10kV State Grid Replacement-type Prefabricated Metal Type Substation

A prefabricated high-voltage/low-voltage substation is a type of prefabricated substation that integrates high-voltage switchgear, transformer body, protective fuses in an oil tank, and low-voltage switchgear and corresponding auxiliary equipment.

It steps up the voltage output from the renewable energy grid-connected inverter (or AC generator) to 10kV or 35kV via a step-up transformer, and then transmits the electrical energy upwards through the corresponding voltage level lines to achieve grid connection. It is an ideal step-up device for renewable energy power generation systems.

Product Description

Product Overview

Our ZGS Box-Type Combined Transformer is a dedicated high-voltage/low-voltage (HV/LV) prefabricated substation engineered exclusively for new energy power generation. It integrates high-voltage switchgear, transformer body, protective fuses (housed within the oil tank), low-voltage switchgear, and auxiliary equipment into a single compact unit.

As a core step-up device for renewable energy systems, it steps up voltage from grid-tie inverters (or AC generators) to 10kV or 35kV, then feeds the power into the grid via transmission lines. This makes it the ideal solution for utility-scale solar and wind farms, ensuring efficient, stable, and secure grid integration.
