YJJT/ YJJJ 66-500kV Premoulded Joint






YJJT/ YJJJ 66-500kV Premoulded 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 core 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. The joint without coffin box (Dipping type) can also meet waterproof requirements due to its protective copper tube with plastic waterproof coating.
