GTB Transformers, India’s Leading Dry Type Transformer Manufacturer in Ludhiana has established itself as one of the most reputed transformer manufacturers in the marketplace.

An intrinsic byproduct of the transformation process is heat, specifically, the “I2R” (I=Current, R=Resistance) heating that occurs when current runs through a conductive wire. Heat breaks down transformer composition materials and insulation, resulting in less efficiency and shorter service life. Transformer heat is best controlled by the oil-filled transformers, which conduct the heat away from the heat-producing parts while protecting other internal transformer workings.
But with proper sizing and placement, as well as fans when appropriate, dry-type transformers which cool by air ventilation, provide excellent, low-heat service in tight enclosures and indoor situations where oil leakage could cause a fire or significant environmental hazard. Clearly, a system without these threats offers enhanced safety for indoor applications. A dry-type transformer will typically incorporate a design with greater internal clearances to allow for better heat dissipation. No fireproofing, oil catch basins or venting of toxic gasses are required and the transformer can be close to the load, minimizing secondary line losses. But a dry-type transformer also reduces maintenance with no need to replace transformer oil while avoiding the contaminant and composition checks necessary for proper oil insulation and cooling.

Our manufacturing units include the best quality raw materials and testing methods to offer high-grade and efficient dry transformers. We as India’s leading Dry Type Transformer Manufacturer in Ludhiana produce effective deliveries that follow national standards.

Dry type transformers are widely used in indoor situations where oil leakage could cause a fire or significant environment hazard. For example in places such as schools, institutions, mails hotels, malls and commercial buildings where reliability and safety are mandatory. Relative ease in maintenance of the transformers explains why GTB dry type transformer is often the choice of the customer.
