CTC & Ventilated CTC

Continuously Transposed Conductors (CTC) consist of a number of enameled rectangular wires (5 - 64 strips) made into an assembly. Each strand is transposed in turn without a twist along with its length, and then covered with layers of insulation paper or film.

Chandra Proteco Ltd CTC is made of OFHC copper. We can supply polyester rope CTC and a specially pre-profiled CTC called VCTC. We can also supply hardened type of CTC (CPR1, CPR2, CPR3) as well Self-bonding CTC which improves mechanical and electrical strength and decreases short circuits.

Normal CTC 5 - 64 strips
Ventilated CTC 31 - 64 strips
Epoxy-bonded CTC 5 - 64 strips
Silver bearing CTC 5 - 64 strips
Hard type CTC

CPR1 5 - 64 strips
CPR2 5 - 64 strips
CPR3 5 - 64 strips

Advantages of CTC & VCTC
Due to the extra cooling provided by VCTC the size of the coils reduces thus reducing the overall tank size.
Shortened winding time for transformers
Decreased size and cost of transformers
Reduced electrical losses
Improved mechanical strength of winding by epoxy coating
Excellent winding ability and simple handling
