Cable for linkage action of intelligent emergency lighting system power distribution device

Abstract

The invention relates to a cable for linkage action of an intelligent emergency lighting system power distribution device. The cable comprises a plurality of wire cores; the plurality of wire cores are twisted with each other, gaps are filled with a flame-retardant PP rope filling layer to form a round cable core, the outer layer of the cable core is longitudinally wrapped with an aluminum plastictape and a polyethylene moisture-proof layer in sequence, and a galvanized steel wire braided outer sheath is arranged outside the polyethylene moisture-proof layer. Each wire core structurally comprises a plurality of strands of copper conductors, a fireproof coating layer is coated outside the plurality of strands of copper conductors, and a high-temperature fireproof belt is wrapped outside the fireproof coating layer. And the fireproof coating layer is coated on the outer layer of the multi-strand copper conductors by adopting a fireproof coating material. The number of the wire cores is2-4. According to the invention, the cable is ensured to satisfy the performances of high temperature resistance, moisture resistance, fire resistance, interference resistance, explosion prevention and the like, and the performance of reliably, rapidly and accurately transmitting signals to an emergency lighting lamp is realized.

Description

technical field [0001] The invention relates to the technical field of cable equipment, in particular to a cable for chain action of distribution electrical devices of an intelligent emergency lighting system. Background technique [0002] When a fire occurs, the general municipal power supply is cut off, and the emergency lighting system of the fire-fighting equipment provides light sources for personnel to escape. The distribution device of the emergency lighting system controls the working status of the emergency lighting fixtures on each floor, so its action chain circuit is required to be reliable, accurate, fast and safe in the harsh environment so that each emergency lighting fixture can be chained in time; the existing In terms of technology, the stability of the action chain circuit of the distribution device of the emergency lighting system in extreme environments and the performance of fast delivery need to be improved. Contents of the invention [0003] Aiming...
