Detail
The distribution transformer is one of the important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings. It reduces the 10 (6) kV or 35kV network voltage to the 230/400V bus voltage used by users. This type of product is suitable for AC 50 (60) Hz, with a maximum rated capacity of 2500kVA for three phases
The S20-M.ZT on-load automatic capacity-regulating distribution transformer is a specialized transformer featuring dual-rated capacities (large and small).It employs an automatic capacity-regulating controller to continuously monitor and analyze the user's load demand.Through a specially designed on-load capacity- switching mechanism,it automatically switches between the two capacity modes without power interruption, enabling real-time adjustment of operational capacity and achieving automatic transition between the two rated capacity modes.This transformer is particularly suitable for rural grid modernization projects,as well as residential communities with significant day-night load variations and commercial/industrial facilities operating primarily during daytime hours.
