Description

Technical Field

[0001] The utility model relates to the technical field of semi-conductive PE sheaths, in particular to a high-strength and wear-resistant semi-conductive PE sheath material. Background Art

[0002] Semi-conductive PE sheath is a protective outer layer used for cables and electrical equipment, combining semi-conductive properties with the characteristics of polyethylene. It is composed of polyethylene-based materials and conductive materials, has good conductivity and chemical stability, can effectively shield electromagnetic interference and protect the internal components of the cable. This sheath has excellent mechanical strength, wear resistance and weather resistance, and is suitable for use in various environmental conditions.

[0003] During the use of the existing semi-conductive PE sheath, the outer surface of the semi-conductive PE sheath has poor wear resistance, which may cause the outer sheath to be worn or damaged, thereby exposing the internal structure of the conductive PE sheath and increasing the risk of cable damage. The poor wear resistance of the outer sheath may make it difficult to effectively protect the conductive PE sheath, making the cable vulnerable to external physical damage or environmental factors. The worn or damaged outer sheath may affect its insulation performance, resulting in reduced safety of the cable in high-voltage or high-frequency environments. The outer sheath with poor wear resistance may shorten the service life of the cable, requiring more frequent maintenance or replacement, increasing maintenance costs and inconvenience.
