66~110kV Porcelain Sleeve Type Outdoor Terminal
Description
Product Features
High strength porcelain bushing, high mechanical strength, good stability, not aging, especially suitable for coastal and bad natural environment area.
Use a umbrella skirt size and structure, proved its excellent resistance to fouling.
Special seal structure design, sealed performance is good, put an end to the possible defects such as flooding, the oil spill.
Porcelain: there are two kinds of size 1280 mm high, the creepage distance is 3150 mm, used in leve III polluted area; 3906mm, 1400 mm high, its creepagedistance is suitable for the level IV polluted area;
Main insulation parts in the factory according to the regulations of the standard after testing.
Products Comply With The Following Standards
GB/T 11017.3-2014 Power cables with cross-linked polyethylene insulation and their accessories for rated voltage of 110kV (Um=126kV). Part 3: Accessories
IEC 60840-2011 Power cables with extruded insulation and their accessories for rated voltages above 30kV (Um =36kV) up to 150kV (Um=170 kV). Test methods and requirements
