Q:Could you please elaborate on the structure principle and operational advantages of the OLTC system?

A:3 phase 35kv 5000kva oltc power transformer is equipped with a high performance built in OLTC on-load tap-changing device. The voltage adjustment range covers ±8×1.25%, with an overall independent sealed oil chamber partitioned structure design.The voltage adjustment switching mechanism is equipped with a professional rapid arc extinguishing component.

3 phase 35kv 5000kva oltc power transformer can complete the voltage level switching adjustment while operating under full load without power interruption or shutdown, effectively avoiding power supply interruption losses caused by power off voltage adjustment. It can be operated electrically locally or be compatible with a remote automated voltage regulation control system.

Moreover, it can precisely correct the output voltage on the low voltage side according to the voltage fluctuations at the input end of the power grid, solving power supply problems such as line voltage drop and excessive voltage deviation in the power grid during peak and off peak periods, significantly improving the power supply quality of end electrical equipment.
