Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a high temperature resistant and flame retardant cable. Background Art

[0002] Cables are widely used and are closely related to people's work and life. Cables generally include a conductor core, an insulation layer, a filling layer and a flame-retardant outer sheath from the inside to the outside. Flat cable or ribbon cable is a type of cable. It is a flat conductor formed by combining many wires together. This type of cable has low cost, light weight, strong toughness, and is easy to use in large and small equipment. Elevator flat cables integrate control, communication, and video functional cores.

[0003] Application No. 202121983403.4 discloses a high-temperature resistant and heat-insulated flame-retardant cable. During the use of a high-temperature resistant and heat-insulated flame-retardant cable, when the staff transports and lays the cable, the inner ring sleeve and the outer ring sleeve both play a shaping role, supporting the inside of the cable to ensure that the cable will not be flattened, and the elastic buffer block has a certain resilience. When impacted or squeezed, it will rebound quickly to provide buffering protection for the cable core, so that the cable can be used normally, and the insulating layer and the first shielding layer wrap the cable core. The insulating layer will ensure that there will be no short circuit between the cable cores. The first shielding layer can shield the electromagnetic interference between the cable cores, so that the cable cores do not interfere with each other. At the same time, the second shielding layer protects all the cable cores on the outside to ensure that there will be no external The electromagnetic wave affects the cable core, and the double-layer protection can fully isolate the cable core; the inner flame retardant layer protects the single cable core to avoid spontaneous combustion of the cable under long-term load use, and the outer flame retardant layer and fire retardant coating are arranged on the outermost side of the cable, which improves the fire resistance of the cable. When a fire occurs in the external environment, the fire source is blocked to ensure that the cable will not burn. The inner flame retardant layer, the outer flame retardant layer and the fire retardant coating have a flame retardant effect on the cable from the inside and outside at the same time, which fully improves the service life of the cable, prolongs people's fire handling time, and reduces the loss of fire. At the same time, the thermal insulation layer plays a role of heat insulation to ensure that the external environment temperature will not affect the normal use of the cable, and the thermal insulation layer is made of rubber and plastic material, which has a certain moisture-proof effect, so that moisture will not enter the cable.

[0004] The flame retardant cable has a flame retardant effect on the cable from the inside and outside by arranging a flame retardant layer, an outer flame retardant layer and a fire retardant coating on the surface and inside of the cable. However, the flame retardant layer of the cable protects the internal wire core from the outside, resulting in ineffective protection against spontaneous combustion. Therefore, a high temperature resistant and heat-insulating flame retardant cable is needed. Utility Model Content
