In view of increasing demand of E-beam Cables in India, Company has diversified into manufacturing of Electron Beam Crosslinked Cables by establishing a State of the art manufacturing facility situated at Rewa (M.P.). This E-Beam facility is a 3.0 MeV Electron Beam Accelerator along with suitably designed handling systems suitable for irradiation of various types of Electrical & Automotive Cables & Wires, PE Sheets, Polymeric Tubes/ Pipes, Heat Shrink products, Gems & Diamonds, Medical product sterilization. The E-Beam irradiation curing of Elastomer and other polymeric cables has several advantages over conventional steam/dry curing method.

E-BEAM TECHNOLOGY

By crosslinking, polymer chains are linked together by so-called cross links. A three-dimensional polymer network is created where the molecules have been joined together into a new non meltable polymer system. Now, the polymer chains loose some of their ability to move as individual chains. The result is no melting.

E-beam technology - Ionizing energy, as provided by an accelerated electron beam (EB), is an efficient means of crosslinking polymers used for wire and cable insulation and jacketing. In this process, the three-dimensional unmeltable network is produced. This can be done without heat. E-beam processing is fast, good, controllable and in a lot of cases more economical than thermal and/or chemical crosslinking.

The electron beam processing in wires and cables helps to improve thermal, chemical, barrier, impact wear and other mechanical properties to meet the demanding applications of the customers in wires and cables.

ADVANTAGE OF ELECTRON BEAM OVER CHEMICAL CROSS LINKING
  • Higher Degree of Crosslinking up to 75 - 80 % in E -beam cables compared a 50 - 55 % in chemically cross linked.
  • No polymer degradation due to exposure to high temperature as EB Crosslinking occurs at room temperature.
  • No oxidative degradation in Polymer due to left over chemicals, oxygen in air and operating temperature of cable, as observed in chemical crosslinking.
  • Curing time is less as compared to chemical curing.
  • 125°C Temperature rating for : Long life, Higher Ampacity , Protection from Thermal Overloads.
  • Improved abrasion resistance, which can result in reduced wall thicknesses to save raw materials, space, energy and weight. A lower weight gives an extra premium in terms of lower energy consumption in trains, ships, planes and other transportation systems.
  • No dripping in case of fire, less flame spreading, less smoke, less pollution in case of fire.
  • No immediate melting means no immediate short circuits in areas like elevators, large public buildings like schools, theaters, airports, stadiums, ferries and so on.
  • Reduced risk of damage by mechanical pressure and cutthrough, no short circuits and electrical sparking.
  • Improved oil and fluid resistance makes the cables function longer during immersion.
APPLICATION OF E-BEAM TECHNOLOGY

VTL has installed suitable handling systems to use the facility for following products


  • Locomotive Cables for Railways
  • Solar PV Cable
  • Ship Wiring Cables
  • Wind Mill Cables
