Extreme heat resistant cable handles tough conditions

29 June 2005 Interconnection

Axon produces the Vibraflame range of cable, which is designed to resist higher temperatures and more rigorous operating conditions than most other types of flexible cable. Local distributor, Hiconnex, says that they are ideal for the most demanding applications in steel and aluminium plants, coke mills, glass factories, oil refineries and offshore rigs and in various military and space installations and equipment.

Vibraflame cables can work where other cables fail because they will maintain electrical circuit integrity at peak temperatures as high as 1565°C. In fires exceeding 1050°C, they will maintain integrity for a minimum of 4 hours. In molten steel or aluminium, they can function for 15 minutes (minimum), allowing time to take steps to prevent costly equipment damage. In addition to heat, Vibraflame is resistant to weather, water, chemicals, acids and lubricants.

Hitesh Pema, managing director of Hiconnex, says: "In actual field use, they have proven to last at least five times longer than any other heat-resistant cable. Plants generally experience savings of 60% or more during the first year after switching to Vibraflame cable. In addition, Vibraflame often makes new, simpler and money-saving layouts possible - they may for instance, eliminate the need for protective conduits."

He says that Vibraflame cables meet the most rigid international and national tests such as NBN C 30-004 with test conditions of: temperature produced by gas burner of 900°C at approximately 50°C for a duration of 3 hours; mechanical impact every 30 seconds; current leakage not to exceed 1 A per conductor; test must be passed by four successive samples.
