Problems solved by technology

[0002] The current cables are used more and more widely, so that the cables will be applied in various complex environments, and the cables are required to have various resistance properties. The existing technology does not have good fire resistance. In case of fire or special In the environment where fire resistance is required in production, the cable is easy to melt, exposing the conductor, causing electronic accidents or electronic failures

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] Such as figure 1 As shown, a copper-sheathed mineral insulated fire-resistant cable of the present invention includes a conductor 1, an inorganic ceramic powder insulating layer 2 covering the conductor 1, a copper sheath 4, and an oxygen-insulating and corrosion-resistant sheath 5. Among them, the inorganic ceramic powder insulating layer 2 is an insulating layer made of inorganic ceramic powder, which has the advantages of good insulation, high wear resistance, good corrosion resistance and fire prevention, etc., so that the cable can be heat-resistant and resistant Corrosion and insulation are good; the copper sheath 4 can avoid the exposure of the conductor 1, and the price is cheap, suitable for large-scale production. The oxygen-insulating and corrosion-resistant sheath 5 further improves the corrosion resistance of the cable and isolates o...

Abstract

The invention relates to a cable, in particular to a copper-sheathed mineral insulation fire-resistant cable, aiming at solving a technical problem of providing the copper-sheathed mineral insulation fire-resistant cable with good fire-resistance and corrosion resistance; the copper-sheathed mineral insulation fire-resistant cable comprises a conductor as well as an inorganic ceramic power insulation layer, a copper sheath and an oxygen insulation and corrosion-resistant sheath, which are covered on the conductor sequentially; the oxygen insulation and corrosion-resistant sheath is made from hydroxyapatite ceramics; and a waterproof barrier layer is arranged between the inorganic ceramic power insulation layer and the copper sheath and made from polyvinyl chloride. The copper-sheathed mineral insulation fire-resistant cable has the effects of good fire-resistance and insulation and is waterproof and corrosion-resistant and the like.

Description

technical field [0001] The invention relates to a cable, in particular to a copper-sheathed mineral insulated fire-resistant cable. Background technique [0002] The current cables are used more and more widely, so that the cables will be applied in various complex environments, and the cables are required to have various resistance properties. The existing technology does not have good fire resistance. In case of fire or special In the environment where fire resistance is required for production, the cable is easy to melt, exposing the conductor, causing electronic accidents or electronic failures. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a copper-sheathed mineral insulated fire-resistant cable with good fireproof performance and corrosion resistance. [0004] The technical solution adopted by the present invention to solve the technical problem is: a copper-sheathed mineral insulated fire-resistant cabl...
