Introduce:

SFSZ9 Type 110 kv level-63000kva,6300kva three winding high voltage transformer is manufactured in conformity with the International Electrotechnical Commission standard IEC60076 and PRC National Standard GB1094.1.2-1996, GB1094.3.5-2003, frequency of 50 Hz, and they can be used as the power transmission and transformation of power grid for various industries.

Features:

This product has the characteristics of excellent impact resistance, good mechanical properties, strong anti-short circuit ability, low partial discharge, low noise, low loss, good sealing, less maintenance, etc.

How does a transformer work
Transformer is the conversion of AC voltage, current and impedance devices, when the primary coil through AC current, the iron core (or magnetic core) will generate AC flux, so that the secondary coil induced voltage (or current). A transformer consists of an iron core (or magnetic core) and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary coil, and the rest is called the secondary coil. In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a fixed coil, the potential can be induced in the coil. In both cases, the value of the flux is unchanged, but the number of the flux intersecting the chain with the coil is changed. This is the working principle of the transformer. A transformer is a device that uses electromagnetic mutual inductance to transform voltage, current and impedance.
