KEI Industries Ltd

Okhla, Delhi

KEI Industries Limited is one of the leadinglow tension/ voltage cable manufacturers in Indiawith PVC or XLPE insulation of voltage grade up to 3.3KV that conforms to various Indian and International Standard Specifications. KEI also manufactures other types of cables likeLT power cablesandlow voltage cablesamong others that you will find in our listed catalogue.

XLPE means cross-linked polyethylene or vulcanized polyethylene. The base material is low density polyethylene. Polyethylene is a thermoplastic material consisting of a 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 will eventually melt at the temperature around 110C.

By means of a process similar to the vulcanization of rubber, the polyethylene molecules can be cross-linked. The process of cross-linking or vulcanization for our low tension cables, LT power cables and low voltage cable products consists of producing chemical bonds at intervals between the long molecular chains to give them a ladder effect which prevents slippage between molecules. As a result of cross-linking, the material becomes heat resistant and does not become soft at higher temperatures. Further, it has better resistance to stress cracking and good resistance to ageing in hot air. With the change of structure there is no adverse effect on electrical properties.

The Advantages of KEI XLPE Low Tension Cables

• Dielectric losses are minimal
• Higher current carrying capacity
• Higher short circuit rating 250C as opposed to 160C for PVC
• KEI XLPElow tension cablescan retain flexibility down upto -40C
• Jointing and Termination is easy
• The LT power cables are Lightweight.
• They are not prone to fatigue damage due to vibrations or loading cycles
• Have better resistance to most chemicals, oils, acids, etc.
• Can be installed along cable routes without elevation limitations

KEI also manufactures low voltage4 core power cablesand3 core cablesand4 core cablesupto 33 kV.

EI has been at the forefront of Indias wire and cable industry for the last forty years.Solar photovoltaics is now, after hydro and wind power, the third most important renewable energy source in items of globally installed capacity. This results in the great demand for SOLAR CABLE. Solar cable is the interconnection cable used in photovoltaic power generation. A solar cable interconnects solar panels and other electrical components in the photovoltaic system. Matching step with the environment friendly shift the Solar Cable has been made which performs highest standards of application in its diverse usage.
