Distribution Transformers up to 2500 kVA
Amrest Electricals Limited manufactures distribution transformers in oil-immersed, single phase and dry-type designs, built as per customer specifications and voltage levels.
Types of distribution transformers
Oil-immersed
Immersed in high-grade insulating oil, which acts as the cooling and insulating medium. Widely used in outdoor installations and high-load applications.
- Oil-cooled and naturally air-cooled (ONAN)
- Fitted with conservator, breather and Buchholz relay
- Easy to maintain and monitor
- Designed for long service life and reliability
Single phase
Ideal for rural electrification, residential power supply and light commercial loads. Compact, efficient and cost-effective.
- Voltage ratings up to 33kV
- Capacity up to 100 kVA (customizable)
- Lightweight and space-saving design
- Pole-mounted or pad-mounted installation
- Oil-immersed and dry-type variants
- Low maintenance and long operational life
Dry-type cast resin
Windings are encapsulated in epoxy resin, giving excellent protection against dust, moisture and chemical pollutants.
- Fully encapsulated windings for maximum insulation
- High resistance to fire and moisture
- Safe for indoor installations
- Minimal maintenance required
- Long life expectancy
- Suitable for humid and polluted environments
Vacuum pressure impregnated (VPI)
A cost-effective dry-type solution for medium-duty indoor use.
- Low noise and vibration operation
- High thermal endurance
- Ideal for commercial buildings, hospitals, data centers and more
- Easily repairable and service-friendly
