Products are divided into single core, three core, has been widely used in 26/35kV cable terminal processing and intermediate connection. Long service life, exposed to the sun for 10 years, the material properties are basically unchanged. The product structure adopts professional software to calculate the electric field division, and fully considers the various factors in the actual application of cable accessories (such as stress cone deformation, interface characteristics change), after several optimization and advanced design, the electric field distribution is more reasonable, and the product safety is higher. Scope of application: High altitude area, cold area, wet area, salt spray area and heavy pollution area. And the installation does not use open fire, suitable for petroleum, chemical, tunnel and other flammable and explosive places.
