XLPE Power Cables
LT CROSS-LINKED POLYTHYLENE (XLPE) POWER CABLES
LT 'HILLS' CROSS LINKED POLYTHYLENE (XLPE) INSULATED POWER CABLES Hills Cab has developed a special grade XLPE compound to be used as the insulating material suitable for LT (upto 1100 volts) applications. This is a thermoset type of polymer enriched with cross linking agent. This is extruded over the conductor using modern extruder and is throughly cross linked under controlled conditions. This XLPE insulation overcomes the drawbacks of PVC, hitherto extensively used as an insulating material, without losing any of PVC's desirable properties. Following are the advantages of XLPE Insulated Cables over that of PVC Insulated cables.
Higher Cureent Rating
Withstands continuous conductor temperature of 90°C, whereas PVC withstands only 70°C, which means higher current carrying capacity.
Higher Overload Capacity
XLPE cables handle 130°C in emergencies, allowing continued load if others fail—unlike PVC, limited to 120°C.
Higher Short Circuit Rating
Can withstand conductor temperatures of upto 250°C during short circuit - PVC cannot withstand more than 160°C.
Lighter, smaller bending radius
Lighter weight and smaller bending radius make XLPE cables ideal for tight spaces, needing less support and reducing installation costs.
Lower Di-electric Constant and Power Factor
Results in saving in power losses which means saving in costs, particularly for higher voltage.
Better Impact, Abrasion, Corrosion, Resistance
Safer than PVC Cables against mechanical damage, abrasion and corrosion.
Quality Assured
- At Hills Cab, Quality Assurance is ensured through planned, stage-wise quality checks. These quality checks are made starting from the raw material right through every stage of manufacturing.
- In particular, the property and specified test for XLPE compound is checked and the absence of contamination in the compound is noted against each batch of material received.
