Electrical laminated wood is widely used as insulation and supporting materials in transformers and instrument transformers. It has many virtues such as moderate specific gravity, high mechanical properties, easy vacuum drying, no bad inner-reaction with transformer oil, easy mechanical processing, etc. The dielectric constant of this material is close to transformer oil, so it makes a reasonable insulation match. And it can be used in the transformer oil of 105℃ for a long time. People usually use this material to make upper/lower pressure pieces, cable supporting beams, limbs, spacer blocks in oil-immersed transformers, and clamps in instrument transformers. It replaced steel plates, insulating paper sheets, epoxy paper sheets, epoxide woven glass fabric lamination in these fields, and cut down the material expenses and weight of transformers.

The butterfly valve is usually installed between the oil tank and radiator of oil-immersed transformer to control oil flow between oil tank and the radiator of transformer. It is used to open or close the transformer oil circuit when vacuuming oil injection and transformer operation and maintenance. It can also be used in oil discharge in accidents or in maintenance.

The transformer cooling radiator is a device to rerlease that heat generated by the loss of the transfromer in operation to ensure the safe operation of the transformer . It’s a main transformer Accessory in power transformer. There are many kinds of center spacing of fin radiator like: 500mm, 625mm, 750mm, 1000mm, 1250mm,1500mm etc, with width 310mm, 480mm,520mm etc . We can customized all the type according to your requirements.
