YD series testing transformer

Testing transformer mainly used to produce high voltage AC power supply, characterized by a low voltage winding with last unit voltage regulator, from zero make a smooth continuous adjustment to any scheduled voltage. In the use of various occasions, running time is not the same, the running time changes between short time operation and long time operation, rated output capacity of short time operation mode is much bigger than continuous operation. Testing transformer (is made of iron as a case) uses iron shell as shell, high voltage output end using electrical porcelain annular tubes and high strength compound insulation casing pipe, it is the preferred equipment for ordinary withstand voltage testing.
