PRODUCT PORTFOLIO
RexEdge’s Power Offerings
Distribution Transformers
A distribution transformer is an electrical transformer used to step down medium or high voltage electricity to a lower voltage suitable for use by homes, commercial buildings, and industrial facilities.
Power transformer
A power transformer is a high-capacity electrical transformer used to transfer electrical power between different voltage levels, primarily in power generation, transmission, and high-voltage substations.
Its main purpose is to step up or step down voltage while maintaining the required power transfer with high efficiency.
Dry-Type Transformers
A Dry-Type Transformer is a transformer that uses air or solid insulation instead of insulating oil for cooling and electrical insulation. Unlike oil-filled transformers, dry-type transformers do not contain flammable liquid, making them ideal for indoor installations and environments where fire safety is a priority.

FREQENTLY ASKED QUESTIONS
Key inputs are the required capacity (kVA or MVA), primary and secondary voltage levels, vector group, impedance, tapping arrangement, cooling method and site conditions. Sharing your expected future load also helps size the transformer for growth.
Dyn11 means a delta-connected high-voltage winding and a star-connected low-voltage winding with an accessible neutral, with a 30° phase shift. It is widely used in distribution because the delta winding helps contain triplen harmonics and the star winding provides a neutral for single-phase loads.
An on-load tap changer (OLTC) adjusts the transformer's voltage ratio while it is energised and carrying load. An off-circuit tap changer (OCTC) can only be adjusted when the transformer is de-energised. OLTC suits applications where supply voltage varies frequently.
Yes. Every RexEdge transformer undergoes factory testing and quality verification before dispatch.
Yes. Electrical and mechanical specifications, including capacity, voltage, vector group, impedance, tapping and cooling, can be engineered around your project requirements.
