Compact Substation

Description

A compact substation combines medium-voltage switchgear, a transformer and low-voltage distribution in an enclosed assembly. The published options cover medium-voltage systems up to 36 kV and transformer capacities up to 2500 kVA for local power distribution in urban infrastructure, industry and commercial developments.

Compact Substation — Key Features

• MV switching, transformation and LV distribution in one assembly.
• Oil-immersed or dry-type transformer configurations.
• Ring-network or terminal supply arrangements.
• LV distribution, metering and protection equipment.
• Enclosed layout reduces the need for separate equipment buildings.
