As a result, the transformer has a regulating or tap winding that is connected to the OLTC. The main components of these transformers are contact systems for the make and break currents, as well as spring energy accumulators, and a drive mechanism are the main components of an OLTC. Our on-load tap changer features an integrated design, transition resistors, and liquid insulation. The product is used to change transformer taps under the workload and adjust the output voltage. The transformer on-load tap changer has a diverter switch and tap selector. These transformers have a compact design that ensures space saving. Our OLTC transformers are built to meet the highest operational parameters and industry standards.
