S11 type 10kV non-excitation voltage regulating distribution transformer

The power transmission and distribution system transfers the electric energy from the remote power plant to the user through regulation. The electric energy is transmitted through the high-voltage transmission line, and then can be suitable for the user after the voltage is reduced in several levels of substations. The distribution transformer located near the final power user will eventually reduce the voltage to the appropriate value. The transformer that reduces the voltage to the working voltage of electrical equipment is called distribution transformer. This type of transformer is used for daily lighting and factory power. Generally, the low voltage is 0.4kV and below. The capacity of distribution transformer is small, generally 2500 kVA and below, and the primary voltage is also low, all of which are 35 kV and below.
