China Distribution Transformer Factory: Reliable Power Supply Solutions from Trusted Suppliers
Working Principle
The Distribution Transformer operates on the principle of electromagnetic induction. It consists of primary and secondary windings mounted on a laminated silicon steel core. When alternating current flows through the primary winding, it creates a varying magnetic field in the core, which induces a voltage in the secondary winding. The voltage transformation ratio is determined by the turns ratio between the primary and secondary windings. Typically installed on utility poles (pole-mounted) or at ground level (pad-mounted), these transformers are filled with insulating oil that serves both as a dielectric medium and as a coolant, dissipating heat generated by core and copper losses to maintain optimal operating temperatures.

Frequently Asked Questions
A distribution transformer works on the principle of electromagnetic induction. Alternating current in the primary winding creates a varying magnetic field in the laminated silicon steel core, which induces a corresponding voltage in the secondary winding. The ratio of output to input voltage is determined by the turns ratio of the two windings.
Insulating oil serves a dual purpose in a distribution transformer. It acts as a dielectric medium to provide electrical insulation between live components, and it also functions as a coolant by dissipating heat generated by core and copper losses, helping maintain safe and optimal operating temperatures.
Our distribution transformers are designed, tested, and manufactured in accordance with IEC 60076 and other relevant international standards. This ensures product safety, interchangeability with other grid equipment, and full compatibility with utility grid requirements worldwide.
Pole-mounted transformers are installed on utility poles and are typically used for supplying electricity to residential areas and rural communities. Pad-mounted transformers are installed at ground level on a concrete pad and are commonly used for commercial buildings, urban areas, and locations where overhead lines are not suitable.
Yes. Distribution transformers are widely used in grid-tied solar rooftop installations. They provide voltage matching between the photovoltaic array output and the utility grid, as well as electrical isolation to ensure safe and stable grid integration of solar energy systems.
A hermetically sealed tank prevents external air, moisture, and contaminants from entering the transformer. This protects the insulating oil from oxidation and degradation, significantly extending the transformer's service life and reducing maintenance requirements, making it ideal for long-term, trouble-free operation in various environmental conditions.
