Prefabricated Box Substation

The box - type substation, also known as pre - assembled substation or pre - installed substation. It is a kind of factory - prefabricated indoor and outdoor compact power distribution equipment in which high - voltage switchgear, distribution transformers, and low - voltage distribution devices are arranged as a whole according to a certain wiring scheme, integrating functions such as transformer step - down and low - voltage power distribution organically together, and installed in a moisture - proof, rust - proof, dust - proof, mouse - proof, fire - proof, theft - proof, heat - insulated, fully - enclosed, and movable steel - structure box. It is especially suitable for urban network construction and renovation, and it is a brand - new substation that has emerged after the civil - construction substation. The box - type substation is suitable for mines, industrial enterprises, oil and gas fields, and wind power stations. It replaces the original civil - construction power distribution rooms and substations, becoming a new type of complete power transformation and distribution device.

Features and Applications

1. High - voltage switchgear, transformer, and low - voltage switchgear are integrated into one unit, highly integrated.

2. Perfect high and low - voltage protection, safe and reliable operation, simple maintenance.

3. Less floor space, low investment, short production cycle, convenient to move.

4. Flexible and diverse grounding schemes.

5. Unique structure: The double - layer (composite panel) shell with a unique honeycomb structure is firm, insulated, and well - ventilated for heat dissipation, beautiful, and of high protection level. Shell materials can be selected from stainless - steel alloy, aluminum alloy, cold - rolled plate, color steel plate, tiled, wood - sticked, new environmental - friendly materials, and surface watercolor painting.

6. Diverse types: general type, villa type, compact type, and other styles.

7. The high - voltage ring main unit can be equipped with a feeder automation terminal (FTU) to achieve reliable detection of short - circuit and single - phase ground faults, with "four remote" functions, facilitating the upgrade of distribution network automation.

Box - type substations are applicable to residential communities, urban public transformers, busy downtown areas, construction power sources, etc. Users can select box - type substations according to different usage conditions and load levels. Since their introduction, box - type substations have developed extremely rapidly, accounting for 70% of distribution transformers in developed European countries and 90% in the United States.
