¡ô10kV Characteristics of the products.
¡¡¡¡¡ó We have adopted the advanced finite element method analysis software in the world to ¡¡carry on the optimization design the structure , parameter of In-door and out-door ¡¡termination for 10kV and 35kV, which made the inside , outside insulating axle , radial ¡¡electrical field distributing in ideal state
¡¡¡¡¡óThere is no lengthways parting line which Solve the problems form former product ¡¡structure like vertical parting line easy to pile up , absorb the dust , impurity to parting line ¡¡place when operating for a long time completely. the machinery , electric performance ¡¡become to worse where the place of products lengthways parting line, Especially in moist ¡¡state or rainy day. It is easy to form conductive throughout pass-ways along lengthways ¡¡parting line,which lead to the fact products is it hold in place with a net to flashover , ¡¡influence cable safety factor , circuit of normal running.
¡¡¡¡¡ó The product increases the pressure on the surface between silicone rubber terminations ¡¡and cable semiconductor shield.£¬improved the steady performance and seal waterproof ¡¡result of the products.
