product description

Feature of On-Load Voltage Regulating Oil-Immersed Power Transformer

This series of on-load voltage regulating oil-immersed power transformers strictly implement the National "Technical Guidelines for Power Systems", and can directly supply power to the power supply center. With the premise of achieving on-site balance of reactive power partitions, the regional load increases or decreases, the products cooperate with the switching of parallel capacitors and low-voltage reactors of reactive power compensation equipment and adjust the taps, so as to ensure the voltage quality of the power supply to users at any time. In addition to small-capacity transformers use layer coils, large-capacity transformers use continuous coil structures for high and low voltages. The longitudinal capacities of terminal are well distributed, effectively improving the voltage at the ends, balancing the distribution of ampere-turns,as well as having low magnetic leakage, high mechanical strength, and strong ability to withstand short-circuits. The transformer body and the general assembly are vacuum-dried and vacuum- oiled in order to fully guarantee the transformer's electrical property.
