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 and application Reasonable protection against mechanical damage, appropriate to the choice of cable and the installation conditions, should be provided. Cables specified in this British Standard contain PVC, and when exposed to the effects of external fire will produce harmful smo… 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″. |
| 38 | 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 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, the correct size of duct should be used. Reference should be made to ERA Publication 69-30, Part III. 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. 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 drums or their becoming a hazard to the general public. A detailed guide to the safe handling of cable drums is available from the cable manufacturer.
