15 to 0.4kv Power Transformer 400 Kva

This 15 to 0.4kv power transformer 400 kva has a rated capacity of 400 kVA. The design of the rated load is reasonable, the power supply output is balanced, the carrying capacity is excellent, it can meet the demand for short term overload operation, easily cope with the load changes during peak electricity consumption periods, and effectively avoid faults caused by unbalanced three phase loads.

The 15 to 0.4kv power transformer 400 kva uses high quality iron cores and optimized winding technology, with low values of no load loss and load loss, outstanding energy saving effect, and can effectively reduce the operating power consumption cost over the long term.

Adopting an oil immersed self-cooling heat dissipation method,15 to 0.4kv power transformer 400 kva can achieve uniform and efficient heat dissipation, with reasonable temperature rise control. It can operate stably at full load for a long time. Combined with the Dyn11 connection group, it can effectively suppress grid harmonic interference, purify the power supply waveform, and better protect various electrical equipment.

By selecting high strength insulating materials and adopting a multi layer insulation protection design, the electrical gap between the high and low voltage windings and the core is isolated. As a result, the insulation performance of 15 to 0.4kv power transformer 400 kva is extremely excellent. The internal windings are tightly bound and fully reinforced, ensuring a stable mechanical structure that can withstand the huge mechanical stress generated by instantaneous large currents. Therefore, it has extremely strong anti short circuit impact capability, can effectively resist deformation and damage caused by sudden short-circuit currents, and significantly improves the operational safety coefficient.

The fully sealed oil tank is made through an integrated molding process, completely preventing the intrusion of external moisture, dust and corrosive gases. Therefore,15 to 0.4kv power transformer 400 kva possesses excellent waterproof, dustproof and corrosion resistant properties, and is suitable for various complex working environments. At the same time, the iron core is made of low loss high quality silicon steel sheets, with precise assembly process. During operation, the magnetic vibration and mechanical vibration are small, and the operating noise is lower.

In addition, the internal insulating oil is not prone to oxidation and deterioration, and the aging speed of internal components is slow. This results in a longer overall service life of the 15 to 0.4kv power transformer 400 kva, and there is no need to frequently replace the oil or repair internal components. Daily maintenance is also simpler and more convenient.
