YJZWCF4/YJ series 64/110kV composite casing oil filled outdoor terminalDetailed product description：

YJZWCF4/YJ series 64/110kV composite casing oil filled outdoor terminal

Model:
YJZWCF4 /YJ 

Characteristics:
1. It has all the advantages of a porcelain sleeve terminal.  
2. Has excellent mechanical properties, avoids the risk of explosion, and has excellent explosion-proof performance.  
3. Lightweight, with the same rated voltage, the composite sleeve weighs less than 20% of the weight of the ceramic sleeve, making it easy to load, unload, and transport, and highly conducive to installation and operation. A lightweight support structure can be used.  
4. Excellent stain resistance, UV resistance and good aging resistance.  
5. Silicone rubber has good hydrophobicity, and even if the surface pollution is quite severe, it is difficult for wet flash to occur.  
6. The upper and lower flanges adopt a circular arc structure to improve the electric field structure and avoid surface discharge.  
7. The installation of stress cones adopts cold shrinkage pre expansion technology, which is convenient and fast to install.  
8. All performance indicators of the product fully comply with GB/T11017 and IEC60840
9. 100% factory testing, stable quality
Product Applicability:
This product is suitable for outdoor terminal connection of cross-linked polyethylene power cables with a rated voltage of 64/110kV and a nominal cross-sectional area of 240mm2-1600mm2. It can operate in coastal and high pollution areas, and is suitable for use in urban centers, areas with dense equipment, and areas that require splash prevention. The terminal insulation level, current carrying capacity, operating temperature, and other performance fully meet the requirements of the matching cable.
