Model:U70B
You can rest assured to buy Anti Pollution High Voltage Power Line Toughened Glass Insulator from Jecsany factory and we will offer you the best after-sale service and timely delivery. Due to the high mechanical strength of the surface layer of the glass insulator, the surface is not prone to cracks. The electrical strength of glass generally remains unchanged throughout the operation period, and its aging process is much slower than that of porcelain, so glass insulators are mainly scrapped due to self-damage, which occurs within the first year of operation, but the defects of porcelain insulators are only after a few years of operation. began to be discovered years later.
Wholesale low price Anti Pollution High Voltage Power Line Toughened Glass Insulator made in China. Jecsany is a Anti Pollution High Voltage Power Line Toughened Glass Insulator manufacturer and supplier in China. IEC 60120 70KN Suspension glass insulator not only have a delicate appearance and stable quality, but also support high voltage transmission lines. A suspension string can be made suitable for any voltage level.
