Description

technical field [0001] The invention relates to an environment-friendly high-conductivity plastic sheath material and a production method thereof, which are suitable for comprehensively penetrating ground wires as conductive plastic sheath materials, and are especially suitable for the penetrating ground where the track circuit section of a railway signal system and cables are laid in the same ditch. The wire is used as the conductive plastic sheath material, and it is also suitable for the integrated grounding system of the railway passenger dedicated line as the conductive plastic sheath material. Electrified railway electric traction return ground wire or ground wire of electrical equipment is used as conductive plastic sheath material. Background technique [0002] In the past, the comprehensive through-ground wire was covered with a layer of lead sheath on the outside of the copper conductor. Because lead is a heavy metal element, it is poisonous and has a high volume d...
