35KV Indoor Meta l- Clad Modular Switchgear ,Drawable Type , Air Insulated
Product feature:
It is a metal-clad type of switchgear, and it consists of two components, one is main body welded by sectioned steel and bent steel plate and another component is truck. It is the latest self-designed and developed version of switch by introduction of advanced technology in domestic and abroad. With advantages of a smaller size, a big breaking current, easier installation, a long-free-maintenance duration, this kind of switchgear has characters of easy operation and maintenance, safe operation, five-protection function and inter-lock capacity, etc as well.
