The 225kVA Three Phase Pad Mounted Transformer is a compact, reliable, and energy-efficient outdoor distribution transformer designed for medium-voltage power distribution applications. It is widely used in utility networks, commercial buildings, industrial facilities, renewable energy projects, and infrastructure developments.
Installed on a concrete pad with a secure weather-resistant enclosure, the transformer provides safe and efficient voltage conversion from medium voltage (MV) to low voltage (LV). Compared with traditional pole-mounted transformers, the pad mounted design offers improved safety, easier maintenance, lower visual impact, and better protection in urban and industrial environments.
Manufactured with high-quality electrical materials and advanced production technology, the 225kVA three phase pad mounted transformer delivers stable performance, low power losses, excellent insulation performance, and long service life. The transformer can be customized according to different grid standards, environmental conditions, and EPC project requirements.
The 225kVA Three Phase Pad Mounted Transformer adopts an oil-immersed design with ONAN (Oil Natural Air Natural) cooling. The transformer body is installed inside a robust steel enclosure that protects the internal components from moisture, dust, corrosion, and external impact.
The transformer core is manufactured using high-grade grain-oriented silicon steel, optimized to reduce magnetic losses and improve operating efficiency. The advanced core structure helps minimize no-load losses and operating noise.
The winding system uses high-conductivity copper or aluminum conductors with high-quality insulation materials. The optimized winding design provides excellent mechanical strength, thermal performance, and short-circuit resistance.
