INQUIRY

Application:
Concentric cable are devised for use to provide the final connection to residential properties. Additional functionality includes use for sub-main distribution and within high-rise buildings and street lighting systems.

The choice between Concentric and Split Concentric cable is determined by the supply type: TN-C-S supply for Concentric and TN-S supply for Split Concentric. These are LSZH cables (low smoke zero halogen) with the outersheath suitable for installations requiring a reduction to the risk to human life or sensitive equipment in the event of fire.

Concentric cable are used for power supplies with Protective Multiple Earthing (PME) systems, where a combined Protective Earth (PE) and Neutral (N) – together known as the PEN – connects the combined neutral-and-earth to real earth at multiple locations to reduce the risk of electric shock in the event of a broken PEN.

Split concentric cables are used when the power supply has separate PE & N conductors and are only combined as PEN near the power source. The Protective Earth and Neutral are not connected after the building entry point

Constrction:

  • Complete Cable:
    Concentric Cable consists of two compact aluminum conductors individually insulated with RW90 XLPE insulation, laid in parallel, with a helical plain copper wire serving and an overall PVC jacket covering. Thecopper wire serving is the neutral. The product meets the USEB-90 cable requirements of CSA C22.2 No. 52.
  • Conductors:
    The aluminum stranded conductors are Class B compact 1350-H16 (3/4 hard) aluminum.
  • Insulation:
    The insulation is a black Cross-linked Polyethylene (XLPE) meeting the requirements of CSA C22.2 No. 38 for Type RW90 insulation.
  • Neutral Conductor:
    An annealed, plain copper wire serving is applied over top of the two power conductors. The neutral conductor may be equal to the equivalent copper AWG size of the power conductor, or it may be reduced.
  • Binder/Separator Tape:
    A separator tape is applied overtop the helically applied neutral conductor wires.
  • Jacket:
    Black PVC jacket is extruded over top of the cable assembly. The jacket is a weather- resistant, sunlight-resistant, 60°C/-40°C FT1- rated material.
  • Phase Identification:
    Both of the XLPE insulated power conductors are black. One conductor will have a white coloured print legend on the surface of the insulation. The print legend includes the required CSA markings and General Cable manufacturing plant code,year marking, and “1-ONE-1” printed phase identifier. The other conductor will only have the “2-TWO-2” marking. All cables provided with sequential print marking
