Secondary Unit Substation

2026年6月26日Low Voltage Product 8440

Overview

Secondary Unit Substation is a complete integrated power distribution solution designed to receive medium-voltage power, transform it to low voltage, and distribute it safely to downstream electrical loads. It normally combines medium-voltage switchgear, a distribution transformer, and low-voltage switchgear or switchboard into one coordinated system.

Product Advantages

Complete Integrated Power Distribution SolutionThe Secondary Unit Substation integrates medium-voltage switchgear, transformer, and low-voltage distribution equipment into one coordinated system.

Compact Design and Space SavingThe integrated layout reduces the space required for separate electrical equipment.

Reliable Medium-Voltage Protection and ControlThe medium-voltage section can be equipped with MV switchgear, load interrupter switchgear, or metal-clad switchgear according to project requirements.

Efficient Voltage TransformationThe transformer section converts medium-voltage power to low-voltage power for downstream distribution.
