Nanjing Electric Insulators puts their trust in SORG
Nanjing Electric Insulator is the largest producer of electrical insulators for high-voltage transmission lines in China. The insulators produced are subject to a very tight glass chemistry specification, which is different for direct current (DC) and alternating current (AC) insulators. With an article weight of up to 12kg, extreme demands are placed on the glass in terms of homogeneity, melting relics and inclusions from unmolten batch particles and seeds. Later failures of the insulators are not permitted.
