Drum Tap Changer 
We are one of the well-known manufacturers and exporters of Series Parallel Connection for Tap Changer. The offered series parallel connection for tap changer is widely used in the networks, which are connected with multiple galvanic coils. Our manufactured series parallel connection for tap changer is capable of getting arranged in either series or parallel networking. The exported series parallel connection for tap changer is available at very reasonable market rates.

We are offering Reversing Type Off Circuit Tap Changer. When total tap turns are large or in special applications, reversing taps are useful to reduce total tap turns to half. Reversing type tap changers are used in special applications. This reduces the size of the tap changer as compared to the bridge or selector type tap changer of the same specification.

This type tap selector is one of our typical products. The series of this product is applicable to many kinds of oil immersed transformers with rated voltage 220KV and below as well as rated current 3000A and below. The effective number of turns of transformer coil can be changed by changing tap-changer position when the transformer is in non-excitation status, so to change transformation ratio, adjust and stabilize output voltage.

With simple appearance, small size of installation, flexible installation method, strong operation handle, automatic homing of contact, reliable touch, hard to operate wrongly, simple connection between switch and transformer, uniform electric field distribution, flexible layout, the transformer is easy to be miniaturized.
