PVC rapidly replaced rubber for wiring cables and for Power cables insulation in Europe, shortly after 1945 and 1950 respectively .In India, the PVC power & Control Cables came into operation in early 1960s. The use of PVC provided cables of excellent quality which were clean and much easier to handle. Further, simplified terminators and jointing techniques make these cables eminently suitable among other applications for Industrial and Mining installation.

Advantages of PVC Cables :

• The insulation resistance and breakdown strength are practically unaffected by moisture. These cables are thus suitable for laying even under water.
• Cables can be overloaded for short periods without any appreciable effect on cable life.
• The cables can be laid vertically and on steep slopes as there is no impregnating compound involved.
• The cables are flame retardant since PVC ignites with great difficulty and is self extinguishing
• These cables are immune to chemicals normally encountered in practice.
• Due to their lightweight, PVC Cables are easy to install and handle. Small bending rapider permit the termination of these cables in limited space.
• Low tension PVC Cables do not normally require sealing ends, when terminated indoor. The terminations can therefore be effected quickly and economically.
• PVC Cables have tough but smooth outer covering and are thus abrasion proof.
• PVC cables are not affected by vibration.
• PVC Cables have high short circuit capacity since they can withstand a high transient temperature without any deformation of insulation or displacement of conductor.
• PVC Cables have a long service life.

Vishnu Cable produces LT Power and control Cable with XLPE Insulation of Voltage grade upto 1.1 Kv conforming to Indian and various International Standards.
Cross Linked Polyethylene (XLPE) :
XLPE means crosslinked Polyethylene. The compound is based on high molecular weight polymer. High degree of crosslinking is attained in the processed form and thus attains excellent electrical and mechanical properties.
Advantages of XLPE Cables :

• Higher current rating allows to select lower size of XLPE cable compared to PVC cable
• Higher short circuit rating 250C compared to 160C that for PVC cables
• Resistant to heat deformation while PVC is prone to heat deformation
• Respective short circuit/overload condition is reliable
• Lower dielectric loss
• Jointing & Termination is easy
• Lighter in weight considering lower overall diameter
