66-220kV Prefabricated Joint


The integral premoulded joint consists of a high-voltage electrode, two stress cones and insulators, and it is pre-fabricated by using high-quality silicon rubber in the factory. It can be installed only by pulling the spiral ring in the field construction after the preset bore-expanding process in the factory. A safe and stable surface pressure can be achieved by using the elasticity of the silicon rubber.
According to customer requirements, a coffin box can be used optionally. A premoulded joint without coffin box can also meet waterproof requirements due to its protective copper tube with plastic waterproof coating.
