  3. Introduction Introduction Power Cables -An assembly of two or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power.

  4. Construction Construction

  5.  Conductor – Stranded / Solid / Circular shaped- Aluminum / Copper  Insulation – PVC /XLPE/HR PVC / Zero Halogen  Inner Sheath – PVC/HR PVC /FR/FRLS PVC  Armouring – G. S.Round Wire/ Flat Strip or Aluminum Wire /Flat Strip  Outer Sheath – PVC /HR PVC/FR/FRLS PVC /Zero Halogen

  6. Types & sizes Types & sizes  Types 1.1 kV PVC /XLPE as per IS : 1554 – (Part-I) / IS : 7098(Part- I)/BS /IEC.  Sizes Single Core 1.5 to 1000 sq. mm Multi core 1.5 to 630 sq. mm

  7. Features Features  These cables can carry high current with high short circuit rating 250°C as against 160°C for PVC.  Dielectric losses are very less in these cables.  LT power cable is flexible, lightweight, fire-resistant in nature.

  8. Application Application  LT power cable may be installed as permanent wiring within buildings, run overhead, buried in the ground or exposed.  And Flexible power cables are used in mobile tools, portable devices, and machinery.
