Aerial Bunched Cable (ABC) is a very novel concept for overhead Power distribution. ABC provides higher safety and reliability compared to bare conductor overhead distribution system. The other advanctages are lower power losses and system economy by reducing installation, maintenance and operation cost. This system is ideal for rural distribution and specially suitable in difficult terrains like hilly areas, forest and coastal areas etc.ABC is also considered as a better choice for power distribution in densely populated areas where laying of underground cable is either difficult or extremely expensive. This...

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 : Higher current rating allows to select lower size of XLPE cable compared to PVC cableHigher short circuit rating 250°C compared to 160°C that for PVC...
