Dry-Type Transformer

Servomax Limited is an exceptional provider of power-conditioning and power-saving equipment. Serving various locations across Pan India and a few other foreign countries, it is the best manufacturer and supplier of dry-type transformers. Extensively pledged with trust and excellence, our dry transformers are designed with spectacular features which are flexible for splendid customization.

Dry transformers are distinctive ones among the different types of transformers. Characteristic iron core and vacuum pressure resin-integrated high and low voltage windings are the ultimate elements of the dry transformers and avail in the best functioning. These units do not need any cooling means like oil and other liquids for cooling the transformers. The insulation system, therefore, has no necessity with the provisions for toxin vents. Class H or Class E type insulation is associated with them.

Our dry-type transformers are, hence, prominently ensured for safety – these avoid risks and dangers associated with fire and other power-variations. These can withstand high-levels of heat up to 180°C – 220°C.

Our manufacturing units include the best-quality raw materials and testing methods to offer high-grade and efficient dry transformers. We produce effective deliveries that follow national standards like BIS, IS 11171, and IEC 76. We engage in utilizing eco-friendly measures to follow green energy considerations.

The dry transformers we provide are used for measuring winding resistance, Voltage/Turns ratio, Impedance Voltage/Short Circuit, impedance and load loss, di-electric tests, no-load loss and no-load current. Our units are designed with a capacity range up to 2000 KVA –with the primary voltage up to 11 KV class and secondary voltage between 433 to 6600 V.
