Central Point Round Tap Changer
A central point single phase round off load tap changer tap changer is a mechanism in transformers which allows for variable turn ratios to be selected in discrete steps. Transformers with this mechanism obtain this variable turn ratio by connecting to a number of access points known as taps along either the primary or secondary winding. These systems usually possess 33 taps (one at central "Rated" tap and sixteen to increase and decrease the turn ratio) and allow for ±10% variation (each step providing 0.625% variation) from the nominal transformer rating which, in turn, allows for stepped voltage regulation of the output.

We have reached more than 30 series and 5000 sorts of specification group. We can satisfy the requirement of tap changer used the voltage of 110KV and less than 220KV transformer. We can also undertake designing and making all kinds of special switches according to the technical parameters, special structure and quality required by the customers. The company focuses on product quality and has an independent production line which has adopted 3 units of international advanced level machining center equipment, 30 units of CNC lathes, 50 sets of instrument lathes and ordinary lathes, 10 units of wire cutting machines, 10 units of CNC milling machines and 28 units of stamping and injection molding equipment.
