Problems solved by technology

[0002] Cables are used in various fields. The use of these cables is affected by the external environment. For example, when the cables are in use, they will generate a lot of heat. The fire resistance and fire resistance performance, in order to achieve the fire resistance performance, so often set up more layers of fire protection layer, the setting of these fire protection layers will affect the heat dissipation capacity of the cable, resulting in poor heat dissipation performance
And once the cable is ignited, it can only be used for fire resistance, and foreign objects cannot be used to extinguish the generated flames.

Abstract

The invention discloses a fire resistant cable, which comprises more than one connector, wherein both sides of each connector are provided with an assembly protrusion, the part between two adjacent connectors is sleeved with a cable outer protective sleeve, two ends of the cable outer protective sleeve are open and respectively sleeve the assembly protrusions between two connectors, the middle ofeach connector is provided with a through hole in a penetrating mode, and core wires of the cable pass through the through hole in the middle of each connector. The composite cable disclosed by the invention has excellent fire resistance, can quickly extinguish the fire by using a slip ring in an emergency while guaranteeing the heat dissipation requirements, and forms a secondary fireproof layeroutside the core wires of the cable so as to increase the flame retardant time.

Description

technical field [0001] The invention relates to a cable, in particular to a fire-resistant cable. Background technique [0002] Cables are used in various fields. The use of these cables is affected by the external environment. For example, when the cables are in use, they will generate a lot of heat. In order to achieve the fire resistance performance, more layers of fire protection layers are often set up. The setting of these fire protection layers will affect the heat dissipation capacity of the cable, resulting in poor heat dissipation performance. And once the cable is ignited, it can only be used for fire resistance, and foreign objects cannot be used to extinguish the resulting flame. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fire-resistant cable, which can achieve good fire-resistant performance while ensuring heat dissipation performance, and can use the slip ring to remove the generated flames...
