Transformer Filter Machine-Chongqing Tongrui Filtration Equipment Manufacturing Co., Ltd.

Why to choose the oil purifier?

When the transformer is working, a large amount of heat and arcs will be generated, and the transformer oil needs to be insulated and dissipated to assist in monitoring the operating status of the transformer. Transformer oil is the main insulating and cooling medium of oil-immersed transformers. Its electrical strength and chemical composition directly affect the performance of transformers. If the oil contains a small amount of moisture and impurities, the dielectric strength will be reduced; and the oil will be easily oxidized and deteriorated in contact with oxygen at high temperatures. Therefore, the transformer oil should be filtered by transformer filter machine when the transformer is installed.

Product Description

ZJA is double stage vacuum transformer filter machine, which contain vacuum pump and roots pump. We can do more big capacity of machine, and the smallest one is ZJA-30, 1800L/H, The biggest one is more than 30,000L/H. The machine is adopted the rustproof and moisture film and wood cases packages. We can take special order for you, like the machine face, color, weight, size, filter precision, filter numbers, spare parts, oil specification tester, etc.

Special attention online-use items:

1) Online work must be carried out on sunny days;

2) The connection of the inlet and outlet oil pipes must be carried out under the on-site commａnd of the electric engineer;

3) The transformer filter machine must have good performance (heating function, vacuum function, filtering system) before on-line work.
