An elevator special flat cable with flame retardant function

Abstract

The invention discloses an elevator special flat cable with flame retardant function, include a flat cable body, a cable core is arranged inside the flat cable body, A woven layer is fixedly installedon the outer side of the cable core, A protective sleeve is fixedly mounted on the outer side of the braiding layer, a first insulating layer is arranged on the outer side of the protective sleeve, aflame retardant layer is fixedly mounted on the outer side of the first insulating layer, a heat dissipation layer is fixedly installed on the outside of the fire retardant layer, so that that flameretardant lay is arranged, the flame retardant function is acehived, and a flame retardant fiber is arranged to stop the fire from spreading, fire-retardant adhesive is arranged, so as to avoid largearea burn-out of flat cable body, and reduce the loss, facilitates the maintenance and replacement of the damaged flat cable body, recovers the normal use of the elevator as soon as possible, simultaneously avoids causing serious fire, guarantees the life safety of the user, improves the safety performance of the flat cable body, the fire-retardant glue simultaneously plays the role of bonding, and the heat generated by the cable core is accumulated by setting a cavity.

Description

technical field [0001] The invention relates to the technical field of flat cables for elevators, in particular to a special flat cable for elevators with a flame-retardant function. Background technique [0002] Flat cable or ribbon cable is a flat wire formed by combining many wires. This cable is low in cost, light in weight, strong in toughness, and can be used in large equipment as well as in small equipment. Elevator flat The cable integrates the cores of control, communication and video functions. [0003] At present, the commonly used flat cables have no fire resistance performance. When a short-circuit accident occurs in the flat cable, it is easy to cause the flat cable to catch fire, but the general flat cable cannot prevent the fire from spreading, causing the flat cable to burn out and cause losses. It is easy to cause elevator control and communication interruption. As a result, the elevator cannot be used, causing inconvenience to users. At the same time, a f...

Problems solved by technology

[0003] At present, the commonly used flat cables have no fire resistance performance. When a short-circuit accident occurs in the flat cable, it is easy to cause the flat cable to catch fire, but the general flat cable cannot prevent the fire from spreading, causing the flat cable to burn out and cause losses. It is easy to cause elevator control and communication interruption. As a result, the elevator cannot be used, causing inconvenience to users. At the same time, a fire in the flat cable can easily cause a serious fire and threaten the safety of the user; the flat cable will generate a lot of heat when it is in use, and the heat accumulation cannot be dissipated, resulting in serious heating of the flat cable and damage to the flat cable. , reduce the service life of the flat cable and affect the normal use of the elevator; the shock absorption performance of the flat cable is poor, and it is easy to cause a large deformation of the flat cable during transportation, installation or use, causing the flat cable to break and cause the flat cable The damage cannot continue to be used, resulting in a waste of resources
