Electrical transformers, or simply transformers are the electrical devices meant for transforming the electric energy. The basic function of a transformer is to alter the voltage, usually from high to low. In other words, a transformer solves the purpose of transiting the power from the power plants to houses, offices, markets, malls, etc., in an appropriate state. Nowadays, electrical transformers are available in several different types. Also, the size of electrical transformers vary according to the area of their application. For instance, the transformers required for power stations are multi-ton units, which are large and bulky; electrical transformers used on electric poles are intermediate units, which are medium sized; electrical appliances in homes, offices, etc., require compact transformers.
Electrical transformers manufactured by Power Engineers & Consultants are precisely and efficiently engineered to render optimum value for your money. Our transformers ensure safe and economical transfer of current from the main power supply to the relevant equipment. Our range of electrical transformers is mentioned below:
Special Purpose Transformers
The special purpose transformers found their application in areas where the voltage requirement of the machines available differ significantly from the standard voltage. Our special purpose transformers are at the forefront in the industry. We strictly adhere to the international quality standards while manufacturing these transformers. We also entertain custom requirements up to 5000 kva.
Power Distribution Transformers
The main function of a power distribution transformer is to transform the electrical supply from the main source into a predefined voltage, which should be appropriate for the destination equipment. We use high quality materials and advanced production techniques for manufacturing these transformers. We are also capable of custom designing these transformers according to the client's specifications. Our power distribution transformers are primarily demanded by large manufacturing units, electricity boards, and windmills.
Ultra Isolation Transformers
Ultra isolation transformers are considered ideal for eliminating line disturbances and preventing faulty and erratic operation of certain sensitive equipment like computer, computerized machines, medical equipment, CNC machines, digital communication telemetry systems, and so. We are quite specialized in manufacturing this particular variety of transformer. Our ultra isolation transformers are highly effective in eradicating the disturbances generated in consequence of the noisy equipment load which get injected into the power line. These transformers are also custom engineered by us to suit the specific needs of our clients.
