ENATS 09-6

Description:

This standard covers multicore and multipair cables with PVC or Polythene insulation. The conductors are 1/0.8mm PCW, (Issue 6), 7/0.67mm PCW (Issues 5 or 6), or 1/0.9mm TCW (Issue 5)

PVC insulated multicore cables are intended for use in power stations and substations for remote operation of electrical switchgear.

Polythene insulated multipair cables are intended to provide circuits for feeder protection and for speech and data transmission.

PVC insulated multipair cables are intended for use with control, indication and alarm equipment for switchgear and similar systems.

Issue 6 substitutes 1/0.8mm conductor for 1/0.9mm conductor for rationalization purposes.
