HOFR Cables have High current carrying capacity (App.40 higher). The coils inside the cables got high conductor working temperature to withstand. It also has more durable (life is more then double). It is heat resisting oil resisting & flame retardant and Low current derating factor at high ambient temperature. It gives better insulation properties and also Tough.
Economical ( 10% to 30%) for equivalent current carrying capacity.
Economical ( 40% to 60%) for long run ( as life is double)
Inventory is less.

Associate Flexiweld Pvt LTD has developed golden hofr cable ‘which’ works from-20c to 110c by increasing the working temperature of welding cable from 90c to 100c. The current carrying capacity has also increased and hence are most suitable for gouzing purpose etc. Derating factor for variation in ambient temperature are not given as the above current are based on ambient temp. Of 45c which is normally the maximum temperature at any place in india. These cables can also be used for high current, dc cable required by electricity board for tripping or as dc cable for electroplating.
