuiting of the electrical net work as case to case bases as per system requirement.
