Laser Cable produces LT Power Cable with PVC or XLPE Insulation of Voltage grade upto 3.3 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 :
