China Supplier power distribution electrical Transformer Substation
Products meet GB17467-1998 "high and low voltage prefabricated substation" and IEC1330 standards. The voltage classes are applicable to 35KV and below, the small unattended substation, with main interior capacity of 2000KVA and below,
Functions:
The prefabricated substation can complete the transformation, distribution, transmission, measurement, compensation of electrical energy, system control and protection as well as communication functions.
Box substation, also known as Euripean Electric transformer /Box Transformer Substation , is made up of:
high-voltage switchgear,
low-voltage power distribution panel,
distribution transformer
and shell.
Main Characteristics :
- Suitable for long time outdoor use with guarantee of antisepsis,water proof, and dust proof
- The cabinet style transformer substation is a power distribution device composed of 3 parts : high voltage switchgear, power transformer,low voltage switchgear.
- compared with civil work style, it had advantage: great flexibility, small volume, small room occupation, low cost, rapid construction, high reliabilitiy, much more beautiful appearance.
Application place:
- widely used in urban power networkreconstruction, tall building, residential communities, industrial parks, commercial centers, airport, station and ports, schools, factories, etc
