| High voltage transformers manufactured by Dibao reach 15000V and are airproofed with high voltage epoxy resin ,which enable their high isolation ability.Three Phases Transformer manufactured by Dibao are mainly classified three phase C-core transformer and three phase R-core transformer. Toroidal transformer are also can be assembled as three phase transformer. These sort of transformers enjoy the characteristics such as high efficiency, low temperature rise and low loss .Autotransformer has great advantages of small-size, low cost and high efficiency. The adjusted ratio in voltages of audiotransformer is lower than the usual transformer under the same situation, which becomes more obvious when the distinction between primary and secondary' s voltage becomes less obvious. Generally, the voltage ratio of autotransformer is rarely more than 2.Autotransformer's isolation much be designed based on high voltage for the connection of primary and secondary' s windings .But autotransformer can not be used as isolation transformer for the reason that they share the grounding point.Audio transformer is working in a wide frequency band ,for instance, they works at the range from 20HZ to 20KHZ .Yet power transformer is working in a fixed frequency such as 50HZ,60HZ,400HZ,etc.The leakage flux and distributed capacitance are key factors in the high-frequency point of audio transformer while they are needless to be taken into account in power transformer. So for audio transformer, it is necessary to reduce the leakage flux and distributed capacitance in designing the coils' construction.Waterproof Transformer has been treated with waterproof process and is classified into different grades according to their waterproof ability. Water proof transformer was mainly used in swimming pool ,pool, bath, outdoor lighting ,kitchen and the places where would touch the water. But the transformer must not be permanently submerged in water.Step Up Transformer, Step Down Transformer are usually used in the voltage match for the appliances |
