Problems solved by technology

[0002] Nowadays, the requirements for cables are getting higher and higher, and there are strict requirements for the anti-aging performance and wear resistance of cables. However, it is difficult for traditional cables to meet the current use requirements in terms of anti-aging performance and wear resistance, especially when the Waterproof, flame retardant, and occasions that need to be moved and dragged, a new type of cable is urgently needed to meet these requirements

Embodiment Construction

[0008] Below in conjunction with accompanying drawing, the present invention will be further described;

[0009] Such as figure 1 As shown, a mobile tensile cable is composed of an active power core, an alloy lead sheath shielding layer 7, a steel clad armor layer 8 and a silicone rubber outer sheath 9, and the active power core is made of natural butyl The styrene rubber insulating layer 3 is extruded and wrapped on four closely extruded aluminum alloy conductors 1, and a flame-retardant filling rope 2 is arranged in the gap in the main power line core; the water-blocking tape is wrapped around the cladding layer 6 to wrap three main power conductors. The wire core is a cable core; the gap in the cable core is provided with a foam rubber filling layer 4, and three tensile steel wires 5 are evenly arranged in the foam rubber filling layer 4; the alloy lead sheath shielding layer 7, steel ladle The armor layer 8 and the silicone rubber outer sheath 9 are extruded on the outsi...

Abstract

The invention discloses a movable tensile cable. The movable tensile cable is composed of main power cable cores, a lead alloy shielding layer, a steel belting armor layer and a silicon rubber outer sheath, wherein each main power cable core is formed by extruding and wrapping a natural butylbenzene rubber insulation layer around four tightly extruded aluminum alloy conductors; gaps inside each main power cable core are filled with inflaming retarding filling ropes; a water-blocking tape wrapping layer wraps the three main power cable cores to form a cable core; a foamed rubber filling layer is arranged inside gaps in the cable core; three tensile steel wires are evenly arranged inside the foamed rubber filling layer; the lead alloy shielding layer, the steel belting armor layer and the silicon rubber outer sheath are sequentially wrapped around the cable core from inside to outside. The natural butylbenzene rubber serves as the sheath, ageing resistance and abrasive resistance are enhanced, and meanwhile the cable has the advantages of being fireproof, resistant to water, good in shielding performance, stable in performance and applicable to severe environments where water exists and the cable needs to be moved and dragged.

Description

technical field [0001] The invention relates to cables, in particular to a mobile tensile cable. Background technique [0002] Nowadays, the requirements for cables are getting higher and higher, and there are strict requirements for the anti-aging performance and wear resistance of cables. However, it is difficult for traditional cables to meet the current use requirements in terms of anti-aging performance and wear resistance, especially when the Waterproof, flame retardant, and the occasions that need to be moved and dragged, a new type of cable is urgently needed to meet these requirements. Natural styrene-butadiene rubber has good wear resistance, tensile strength, tear strength and aging resistance, as well as good water resistance and air tightness, and has good use value for fire prevention and water resistance. Contents of the invention [0003] In view of the foregoing, it is an object of the present invention to provide a mobile tensile cable. [0004] The sch...
