Increasing urbanisation and population density to stay connected are constantly placing new demands on railway technology. The high availability and smooth operation of rail vehicles depends largely on the cables and wires used. They must comply with special safety regulations and fulfil functions in order to be approved for rail coaches, locomotives etc. E-beam technology, is an efficient means of cross-linking polymers used for wire and cable insulation, harnessing and jacketing and added state of art high speed tandem lines for thin-wall insulations has special design cross head which gives the high eccentricity on cable.
