Special Features: Xlpe Insulation
Cross-linked Polyethylene Insulated Electric or XLPE Power Cables possesses excellent electrical, mechanical and heat-resistant properties. It has an advantage over PVC insulated cables because of its easy maintenance. Due to the invention of advanced XLPE insulation, EHV cables are also available today. Paramount XLPE cables are manufactured and tested in accordance with IS: 7098 (Part II) and other international standards.
Sustained Current Rating of HT XLPE Cables
The current ratings of HT XLPE cables given in the different tables are based on the following assumptions:
i) Maximum conductor temperature for conditions operation | 90◦C
ii) Ambient air temperature | 40 ◦C
iii) Ground temperature | 30 ◦C
iv) Thermal resistivity of soil | 150◦ cm/Watt
v) Depth of laying (to the highest point of the cables laid direct in the ground) | 90 cm
Method of Installation
Multi core cables are installed singly.
Single core cables are laid in trefoil formation.
