ACA says further cable recalls needed

Yet another batch of faulty electrical cables has been sold and installed over the last three years, according to the Australian Cablemakers Association (ACA). This follows on from the Infinity- and Olsent-branded cable recall, reportedly the largest of its type in Australia's history.

The ACA says that the voluntary trade recall issued for Ecables Copper Clad Aluminium RE 110 Insulated power cables should be extended, based on sustained testing.

According to information released by the ACA, it is believed that the products have been predominantly used for major projects such as apartment buildings, hotels and commercial installations.

ACA Chairman Andrew Davenport said the latest round of recalls applies to Ecables CCA product sold between 1 January 2012 and 30 June 2014.

“The cabling is designated to operate at temperatures up to 110°C and to conduct low-voltage power up to 1000 V, which means it is supposed to be able to withstand higher load currents than similar size but lower temperature-rated cables,” Davenport said. “The cable is marked as rated to a conductor temperature of 110°C, but comprehensive testing has shown that the insulation fails at temperatures well below this rating and that the cable actually melts if the temperature reaches 110°C.

“Similarly, if the cable is operated at its rated current-carrying capacity, then heat from the conductor causes severe and dangerous insulation deformation. This would leave the live conductors exposed and present a serious risk of fire, electrical injury or electrocution. ACA believes this insulation failure is even more dangerous and concerning than the recently recalled Infinity and Olsent cables.”

While the recall applies to all cable currently in the inventory of electrical contractors, as well as product that has been installed in situations where it is exposed to temperatures of 50°C or more, the ACA wants a complete recall, ensuring safety of buildings and occupants.

“It is impossible to anticpate the future operating conditions for installed cable, even if it is not currently exposed to higher temperatures,” Davenport said.
