Features : Designed to facilitate land –based activities in the oil, gas , petroleum and chemical Industries where the spillage or seepage of corrosive liquids and vapors pose a threat to cables .
Type Tested and certified by : Kema and esma
Manufactured to : Bs 6622, iec 60502-2& eemua 133
Range : single core copper /aluminum conductor with lead sheathing from 50mm to 1000 mm, three core cables with copper /aluminum conductor with lead sheathing from 50mm to 400mm
Benefit: The lead sheath provided in these cables performs the mechanical function of acting as a barrier o entry of hydrocarbons. The lead sheath of the cables can also be engaged to perform the electrical function of sharing the earth fault current with the armoured lead sheath also protecting cables against radical moisture ingress .
