1. General introduction:
Transformer is made by high quality of material and advanced workmanship of technology.
This series of transformer not only have the ability to adjust the pressure, but also can isolate the three times of harmonic produced by power grid to equipment and protect to reduce the fever produced by machine and the lifetime of Insulation materials. They can be equipped and used directly on load of different natures and can be used in the work sites that Utility the voltage needs to be change or isolated safely.
These parameters or parts of transformer including input and output voltage (Single-phase, three-phase, more ways of input and output etc),the distribution of volume of Quad tap, outside case (equipped or not) can be designed and produced elaborately according to the requests of clients.
2. Features:
Function of voltage transformation(For example:Y/ Y or Y/triangleConnection) Have Anti-interference function with the filter(For example: Can remove the third harmonicwith heat resistance, moisture resistance, stability, Chemical compatibility, temperature resistance, environmental protection, radiation and toxic properties.
