PVC Insulated Split Concentric Cables
PVC Insulated Split Concentric Cables
anufactured to BS 4553-1 Table 3.
The insulated neutrals and bare earth wires are laid in a concentric layer around the insulated phase conductor with PVC string separators separating the neutral and earths. This is then bound with a clear polyester tape and then PVC sheathed.
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.
