wearing power cable designed for the supply of mains electricity and is found in underground system, power networks and cable ducting and (STA&SWA) CABLES. Consists of: 1-Conductor : as a good conduction material 2- Insulation : P.V.C or XLPE because it have a good water resistance and excellent Electrical properties 3-Bedding : to provide a protective boundary between inner and outer layers of the cables 4-Armour : STA , SWA provide a mechanical protection which means the cable can with stand higher stresses 5-Sheath : P.V.C sheath to provide additional protective from external stresses
Standards: IEC 60228 IEC 60502
Applications: Transmitting electrical power or data in harsh environment They are used primary in industrial applications and in raceways Used to found in underground system, power networks It is used in systems that need to extend cables with different burial systems.
