In the course of about two decades, R K Windings has had several eventful moments and many momentous milestones. Here are a few of them we cherish and draw inspiration from.
► 30.2 MVA Ultra Tech Cements (both rotor and stator), Maharashtra
This is a large size 4 pole 11 KV cylindrical rotor generator, originally manufactured by SIEMENS, GERMANY with VPI technology. The system has been re-designed by our design experts for resin rich system and successfully manufactured by RKEWW using special skills for rotor repair work including removing and re-inserting retaining rings. The damaged stator core is taken out, repaired, and re- staggered just in a span of 46 days. This has been done by RKEWW entirely to the satisfaction of inspecting authorities and consultants.
► 15MW Rayalaseema Alkaloid & Chemicals Pvt. Ltd, Andhra Pradesh
An imported BTH made 11 KV 2 pole turbo generator failed during operation. At RKEWW, half coils were manufactured and rewinding was done successfully just in a span of 35 days.
► 11.8MW Neelachal Ispat Nigam Ltd, Orissa
This machine was manufactured in foreign country with special
technology and failed in operation at Neelachal Ispat Nigam
Ltd, Orissa. The machine was sent to RKEWW to rectify the
fault and restore the quality of rewinding and manufacture
of special short circuit rings to the rotor. These rings were
developed indigenously and mounted to the rotor's damper bars
with highly skilled brazing technique.
► 2500 HP DC Motor Jindal Steel and power Ltd, Orissa
This motor is meant for plate mill drive system. RKEWW manufactured 720 new coils with class H insulation system and rewinded the armature just in a span of 42 days.
► 7MW-9MW Base power Ltd, Bhagyanagar, Karnataka
A Russian made turbo generator, failed in operation due to system surge problems. The Customer and its consultants requested RKEWW and assigned the responsibility of rewinding with new design for increasing the capacity of generator. RKEWW has done an excellent job and the generator has been working satisfactorily. “ELECTRICAL INDIA”, a leading electrical magazine appreciated this work and published an article in its magazine.
► RKEWW has not only proved its skills in rewinding of rotating electrical machines but also in rewinding of Static machines which reveals the best example of rewinding a 20 MVA, 132/11 KV Bharat Bijlee made Power Transformer belongs to M/s. HPCL.
►: RKEWW also manufactures new machines on case to case
basis with existing design as per the satisfaction of customer's
