Description of ZN85G-40.5
36kv circuit breaker
ZN28 series vacuum circuit breaker as specified voltage 12KV, three-phase exchange 50/60 HZ high
pressure switchgear in the one. Products accord with GB1984 standard, this product ensemble architecture and operating organization an organic whole installer switch noumenon separates from operating organization and installs two kinds of forms for switch noumenon. An organic whole type structure Namely a basic model of ZN28, Divide style structure a ZN28A type, it should be in various kinds of regular type switch cupboards to be right, such as GG-1A(Z),
XGN2A10(Z),etc.
Product this can mix and speak with CD17, model CD 10A direct current magnetism motive construct speak and move organization with CT17, model CT19 spring energy storage type.

Our story with customers
In 2005,we received the email from ALIBABA that a Russian customer would like to order the KYN28-12 indoor metal-clad enclosed switcgear.We confirm the product parameters and pictures carefully again and again with the client,the last communication is the most difficult in price,it is a psychological warfare,customers began to demand a 20% cut,we insist on our price,emphasis on the various advantages of our products with the high quality. After compared with other factory,Russia customer finally chose to coperation with our company.After more than 20 days,customers sent a email to tell us that they are very satisified with the goods.
