Prefabricated dry cable termination is made of stress cone and silicone rubber insulation material. The stress cone was designed and optimized by finite element analysis software, made of electrically conductive silicone rubber, it make the electric field distribution at cable shield port is improved and uniform reliably.
The external insulation of the composite cable termination is composed of a glass fiber reinforced epoxy resin tube and a silicone rubber rainshed, aluminum alloy flanges with strong corrosion resistance are installed at both ends. Compared with the traditional porcelain tubing, the composite tubing has many advantages, It is the best substitute for porcelain covers and has gradually been accepted all over the world.
Porcelain Sheathed Cable Termination is a important part of 110kV products. The main varieties of 110kV and above XLPE insulated cable termination are: Outdoor termination, GIS termination (installed in fully enclosed combined appliances) and transformer termination (installed in transformer oil tanks). Prefabricated Rubber Stress Cone Termination and Prefabricated Intermediate Joint are main type of high voltage crosslinked cable accessories used in China. Our 110kV series products meet the requirements of IEC60840 and GB/T11017.3, the product adopts special electric field analysis software to optimize the design, and they are made of high quality materials and advanced production technology, it ensures uniform electric field, stable performance and reliable operation.
