An isolated aluminum alloy fire-resistant cable

Abstract

The invention relates to cables, particularly to an isolation type aluminum alloy fire-resistant cable. The isolation type aluminum alloy fire-resistant cable is of an isolation type and is high in wear-resistant performance. The isolation type aluminum alloy fire-resistant cable comprises four insulating inner isolation cores, a ceramic fire-resistant coating layer and a low-smoke zero-halogen polyolefin sheath, wherein the ceramic fire-resistant coating layer and the low-smoke zero-halogen polyolefin sheath sequentially covers the four insulating inner isolation cores; every insulating inner isolation core is composed of a conductor, an insulating layer and an extruded aluminum tube protecting jacket, wherein the insulating layer and the extruded aluminum tube protecting jacket sequentially sleeve the conductor; an inorganic fire-resistant isolating layer is arranged between the four insulating inner isolation cores and the ceramic fire-resistant coating layer; an inorganic mineral fire-resistant isolating layer is arranged between the ceramic fire-resistant coating layer and the low-smoke zero-halogen polyolefin sheath. The isolation type aluminum alloy fire-resistant cable has the advantages of obtaining high fire resistance and isolation, avoiding exposure of the inner cores by means of the protecting jacket and accordingly avoiding accidents, and further obtaining waterproof performance.

Description

technical field [0001] The invention relates to a cable, in particular to an isolated aluminum alloy fire-resistant cable. Background technique [0002] The current cables are used more and more widely, so that the cables will be applied to various complex environments, and the cables are required to have various resistance properties.
