A transformer that is safe, flame-retardant, non-flammable, non-polluting, and directly installed at the load center can undertake various non-standard designs and productions according to the requirements of the design institute to help users save investment.

The low voltage adopts copper foil winding to make the electric field of the transformer evenly distributed. The inner frame of the low voltage adopts a molded hard paper tube. The compression pad adopts laminated wood to enhance the mechanical strength of the transformer. The transformer adopts vacuum oil injection, which can completely eliminate the bubbles in the coil and improve the electrical performance of the transformer. The box edge adopts stainless steel bolts, and the appearance is beautiful. A fully sealed fuel tank is adopted to isolate the transformer oil from the air and slow down the aging of the transformer oil. The sealing parts adopt molded parts to enhance the sealing reliability of the transformer. Combined with the oil-transformer terminal and intelligent terminal, by adopting power automation monitoring means and 4G communication technology, the purpose of real-time monitoring and wireless communication transmission can be achieved.

The high-voltage chamber of the European-style box transformer is generally composed of high-voltage load switches, high-voltage fuses, lightning arresters, etc., which can perform power on and off operations and has overload and short-circuit protection. The low-voltage chamber is composed of low-voltage air circuit breakers, current transformers, ammeters, voltmeters, etc.

The intelligent on-load automatic capacity and voltage regulating distribution transformer (referred to as the “capacity and voltage regulating transformer”) is mainly used in the distribution area with a rated voltage of 10 kV and a capacity of 630 kVA and below.

Raise the voltage generated by the wind power (photovoltaic) power generation device such as 690V (800V, etc.) to the 35kV voltage level and then input it into the power grid through the cable line. It is an ideal supporting equipment dedicated to the wind power (photovoltaic) power generation system.

Intelligent double-layer box-type substation is a new type of power distribution equipment. The transformer and low-voltage switch cabinet adopt a double-layer structure layout, which has high safety and reliability and can be widely applied in various fields such as cities, rural areas, factories, and mines. It has the advantages of small floor area, beautiful appearance, convenient installation, and small construction volume, which can meet the power supply needs of different places.
