The designs are in line with GB, TB, ANSI, AS, IEC, and BS standards, as well as clients’ special requirements
Good mechanical properties under low temperature: a bending test demonstrates that, under a low temperature of -40 °C, the damage degree of our porcelain insulators shows little difference with those under a constant temperature state.
This insulator is mainly applied in the AC power lines of common or heavy contaminated areas with the voltage over 1000V, the frequency less than 100Hz, and the altitude within 1000m. The appropriate temperature for installing this sort of porcelain post insulator is -40℃~+40℃.
This series of products are commonly used in DC1500V overhead catenary system. They can be classified as rigid suspension insulator, cantilever rod insulator (JA&JB), anchor insulator, and feeder insulator, etc. The insulators for high speed rail are suitable for being installed with horizontal oblique cantilevers, with the drainage holes being mounted downward.
