Product Overview
A1000 kVA Compact Substation—also known as aPackaged SubstationorUnitized Substation—is a fully enclosed modular unit that integrates a1000 kVA distribution transformer,medium-voltage switchgearundlow-voltage distribution panelwithin a single weatherproof enclosure. Designed for fast deployment, space efficiency, and operational safety, this type of substation is ideal for urban, commercial, and industrial applications.
It provides a safe and reliable interface between medium-voltage (typically 11kV or 22kV) and low-voltage (400V) networks.
