Problems solved by technology

[0002] Cables and wires are the medium for transmitting electric energy. Cables are widely used in various fields, involving people's lives and industrial production. Each field has different quality requirements for cables. Some important fields have particularly high quality requirements for cables, otherwise they cannot meet It is necessary and may cause inconvenience to the work. In the field of coal mines, the cables are not easy to be replaced frequently, and the life of the cables should be long.

specific Embodiment approach

[0010] Specific embodiments: the metal hose is a galvanized aluminum alloy metal hose 3, and there are two of them.

[0011] Two galvanized aluminum alloy metal hoses 3 are symmetrically extruded between the silver-plated nickel tape armor layer 6 and the polyvinyl chloride insulating layer 7 inside the cable.

[0012] The galvanized aluminum wire shielding layer 4 is wrapped with a polyperfluoroethylene propylene insulating layer 5, and the polyfluoroethylene propylene insulating layer 5 is wrapped with a silver-plated nickel tape armor layer 6. The silver-nickel tape armor layer 6 is wrapped with a polyvinyl chloride insulating layer 7, and the polyvinyl chloride insulating layer 7 is wrapped with a neoprene sheath layer 8, and the neoprene sheath layer 8 A layer of copper-plastic-aluminum tape polyethylene sheath layer 9 is wrapped.

[0013] Further, the galvanized annealed copper conductor and the galvanized annealed nickel conductor have a cross-sectional diameter of 0.4...

Abstract

The invention discloses a cable with metal hoses for coal. The cable comprises two conductor cores, two metal hoses and six protective layers. The two conductor cores are respectively a galvanized annealing copper conductor core and a galvanized annealing nickel conductor core; the metal hoses are galvanized aluminum alloy metal hoses; from inside to outside, the six protective layers are a galvanized aluminum wire shielding layer, a fluorinated ethylene-propylene insulation layer, a silver-plated nickel tape armored layer, a polyvinyl chloride insulation layer, a polychloroprene sheathed layer and a copper-plastic aluminum tape polyethylene sheathed layer in sequence; the galvanized aluminum wire shielding layer is adopted as the core layer of the cable. The cable has the characteristics of best conductivity, oxidation resistance and ageing resistance; meanwhile, the cable can be widely applied to the fields of coal, petroleum and chemical industry.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a cable with metal hoses for coal mines. Background technique [0002] Cables and wires are the medium for transmitting electric energy. Cables are widely used in various fields, involving people's lives and industrial production. Each field has different quality requirements for cables. Some important fields have particularly high quality requirements for cables, otherwise they cannot meet It is necessary and may cause inconvenience to the work. In the field of coal mines, the cables are not easy to be replaced frequently, and the life of the cables is long. Contents of the invention [0003] In order to increase the practicability of the prior art, the purpose of the present invention is to provide a kind of aging-resistant, oxidation-resistant, strong tensile strength, durable metal hose cable for coal mines. [0004] The present invention is realized by adopting the following technic...
