Problems solved by technology

[0003] Although the cable sheath has good anti-aging and oxidation resistance, the insulation layer of the cable core has poor anti-aging and oxidation resistance, and its use has certain limitations. Therefore, we propose an oxidation-resistant cable and its production method to solve the above problems

Abstract

The invention discloses an oxidation-resistant cable and a production method thereof, the cable including a conductor, a shield, an insulation layer and an outer sheath, the shield is arranged on theouter surface of the conductor, the insulation layer is located outside the shield, and a fill layer is arranged between the insulation layer and the outer sheath. a water blocking tape is arranged between the fill layer and the outer sheath; the insulation layer takes polypropylene as a base material, supplemental polyolefin elastomer POE, antioxidant 1010, 168 and magnesium oxide crosslink polyethylene nanocomposites are also used, polypropylene has high impact resistance and mechanical toughness and is resistant to various organic solvents and acid-base corrosion and is strongly heat-resistance, flame-resistant and acid and alkli-resistant, and the polyolefin elastomer POE enhances the strength and toughness of polypropylene. The addition of magnesium oxide crosslinked polyethylene nanocomposites improves the thermal properties of polypropylene, and good heat resistance and oxidation resistance are guaranteed. The antioxidant can delay the oxidation degradation of tree materials.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to an oxidation-resistant cable and a production method thereof. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of conductors (at least two in each group). Each group of conductors is insulated from each other and is often twisted around a center. Insulating covering. The cable has the characteristics of internal electrification and external insulation. The cable mainly consists of an internal cable core, an insulating layer covering the cable core, and a sheath. The sheath plays a protective role. Currently, the sheath materials used in the market have low raw material costs, high insulation properties, and small dielectric loss. , Strong signal transmission performance, and simple preparation method, for example: HDPE has high material density, good crystallinity, high crystallinity, strong interlayer force, g...
