10KV miniaturized intelligent pre-installed substation is our company’s experience in combining and optimizing advanced technologies at home and abroad. It integrates 10kV high-moon jade cabinets, transformers, transformers, low-voltage switches, reactive power automatic compensation systems, communication systems, protection systems, UPS power supplies and indicator meters into a sealed, moisture-proof and rust-proof double-layer box. It is a 10kV power distribution system secondary integration outdoor device. It is a new generation of intelligent substations that the State Grid focuses on promoting. It has the advantages of safety and reliability, small footprint, compact construction, miniaturization, and saves floor space compared with ordinary European transformers. The iron core adopts intelligent lamination process, which has the advantages of short lifting cycle, small and exquisite appearance, long service life, no radiation, low noise, and flexible layout. Through the optimization design, the process level is higher, the no-load loss and noise are reduced; the coil adopts an approximate elliptical structure to improve the anti-short circuit ability; the monthly microcomputer protection and integrated automation system are adopted to achieve “five remote and multiple guarantees”. The densely populated areas in the city are quickly accepted by the majority of power supply departments and users, and the market prospect is quite broad. This product is mainly used in commercial centers, industrial parks, residential quarters, streets, airports, docks, stations, subways)
