Product Overview
A 1000 kVA Compact Substation—also known as a Packaged Substation or Unitized Substation—is a fully enclosed modular unit that integrates a 1000 kVA distribution transformer, medium-voltage switchgear, and low-voltage distribution panel within 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.
