The British Approvals Service for Cables (Basec) has issued a public warning about Kaydour branded armoured cables. The product is multi-core PVC sheathed XLPE insulated steel wire armoured cable, in various sizes, which is claimed to comply with BS 5467. Basec's independent testing has indicated a number of serious faults including excessive conductor resistance and excessive armour resistance.
Conductors are up to two standard sizes smaller than that marked on the cables, which could result in overloading and overheating in use. It is said the armour resistance may also result in ineffective earthing. The cables can be identified by the brand name Kaydour printed on the cable sheath – these cables are not Basec approved or marked Basec.
This type of cable is commonly used for low voltage power distribution around sites or within buildings.
Jeremy Hodge, chief executive for Basec explained: "It is understood the cables originate from India and have been distributed in the UK through at least one supplier. It is not known if all cable with the Kaydour marking is suspect however any contractors or installers who are aware these cables have been installed in premises should test installations immediately for capacity, performance and safety. If safety concerns are raised, it is recommended the affected cables are removed and replaced by approved cables.
"End users are encouraged to check purchase documentation, design specifications and test their installation to ensure that the applied loading and earthing are acceptable. Findings should then be recorded in documentation."
