Detailed Product Description
YJJJI(T)-33kV XLPE Cable Cold Shrink Insulation(Straight) Joint
1.Scope:
The product is suitable for the connection of 33KV XLPE cable with the cable section of 25-1600mm2. The long-term operating temperature,
Max. allowance temperature and current capacity is satisfied with the requirement of fitting cable. The performance is satisfied with the requirements of IEC60502JB8144.
The insulation unit is made of high-property cold shrink silicone rubber insulation. The joint have outer enclose made of high-strength copper, the two copper enclose is separated by epoxy insulation ring, and ground separately by coaxial cable. It has advantage of good mechanical protective and good sealing perforance.
