KAY PEE 's liquid-filled transformers are manufactured in accordance with the most demanding industry and international standards. Transformers can be used for indoor or outdoor applications and can be provided with off-load and on-load tap changers.

The transformer are manufactured in accordance with IS 2026/1977, IS 1180/2016, IEC 60076 or as per customer’s custom requirement.

The transformers will be suitable for outdoor installation with three phase, 50Hz, 11 kV system in which the neutral is effectively earthed and theyshould be suitable for service with fluctuations in supply voltage up to plus 12.5% to minus 12.5%.


Range : The standard ratings shall be 250, 315, 400, 500, 630, 800, 1000, 1250, 1500, 1600, 2000 and 2500 KVA for 11 kV distribution transformers.

Vector Group : As per customer’s custom requirement.

Core : The core shall be stack / wound type of high grade cold rolled grain oriented annealed steel lamination having low loss and good grain properties, coated with hot oil proof insulation, bolted together and to the frames firmly to prevent vibration or noise.

Core Test : The preliminary core loss test will be conducted before passing to the assembly stage.

Winding : HV and LV windings shall be wound from Super Enamel covered /Double Paper covered, aluminum /copper conductor/ foil.

Tapings : For ratings higher than 250 kVA, tapping shall be provided if required by the purchaser on the higher voltage winding for variation of HV voltage within range of (+) 5.0 % to (-)15.0 % in steps of 2.5%.

OIL : The insulating oil shall comply with the requirements of IS 335 or BS 148 Oil shall be filtered and tested for break down voltage (BDV) and moisture content before filling. The oil shall be filled under vacuum.

Tank :The transformer tank is of robust construction rectangular in shape and shall be built up of electrically tested welded mild steel plates of thickness of 6 mm for top and bottom and 4 mm side plate.

Conservator : The capacity of a conservator tank is designed keeping in Observation the total quantity of oil and its contraction and expansion due to temperature variations The total volume of conservator shall be such as to contain10% quantity of the oil. Normally 3% quantity the oil shall be contained in the conservator.

BUSHINGS: for 11 kV, 17.5 kV class bushings and for 0.433 kV, 1.1 kV class bushings shall be used.

TESTING : We are conduct all routin test.
