Product Profile of Cross Linked Polyethylene

KEI industries limited is one of the cable manufacturing companies in India. KEI industries limited manufactures high and low tension cables [EHT, HT and LT], control and instrumentation cables, house wires and stainless steel wires. KEI also manufactures specialty cables including braided cables, fire survival and Zero halogen cables. Kei Industries Limited offers LT Power Cables with PVC or XLPE insulation of voltage grade upto 3.3 KV. Xlpe means cross-linked polyethylene or vulcanized polyethylene. The basic material is low density polyethylene. Polyethylene is a thermoplastic material consisting of long chain of hydrocarbon molecules. At elevated temperatures these molecules tend to move relative to one another so that the material becomes increasingly deformable and eventually melt at the temperature around 110 degrees Celsius. The salient features of the Cross Linked Polyethylene or Xlpe Cables:

• Higher current carrying capacity

• Can be installed along cable routes without elevation limitations

• Dielectric losses are very small.

• Higher short circuit rating 250 degree Celsius as against 160 degree Celsius C for PVC

• KEI XLPE can retain flexibility down upto minus 40 degree Celsius

• Jointing and Termination is easy.

• They are not prone to fatigue damages due to vibrations or loading cycles.

• Has better resistance to most chemicals, oils, acids
