Problems solved by technology

However, the existing inorganic insulated cables also have some shortcomings. For example, the inorganic filling layer usually needs to be wrapped around the cladding or the outer sheath. The limitations of the material properties of the wrapping layer and the outer sheath itself affect the insulation of the inorganic filling layer , heat and fire resistance

Embodiment Construction

[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0015] Such as figure 1 with figure 2 The shown flexible inorganic insulated fire-resistant cable is composed of one or more conductors 2, an inorganic filling layer 1, and a sheath layer 3 from the inside to the outside. The sheath layer 3 is made of a metal material and is provided with corrugations. 4. Specifically, the material of the conductor 2 is copper, aluminum or aluminum alloy, the material of the sheath layer 3 is copper, aluminum or aluminum alloy; the material of the inorganic filling layer 1 is metal oxide; preferably, the inorganic material The material filling layer 1 is magnesium oxide. In a further improvement, the mate...

Abstract

The invention discloses a flexible inorganic insulating fire-resisting cable. The flexible inorganic insulating fire-resisting cable is composed of one piece or a plurality of pieces of conductors, an inorganic substance packing layer and a sheathing layer from inside to outside in sequence, wherein the sheathing layer is made of metal materials and provided with ripples. According to the flexible inorganic insulating fire-resisting cable, conventional organic substances of plastics, rubber and the like are not adopted as an insulating sheath, inorganic substances with good insulating performance are adopted as an insulating layer instead, metal materials of copper, aluminum or aluminum and the like are used as conductors and adopted by the sheathing layer, and the defects that a metal sheath is uneasy to bend, install and transport are overcome through rippling process.

Description

Technical field [0001] The invention relates to the technical field of cable processing and manufacturing, in particular to a flexible inorganic insulated fire-resistant cable. Background technique [0002] Inorganic insulation cable is a type of cable that uses inorganic filling as the insulation layer. It has superior insulation performance and has heat and fire resistance that conventional plastic or rubber insulation cannot match. However, the existing inorganic insulated cables also have some shortcomings. For example, the inorganic filling layer usually needs to be wrapped around the sheath or the outer sheath. The limitations of the material properties of the surrounding sheath and the outer sheath affect the insulation of the inorganic filling layer. , Heat and fire resistance performance. Summary of the invention [0003] The purpose of the present invention is to provide a flexible inorganic insulation fire-resistant cable, which does not use conventional plastics and r...
