Package transformer is divided into American type and European type.
Combined transformer (commonly known as American Package transformer or Package transformer), low loss, low noise, long service life. The Package type substation is mainly composed of multi-circuit high-voltage switch system, armored bus, substation integrated automation system, communication, sport, metering, capacitance compensation, DC power supply and other electrical units. It is installed in a moisture-proof, rust proof, dust-proof, rat proof, fire-proof, theft-proof, heat insulation, fully enclosed and movable steel structure Package, with electromechanical integration and fully enclosed operation.
There is an independent transformer room. Dry type transformer or oil immersed transformer is selected. High voltage switchgear, transformer and low-voltage switchgear are three in one with strong integrity. The box has five prevention functions, safe and reliable operation and simple maintenance. Less land occupation, less investment, short production cycle and convenient movement. The grounding scheme is flexible and diverse. Unique structure: the shell material can be stainless steel alloy, aluminum alloy, cold-rolled plate, tiling, environmental protection material, etc., which is firm and has good heat insulation and heat dissipation. The beautiful and generous appearance can be more coordinated and unified with the style of local buildings. The high-voltage side is generally protected by load switch and fuse combination apparatus. The load switch can be air compressor type, vacuum type, sulfur hexafluoride, etc., and can be operated by power distribution; the main switch at the low-voltage side is universal or intelligent circuit breaker, with selective protection. The switch selects molded case circuit breaker with many circuits and intelligent reactive power compensation device. It is widely used in urban power grid reconstruction, residential quarters, high-rise buildings, industrial parks, factories, temporary construction power, airports, oil fields, docks, expressways and other outdoor places.
Scope of application:
It is suitable for urban public power distribution, street lamp power, industrial and mining enterprises, urban construction, residential, mountainous area, hotel, park and construction site, etc. it can realize ring network and terminal power supply mode.
The package transformer products of the company have been sold to many countries and regions at home and abroad in the past 20 years. In 2016, the company cooperated with ZTE energy to export 20 American package transformers to Pakistan for China's first generation all the way project.
