Advantage of electron beam crosslinking compare to chemical curing for wire and cable application

Apar Industries limited manufactured different varieties of cables like HT XLPE, LT XLPE, Optical fibre & Elastomeric cables. Elastomeric cables can be crosslinked by chemical curing as well as E-beam curing. Chemical curing is done by adding curing agent like peroxide & Sulphur with compound & crosslinked in presence of heat. Normal medium voltage & high voltage cables are manufactured by chemical curing. E-beam curing cables does not required curing agent .β ray knocks the polymer chain & bond brakes which generates free radical. This free radical links & crosslinking happens. Chemical cured cables are flexible compare to E-beam cured cable & used in moving application .E-beam cured cables are less flexible which is used in fixed application. E-beam curing cable can be used at high operating temperature up to 250 °C. Chemical curing cables normally archives up to 90°C. operating temperature. E-beam cured cable can manufactured in low thickness & weight compare to chemical curing cables as no curing agent added. Maximum number of polymer like Nylon, PVC, and ETFE including polyolefin can be crosslinked by beam. Nylon, PVC & ETFE cannot crosslinked by chemical curing.
