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.

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.
