3 Phase Pole Transformer

3 phase pole transformer

Column mounted transformers are key equipment used for voltage conversion and energy distribution in power systems, typically installed on 10-15 meter poles.Multiple windings can also be used to output different voltages. Three independent windings, connected in different ways ,such as star or delta, are used to input three-phase AC power and output the same.

1. Highly isolated;
2. N-G has good performance;
3. Highly common mode interference suppression;
4. Convert △ to Y or Y to △;
5. The voltage tap is easy to switch;
6. Design according to the special performance requirements of users.

Its core structure includes high-voltage terminals, insulators, heat dissipation devices, and protective components, and is equipped with protective devices such as vacuum circuit breakers and lightning arresters

Urban and rural power distribution: adapted to light commercial loads and industrial lighting needs, single-phase structure can shorten the transmission distance of low-voltage lines by 35%
Emergency power supply: In 2018, Shanghai Pudong applied mobile box transformer technology to replace a single transformer and increase power supply by 126000 kWh
Special environment: Suitable for tunnel areas where large cranes cannot enter, with a minimum working space requirement of 2.5 meters in height

What's the difference between a single-phase and a three-phase transformer?

Three phase transformers are much more efficient for industrial applications. Single phase transformers are most commonly used in residential settings for heating, air conditioning, lighting and home applications. They are less productive when it comes to high-power industrial machinery and systems.
