Manchine Name |
Scope |
Coil Looping Machine |
Suitable for Pin to pin distance coil spreading up to 5 mtrs. |
Coil Spreading Machine |
Suitable for Span up to 2.0 mtrs & Pin to pin Length : 5.0 Mtrs |
Hydraulic Hot Molded Press for Resin Rich Coils |
Automatic presses are installed for molding and curing of insulation upto 5 mtrs of coils having Span length and slot size 50mm x 125mm |
Roebelling Machine |
For transposition of sub-conductor in large half coils for Hydro turbo generator |
Taping Machine |
Since the life and quality of insulation depends on proper tension, overlap, application & procedure throughout the portion to be taped and should be void free, taping machine ensurees all above requirements. The machine is suitable for both Resin Rich & Resin Poor insulation schemes. |
Surface Treatment for Corona Protection
Based on the voltage rating of the machine, surface treatment of the coils is done either by application of tape / plant or combination of Semi-conducting and stress grading paint / tape.
Testing of Coils
Coils are manufactured & test as per IEC-34, BS-4699, IS-325. BDS 0530, JEC 37, and Standard. We have facility to conduct the following tests :-
- Dimensions and shape control
- Inner turn test
- AC Hi-Pot Test
- TAN DELTA Test
- Impulse Test
- Resistance Test
- Inductance Test
Packing Coils
 all coils are individually wrapped in styrene, packed for Export worthy wooden packing, lined with thermo-coil
