Main Features

1. High mechanical strength : the tensile and bending strength of the epoxy glass lead rod is 2 times higher than that of ordinary steel and 8 to 10 times that of high-strength porcelain material, which effectively improves the reliability of safe operation .
2. Good pollution resistance : its wet withstand voltage and pollution withstand voltage are 2~2.5 times of the same climbing distance porcelain insulator, and do not need cleaning, can operate safely in heavy pollution areas .
3. Strong environmental adaptability : stable performance in the ambient temperature of -60 degrees to +200 degrees, the use of non-disruptive design, no need to measure zero value in operation.
4. Easy installation and maintenance : compact structure, light weight, easy to transport and install, suitable for narrow corridors and urban network technical transformation .
