ABB UniGear ZS3.2 Metal enclosed Switchgear Panel for 40.5KV

ABB UniGear ZS3.2 metal enclosed switchgear panel is a metal-enclosed, three-pole air-insulated switchgear panels without disconnectors of UniGear ZS3.2 series are factory-assembled, type-tested indoor panels for a rated voltage of 36/40.5kv. They are designed as withdrawable module type panels, and fitted with a single busbar system. The withdrawable parts are fitted with vacuum circuit-breakers.

The panel consists of the following components:

1.Circuit-breaker compartment

2.Busbar compartment

3.Cabel connection compartment

4.Low voltage compartment

The compartments are separated from each other by earthed sheet steel partitions.
