Transmission and Distribution Electrical Engineering, Third Edition

The selection of cables for particular applications is best done with reference to the latest and specific manufacturer s cable data and application guides. It is not therefore appropriate to include here comprehensive tables giving cable dimensional, weight and current rating information. This chapter concentrates on the properties of different types of LV, MV and HV power cables, their merits for different applications, cable sizing and loss calculations, useful installation practices and cable management systems. A section is also included on control and communication, including fibre optic, cables. Technical specification details are included such that competitive quotations from leading manufacturers may be obtained. Consideration is given to the safety implications associated with gases and smoke emitted from cables under fire conditions, especially where installed in public places.
Table 12.1 details some useful IEC and National cable Standards.
| IEC standard | Brief description and comment |
|---|---|
| 60055 | Paper-insulated metal sheathed cables for rated voltages up to 18/30 kV (with copper or aluminium conductors and excluding gas-pressure and oil-filled cables). Covers tests and general construction requirements. In the UK BS 6480 is used. |
| 60096 | Radio frequency cables various parts cover general requirements, measuring methods, specifications and tests. |
| 60141 | Tests on oil-filled and gas-pressure cables and their accessories. Includes oil-filled (normal and high pressure) cables up to 400 kV and gas-pressure cables to 275 kV. |
| 60183 | Guidance for the selection of HV cables, the conductors size, insulation... |
