Charged EVs | Hirect launches new copper conductor lines for traction motors and power transformers
Hirect has announced commercial availability of three copper conductor product lines: Continuously Transposed Conductors (CTC), Paper Insulated Copper Conductors (PICC) and Enameled Paper Insulated Copper Conductors (EPICC). The products are manufactured at Hirect’s newly commissioned copper processing plant and are targeted at power transformers, traction motors and high-power wound components for grid, railway rolling stock and catenary power supply systems.
The CTC line handles 5 to 63 strands per conductor, with strand dimensions from 2.5–12.0 mm wide and 1.0–5.0 mm thick, and transposition pitches adjustable from 25–200 mm. The PICC and EPICC lines cover copper widths up to 20 mm and thicknesses up to 8 mm. Insulation options span four enamel types and paper wrapping to 32 layers for CTC and 8 layers for PICC, with overall insulation thickness controlled between 0.25 mm and 5 mm. The CTC production area is dust-free and air-conditioned.
In-line quality control runs across 100% of output on all enameling lines. “We have integrated 100% in-line optical testing across all enameling lines, utilizing online pinhole and blister detectors alongside precision measuring equipment capable of maintaining tolerances of ±5 microns in drawing and rolling processes,” said Shailesh Jadav, VP Operations.
The facility is ISO 9001:2015 certified, with in-house testing covering Tan Delta, high-voltage breakdown, interstrand shorts and proof stress. The supply chain is compliant with EU Conflict Minerals Regulations and the Responsible Minerals Initiative.
Hirect is exhibiting at CWIEME 2026, May 19–21, Hall 27, Booth E72.
