Embodiment

[0015] Example: such as figure 1 As shown, in the flexible cable described in this embodiment, the copper core stranded conductor 1 adopts the second type of structure conductive core; It can make the cable have fire resistance and make the cable move better; the filling layer 3 uses a flame-retardant filling rope, and its function is to ensure the flame retardancy and roundness of the cable; the wrapping layer uses mica tape to wrap around the wrapping layer 4 and glass fiber tape Wrapping layer 5, the production form adopts overlapping wrapping, and the covering rate is not less than 15%. It is mainly used to tighten the cable core and isolate the armor layer; the armor layer 6 uses copper sleeve threads, which have two functions , one is to play the role of anti-compression, to protect the core from being crushed by external pressure; the other is to prevent the fire source from entering the cable core directly when the cable catches fire, and to play a role in fire prevent...

Abstract

The invention discloses a flexible cable which integrates the wear-resistant function, the flame retardant function, the fire prevention function, the high temperature and low temperature resistant function, the acid and alkali resistant function, the oil and water resistant function, the tearing prevention function and the good and stable signal transmission function. The flexible cable is composed of copper core stranded conductors, an insulating layer, a packing layer, a wrapping tape layer, an armor layer and a protective sleeve layer from inside to outside. The second type of copper core conductors are adopted for the copper core stranded conductors, mica tape is wound to form the insulating layer, flame-retardant filling ropes are adopted for materials of the packing layer, the wrapping tape layer comprises a mica tape wrapped layer and a glass fiber belt wrapped layer, and 125 DEG C low-smoke halogen-free flame retardant TPU materials are adopted for materials of the protective sleeve layer. The flexible cable is suitable for being applied to industrial and mining enterprises such as electricity generation enterprises, metallurgy enterprises, electronic enterprises, automobile enterprises, petroleum enterprises, chemical industry enterprises and large-scale construction enterprises, and the flexible cable can meet the requirements for the abrasion resistance performance, the fire prevention performance and other types of performance of cables, and can be used in special environments such as high-temperature environments, low-temperature environments, acid environments, alkali environments and environments where movement exists.

Description

technical field [0001] The invention relates to the technical field of cable processing and manufacturing, in particular to a flexible cable that has the functions of wear resistance, flame retardancy, fire prevention, high and low temperature resistance, acid and alkali resistance, oil and water resistance, tear resistance and good and stable signal transmission functions. . Background technique [0002] Cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, aluminum alloy cables, etc. Composition, used to connect circuits, electrical appliances, etc. At present, there are many fire-resistant and high-temperature-resistant cables in the market, but the moving wear resistance of the cables is insufficient, and the cables are often damaged during the long-term moving and dragging process, which will bring inconvenience to some units. For...
