Power Cables


Shital Electric Co are Authorised Distributor for Polycab Power Cables & Politech Shielded Cables  A power cable is an assembly of two or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power. Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed. Medium and high-voltage power cables, in circuits over 2000 volts, will have a shield layer of copper or aluminum tape or conducting polymer. If an unshielded insulated cable is in contact with earth or a grounded object, the electrostatic field around the conductor will be concentrated, resulting in corona discharge, and eventual destruction of the insulation. As well, leakage current and capacitive current through the insulation presents a danger of electrical shock on contact. The grounded shield equalizes electrical stress around the conductor, diverts any leakage current to ground, and blocks capacitive current from flowing into objects (or persons) touching the exterior of the cable. The Power Cables are used under ground as well as overhead transmission of power in power plants, industries, projects and all other electrical installations.

Selection of Power Cables


Power cables are generally selected considering the application. However following factors are important for selection of suitable cable construction required to transport electrical energy from one end to the other.

  •     Possible overloading duration &  magnitude.

  •     Route length and voltage drop.

  •     Flame retardant properties.

  •     Plant safety requirements.

  •     Mode of installation considering installation environment such as ambient & ground temperature, chemical and physical properties of soil.

 Parameters required are as under

  •     Voltage Grade - 650/1100 Volts.

  •     Relevant Indian standard - IS-7098 (Part-1) - 1988 or Intarnational standard - IEC- 60502 & BS-5467/DIN.

  •     Number of cores. - Single, Two, Three, Three & Half or Four Cores.

  •     Conductor - Size, wherever applicable size of reduced natural conductor.

  •     Conductor material - Copper / Aluminium

  •     Type of Insulation - XLPE
