  • Patent number: 4330493
    Abstract: A process for preparing a high voltage-ignition cable having a low electrostatic capacity comprising a resistive-conductor core, an insulator layer and a jacket layer, which comprises preparing a resistive-conductor core comprising a fiber bundle and a semiconductive material provided on at least on the circumferential surface thereof, extrusion coating a polyolefin resin on the circumferential surface of the resistive-conductor core to form an insulator layer, irradiating the insulator layer with electron beam to effect cross-linking of the resin, extrusion coating a polyolefin resin, without providing a reinforcing layer or after providing a reinforcing layer, on the cross-linked insulator to form a jacket and irradiating the jacket with electron beam.
