A range of copper conductors for transformers, rail systems, and industrial power networks aims to improve efficiency, insulation performance, and manufacturing precision.
Hirect has commercially launched a new portfolio of high-performance copper conductors designed for transformers, traction motors, and other high-power wound components. Manufactured at the company’s newly commissioned copper processing facility, the range includes Continuously Transposed Conductors (CTC), Paper Insulated Copper Conductors (PICC), and Enameled Paper Insulated Copper Conductors (EPICC).
The launch strengthens Hirect’s position in the global transformer supply chain and supports the company’s expansion across international markets. The conductors are targeted at critical infrastructure applications, including power transmission grids, railway rolling stock and catenary systems, and industrial power distribution networks.
The new manufacturing setup enables Hirect to produce conductors across a wide range of dimensions and insulation specifications. Its CTC lines are designed for high-efficiency transformer applications and can manufacture conductors with 5 to 63 strands. Strand widths range from 2.5 mm to 12.0 mm, while thicknesses range from 1.0 mm to 5.0 mm. The system also supports adjustable transposition pitches between 25 mm and 200 mm.
For PICC and EPICC products, the production lines can process copper widths up to 20 mm and thicknesses up to 8 mm, enabling use across a broad range of electrical applications.
Hirect’s insulation systems are designed to meet varying thermal and electrical performance requirements. The enameling lines support four different insulation coatings, while the paper insulation systems can wrap up to 32 layers in a single pass for CTC conductors and up to 8 layers for PICC conductors. Insulation thicknesses can be maintained within a controlled range of 0.25 mm to 5 mm.
To ensure manufacturing consistency and product quality, the company operates the entire CTC production area within a fully air-conditioned, dust-controlled environment.
“Exceptional quality and responsible sourcing are the cornerstones of our newly expanded copper operations. To guarantee flawless insulation and dimensional accuracy, 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. Our entire supply chain is compliant with EU Conflict Minerals Regulations and the Responsible Minerals Initiative.” — Shailesh Jadav, VP Operations, Hirect.
