Product Advantage
1. Voltage conversion and energy transfer :
The core function of a distribution transformer is to change voltage. It can reduce high voltage to a voltage suitable for the
distribution network, and at the same time adjust the current to an appropriate level, thereby achieving effective transmission of electrical energy.
2.Improving power transmission efficiency and safety:
By reducing voltage, distribution transformers can reduce energy losses during power transmission, thereby improving
the efficiency of the entire power system.
