High performance of weather aging resistance
For porelain insulator, the porcelain body connects with hardware fitting by cement
pouring, we use the (por-rok)ANCHORING cement manufactured by CGM INC from
USA. This kind of cement has rapid solidification, high mechanical strength, low
expansion coefficient and superior weather resistance.
For polymer insulator, the hardware fitting crimped onto fiberglass rod, material of housing and sheds manufacture of high-temperature Vulcanized Silicone Rubber, and the insulator moulded by one piece injection molding. It has good sealing performance and good performance of tracking and erosion resistance.
All ferrous parts processed by hot dip galvanized, its zinc coating more than 86u, it has
good corrosion resistance.
