Allied Wiring Cables

satisfy the requirements of the most exacting installation and the needs of contractors for reliable easy to install and readily available supplies of wiring cables for all types of buildings.

Allied Wiring Cables

are suitable for industrial, domestic, public and commercial buildings, farms and garages. They withstand effects of dampness, building materials, corrosive atmosphere and mechanical damage.

Allied Wiring Cables

are pliable enough to adapt to any configuration of wall surface yet are rigid enough to permit threading through holes or along runs. They are easy to strip and to terminate in wiring fittings or accessories.

Allied Wiring Cables

Provide all round performance, reliability and ease of handling. They are readily available from local branches and depots and users can rely on the technical backing and service of the AC organization.

Insulation materials
Polyvinyl chloride (PVC)

Allied Cables PVC compounds which comply with BS 6746. PVC is brightly colored for identification, is easy to strip and does not support combustion. It has good resistance to chemical attack generally and resists attack by most building materials, but it should not be allowed to remain in permanent contact with oils, greases, fats or creosote, nor with the fumes of substances or solutions used as wood preservation It does not support mold growth and is suitable for used in tropical climates, but cables insulated other than Black PVC, should not be permanently exposed to direct tropical sunlight. PVC gradually hardens as the temperature decreases but recovers its flexibility on returning to normal temperature.

Operating temperatures

Maximum service operating temperatures of 70 C for PVC insulated wiring cables and conduit wires indicate that a normal service life can be expected when the combined ambient temperature and the conductor temperature due to the current does not exceed these figures. PVC compound will withstand occasional overloads of short duration due to fault currents without deterioration. If PVC wiring cables are being installed at temperatures below 0 C, care must be taken not to bend them sharply. It is preferable to keep the cable in a warm place for 24 hours before installation under these condition.

Current ratings

In normal practice, the recommended current rating as given in the IEE Regulations for the Electrical Equipment of Buildings, should be followed. In cases of doubt or in exceptional circumstances, advice should be sought from the Allied technical advisory service.

Cable diameters

The diameters of the PVC cables given in this publication correspond to the nominal diameters given in BS 6004 subject to tolerances allowed.
