Problems solved by technology

[0002] There are many varieties of existing power cables, mainly composed of conductors, insulating layers on the surface of conductors, and the outermost outer sheath. The requirements for wear resistance and wear resistance are getting higher and higher, especially for power cables used in downhole operations. Due to the long-term work in the downhole, there are many lines, their tear resistance and wear resistance are relatively poor, and the cost is high.

The sheath layer is prepared from the following raw materials in parts by weight: 15-25 parts of polytetrafluoroethylene, 40-60 parts of ethylene-vinyl acetate copolymer, 10-18 parts of polyvinyl chloride, 1-2 parts of epoxidized linseed oil, 0.4-1 part of coal tar, 8-12 parts of Turkey red oil composite corn cob, 10-15 parts of zeolite powder, 15-25 parts of white carbon black, 4-8 parts of liquid epoxy resin, 4-8 parts of nano graphene, 3-6 parts of polyethylene vinyl acetate, 3-7 parts of clay, 4-8 parts of kaolin, 2-5 parts of phenolic resin, 2-4 parts of vulcanizing agent TMTD (tetramethyl thiuram disulfide), 1-2 parts of dicumyl peroxide, 0.7-1.1 parts of antioxidant 1076, 0.4-1.2 parts of antioxidant 1035 and 1.5-2.5 parts of antioxidant 1010.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a wear-resistant and tear-resistant power cable. Background technique [0002] There are many varieties of existing power cables, mainly composed of conductors and insulating layers on the surface of conductors and the outermost outer sheath. The requirements for wear resistance and wear resistance are getting higher and higher, especially for power cables used in downhole operations. Due to long-term work in the downhole, there are many lines, their tear resistance and wear resistance are relatively poor, and the cost is high. How to improve the tear resistance and wear resistance of power cables and reduce their cost has become a technical problem that needs to be solved at present. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a wear-resistant and tear-resistant power cable, which has excellent...
