1. Overview
FV series on-load tap changers are suitable for power transformers or industrial transformers with a rated voltage of 35 to 110 kV, a maximum rated through-current of three-phases 200A, 350A, 500A, single-phase 200A, 350A, 500A, 700A, power transformers or industrial transformers with a frequency of 50 to 60 Hz, to change the tap under load to regulate the voltage.
This on-load tap changer is suitable for power or industrial transformers with a rated voltage of 35 to 110 kV, a maximum rated through-current of 500 A or less, a frequency of 50 Hz to 60 Hz, a three-phase, Δ(D) or Y-connected neutral regulating connection to change the transformer connectors to change the transformer's output voltage to achieve a stable voltage at the output end within a specified range under load conditions; or to increase or decrease the output voltage according to the requirements of the load to achieve the purpose of adjusting the voltage on the line.
