YB-12 0.4 Prefabricated Containerized Distribution Transformer

Product Introduction

YB-12/0.4 transformer distribution/ prefabricated substation

 

 

 

 

Product Description

 

YB series substation is a kind of compact power distribution device that integrates high voltage electrical equipment, transformer, and low voltage electrical equipment. It can be used in high-rise buildings, building in urban and rural areas, residential communities, high-tech development areas, small and medium-size factories. mining areas, oil fields, temporary construction sites, and other premises. It also can be used for acceptance and distribution of power in the power distribution systems of 6-15KV, 50HZ (60HZ), ring main power distribution system, and double power supply or radiate terminal power distribution system.

 

 

Product features

 

High integrity, small size, compact structure, safe and reliable operation, convenient maintenance, portable, etc. Compared with conventional civil-engineering substations, in the same capacity, the prefabricated combined substation needs only 1/10-1/15 floor area. So that the construction expense is reduced.

Installation

 

The manufacturer can provide the foundation layout for their modular substation. The customer or user can design the foundation by themselves, but the layout need to be provided for manufacturer.

The lightning conductors need to pre-lay in side or around of the foundation of the modular substation. The ground connection and lightning protection of the transformer can be jointly used as one grounding system. The grounding cables to the foundation platform should be not less than two lines and the grounding resistance should be guaranteed to be less than or equal to 4 Ohm.(R≤4Ω)

For water proof, the gap between the modular substation and the foundation should be sealed with the cement concrete.
