Compact pre packaged substationBasic Introduction

This instruction specifies the model description, environmental conditions, technical parameters, product structure, inspection, and labeling of CJ-XB series compact box type substations (hereinafter referred to as box type substations).

This technology is commonly used in CJ-XB box transformers with a rated frequency of AC 50Hz, a rated voltage of 10/0.4kV, and a transformer capacity between 50-1600kVA.

A box transformer is a compact power distribution device composed of high and low voltage switchgear, distribution transformers, energy metering equipment, and reactive power compensation devices assembled in one or several boxes.

Box type substation investment sites have a small footprint, short construction period, convenient maintenance, safety and reliability, especially their diverse appearance that is easy to coordinate with the surrounding environment. They are widely used in high-rise buildings, residential communities, factories and mines, municipal engineering, parks, shopping malls, etc., and are currently being vigorously developed.

　　Compact pre packaged substationTechnical Specifications

The grounding grid can be constructed using other methods, but the grounding resistance must be less than 4 ohms.

The number and location of pre embedded cable conduits are determined by the user.

Wall skirt, customizable steps.

Under the guidance of the local power supply department, cable head fixing brackets can be pre embedded.

Waterproof mortar with a thickness of 20mm.

Set the orientation according to the floor plan, with the transformer room door facing the roadside or open area.

The need for seepage holes is determined by the local groundwater level, and the user automatically determines it.
