This British Standard specifies requirements for construction and gives methods of test for PVC-insulated single-phase split concentric cables for operation on an earthed neutral system at nominal voltages up to and including 1 000 V between phases and 600 V to earth.

The cables specified in this part of BS 4553 have a central phase conductor insulated with PVC and a concentric layer comprising bare copper wires (earth continuity conductor) and copper wires covered with extruded polymer (neutral conductor). The cables are intended for use in fixed installations in industrial areas, buildings and similar applications. They are suitable for use in situations where the combination of ambient temperature and temperature rise due to loading current results in a conductor temperature not exceeding 70 °C, and for a maximum short-circuit conductor temperature of 160 °C.

Guidance concerning selection, installation and usage is given in Annex A, Annex B, and Annex J respectively.

Construction requirements and methods of tests for cables intended for use in fixed installations in industrial areas, buildings and similar applications. For use where current loading gives conductor temperature rise not exceeding 70°C and where the maximum short circuit conductor temperature is 160°C.

17 Cable selection and design
The products specified in this British Standard are intended to be used for the supply of electrical energy up to the rated voltage indicated on the cable.
These cables are intended for use within a nominal power frequency range of 49 Hz to 61 Hz.
In addition to the current ratings, due regard should be given to:
The possible effects of transient over-voltages should be recognized as they can be detrimental to cables.
Environment/application
Reasonable protection, appropriate to the choice of cable and the installation conditions, should be provided against mechanical damage.
Cables specified in this British Standard contain PVC and when exposed to the effects of external fire will produce harmful smok…
Cables may be harmed by exposure to corrosive products or solvent substances, especially petroleum based chemicals or their vapours.
Special precautions are required when cables are to be installed in areas classified as hazardous, and reference should be made to BS EN 60079-14.
Cables specified in this British Standard are not specifically designed for use:
If cables in accordance with this specification are exposed to localized heat, solar radiation or high temperature ambient conditions, or there is a possibility of higher soil thermal resistivity, the current carrying capacity will be reduced.
The standard sheathing compounds supplied on these cables do not provide protection against damage by rodents, termites, etc.
Loaded cables may have surface temperatures which require protection against accidental contact.
Installation
Precautions should be taken to avoid mechanical damage to the cables before and during installation.
Exceeding the manufacturer’s recommended maximum pulling tensions may result in damage to the cable.
If cables are to be installed in ducts, reference should be made to the cable manufacturer for a duct size corresponding to the current rating quoted.
The type of jointing and filling compounds employed should be chemically compatible with the cable materials.
The cable support system should be such as to avoid damage or danger under normal or fault conditions.
18 Cables specified in this British Standard are designed for fixed installations only, e.g. they are not for use as trailing or reeling cables.
Repeated over-voltage testing can lead to premature failure of the cable.
The selection of cable glands, accessories and any associated tools should take account of all aspects of intended use.
Storage and handling of drums
Cable drums should be regularly inspected during storage to assess their physical condition.
Battens, where applied, should not be removed from drums until the cable is about to be installed.
When handling drums, reasonable precautions should be taken to avoid injury. Due regard should be paid to the weight, method and direction of rolling, lifting, protruding nails and splinters.
Care should be taken to avoid deterioration of the drums or their becoming a hazard to the general public.
The cable manufacturer should be consulted for detailed guidance as to the safe handling of cable drums.
