YJZWC4/YJ series 64/110kV porcelain sleeve oil filled outdoor terminalDetailed product description：

YJZWC4/YJ series 64/110kV porcelain bushing oil filled outdoor terminal model:

YJZWC4/YJ  
Product features:
1. The porcelain sleeve is made of high-strength inorganic material electric porcelain, which has good weather resistance, leakage resistance, electrical corrosion resistance, and hydrophobicity.  
2. The raw material of the stress cone is high-performance imported liquid silicone rubber with high elastic deformation and low permanent deformation rate, ensuring that the stress cone can continuously maintain the clamping force on the cable mating interface during production and operation;  
3. Adopting a multi-layer sealing structure to prevent water and oil leakage of the ceramic sleeve during the operation of the terminal, and to improve the service life of the terminal.  
4. The installation of stress cones adopts cold shrinkage pre expansion technology, which is convenient and fast to install.  
5. All performance indicators of the product fully comply with GB/T11017 and IEC60840
6. 100% factory testing, stable quality
Product Applicability:
This product is suitable for outdoor termination of cross-linked power cables with a rated voltage of 64/110kV and a standard cross-section of 240mm2-1600mm2. It can be used in large chemical, steel, power generation enterprises, coastal areas, and areas far from urban centers with ambient temperatures ranging from -40 ℃ to+60 ℃. The insulation level, current carrying capacity, operating temperature and other performance of the terminal can fully meet the requirements of the compatible cable
