H SPLIT CONCENTRIC

H SPLIT CONCENTRIC 25.0

Split concentric cables are predominantly used by Distribution Network Operators (DNO’s) when providing the final service connection to domestic properties. Split concentric cables are also suitable for sub main distribution and have been found to be particularly useful within high rise buildings and street lighting systems. These cables are designed to be installed in air, or for burial in free draining soil conditions
