• Optic Fibre Cables

Commercial Advantages:

• Lower laying cost because of comparatively smaller diameter of cable and higher weight*.
• Lower installation charges as the diameter of cable is comparatively lesser with smaller bending radius, requiring less space requirement for laying cables.
• **One size lower cable can be used as compared to PVC insulated cable.

Advantages of XLPE Cables –

• Higher Electrical Strenght Retention
• Higher Short Circuit Rating
• Better Electrical, Mechanical & Thermal Properties
• Easy Joining & Termination

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

1. Maximum operating voltage.
2. Fault level..
3. Load to be carried..
4. Possible overloading during & magnitude..
5. Route length and voltage drop..
6. Mode of installation considering installation environment such as ambient & ground temperature  as well as chemical & physical properties of soil..
7. Flame retardant properties..

All sizes of XLPE cables are designed for standard operating conditions in India and abroad. The standards adopted are after duly considering the geographical I climatical conditions and general applications of powerfor utilities, distribution and generation purposes. The cables are manufactured conforming to Indian & International cables specification for XLPE Insulated cables. Customer specific requirements can also be met.
