Copper Telecommunication Cables
Depending upon the application optional sheathing designs can provide electrical shielding necessary for proper grounding and mechanical protection against rodent and other physical damage. For more mechanical robust applications such as in mining and in railway communications networks steel wire armouring (SWA) and or steel tape is available. A black UV stabilised and weather resistant polyethylene sheath is used on all constructions for the protection against long term outdoor exposure.
