Instruction of SplitConcentric Cables
Split concentric cables are largely used by Distribution Network Operators(DNO) for providing final service connection to customer properties. Otherapplications include sub main connections within high rise buildings and streetlight systems. The cables are designed for direct burial and the polymericcovering of the Neutral conductor ensures greater corrosion resistance
