Main features
1. Compact structure, fully sealed structure, safe and reliable, name maintenance, reliable protection of personal safety.
2. The high-voltage wiring can be used for both the ring network and the terminal. The conversion is very convenient and the reliability of the power supply is improved.
3. Excellent transformer performance: low noise, low loss, strong impact resistance, short circuit and overload resistance.
4. The car body can adopt anti-corrosion design and special painting treatment according to the requirements of the operating environment, and can meet the anti-corrosion requirements in high temperature and high humidity environments.
5. It is widely used in outdoor places such as urban power grid transformation, residential quarters, high-rise buildings, industrial parks, factories, temporary construction electricity, airports, oil fields, docks, highways, etc.
Overview
Box-type substation is also called prefabricated substation or prefabricated substation. It is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a factory-prefabricated indoor and outdoor compact power distribution equipment arranged according to a certain wiring plan. It organically combines functions such as transformer step-down and low-voltage power distribution. At the same time, it is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, and movable steel structure box. It is especially suitable for urban network construction and transformation. A brand new substation. The box-type substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil power distribution rooms and power distribution stations, and becomes a new type of complete set of power distribution devices. Box-type substations are suitable for residential quarters, urban public transformers, bustling downtowns
