Product Description

Product Description

    DNF7 metal-clad switchgear is constructed by aluminum-zinc sheet metal in a double bending process and riveting fixing technology, to form an extremely rigid construction DNF7 is assembled by means of the riveting nuts, high strength bolts and steel core rivets connection, and no holes are needed between panels to make installation

easy, improve the production efficiency. DNF7 metal clad switchgear consists of four separated compartments, including Busbar compartment, Circuit Breaker compartment, Cable compartment and Low voltage compartment, and it is a LSC2B service continuity, PM partition class switchgear.
