OFHC is produced by the convesion of LME Grade A (Purity 99.99%) refined Copper cathodes by the process of melting & casting under strictly controlled conditions producing product with oxygen contents of less than 10 ppm (ASTM Standard). By managing the process parameters, it is possible to keep the oxygen content to less than 5 ppm for usage in specific applications like Vacuum Interrupters

By managing the process parameters, it is possible to keep the oxygen content to less than 5 ppm for usage in specific applications like Vacuum Interrupters. OFHC rods have higher electrical and thermal conductivity, higher recrystallization temperature and higher workability than standard grades of copper. Due to the lack of surface oxides, there is no dust generation during processing OFHC rod and such rod is ideal for use in applications such as CTC and enameled conductors where a dust-free conductor surface is critical. The application of OFHC is widely spread over electrical & electronic equipment which requires highly efficient, accurate and durable material.

Continuously transposed conductors (ctc) consists of a number of enameled rectangular wires (5-95 strands) made into an assembly.
Each strand is transposed in turn to each position in the cable and is then covered with layers of insulation paper. Transposition effectively eliminates inductance issues in the cable. Continuously transposed conductors are used in winding for medium to ultra high power transformers.
Ctc is manufactured by ofhc copper, and on specific customer request can also be made from etp copper.
