YBM High-Voltage Complete Transformer Pre-Installed European-Style Substation

Overview

European-style box-type substations(MV/LV Prefabricated Substations) arrange high-voltage, distribution transformers, low-voltage power distribution devices, and electric energy metering equipment into a compact power distribution device according to a certain circuit plan, with a small footprint.

The main technical parameters

Applicable place

It is suitable for urban public power distribution, high-rise buildings, living quarters, industrial and mining enterprises, oil fields and temporary construction of projects.

Function

It combines high-voltage electrical equipment, transformers, low-voltage electrical equipment, etc. into a compact complete set of power distribution devices, which are used in urban high-rise buildings, urban and rural buildings, residential quarters, high-tech development zones, small and medium-sized factories, mines and oil fields, and temporary construction electricity. The site is used for receiving and distributing electric energy in the power distribution system.

It has the characteristics of strong complete set, small size, compact structure, safe and reliable operation, convenient maintenance, and mobility. Compared with conventional civil substations, box-type substations with the same capacity usually occupy only 1/10 of the area of conventional substations. ~1/5, which greatly reduces the design workload and construction volume, and reduces the construction cost. In the power distribution system, it can be used in the ring network power distribution system, and can also be used in the dual power supply or radiation terminal power distribution system. It is a new complete set of equipment for the construction and transformation of urban and rural substations.
