SINGLE PHASE TRANSFORMER

Compact & Efficient Voltage Transformation by Integrated Power & Engineering

Integrated Power & Engineering designs and supplies Single-Phase Transformers engineered for compact installation, high efficiency, and dependable voltage transformation. These transformers are widely used in residential, commercial, rural electrification, telecom, and light industrial networks—especially where space constraints, low load demand, or single-phase supply requirements exist.

Built with quality core materials, reliable insulation systems, and robust construction, our single-phase transformers ensure safe, stable, and long-term operation under varying load and environmental conditions.

Product Overview: Reliable Single-Phase Power Distribution

A single-phase transformer is used to step down medium or low voltage to utilization voltage for end-use equipment and localized distribution. Compared to three-phase units, single-phase transformers offer simpler installation, lower cost, and compact size, making them ideal for small loads and decentralized power networks.

Integrated Power & Engineering single-phase transformers are designed to:

  • Maintain stable output voltage
  • Minimize core and copper losses
  • Operate reliably in indoor and outdoor environments
  • Support long service life with minimal maintenance

Where are single-phase transformers commonly used? +
They are commonly used in residential supply, rural electrification, street lighting, telecom sites, and small commercial or industrial loads.
How do I select the correct kVA rating? +
The kVA rating is selected based on connected load, expected future growth, and allowable transformer loading under site conditions.
What is the difference between dry-type and oil-immersed single-phase transformers? +
Dry-type transformers are air-cooled and suitable for indoor or low-risk environments, while oil-immersed transformers offer better cooling and are preferred for outdoor or higher-duty applications.
Can the voltage ratio be customized? +
Yes. Primary and secondary voltages can be customized based on utility requirements and application needs.
Are pole-mounted versions available? +
Yes. We supply pole-mounted single-phase transformers designed for overhead distribution networks.
What protection features are typically provided? +
Standard designs support fuses, surge arresters, and grounding provisions as required by utility or project specifications.
What is the expected service life of a single-phase transformer? +
With proper loading and maintenance, a service life of 20–25 years or more can be expected.
Do you provide testing and after-sales support in Bangladesh? +
Yes. We provide routine testing, documentation, installation guidance, and after-sales technical support locally.
