Problems solved by technology

[0004] Ordinary mobile cables are used. Although the cable has good bending performance and is convenient to lay, but there is no reinforcement inside, the cable is very easy to be damaged during the rolling process, which will affect the use.
The metal armored cable is very outstanding in terms of anti-rolling performance, but its weight is heavy, and its bending performance is very poor, which is inconvenient to lay, and the cost of metal armored cables is relatively high.

Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] like figure 1 As shown, a drag-resistant and rolling-resistant mobile cable according to the present invention includes a cable core, the cable core is wrapped around a tape layer 5, and the outermost layer is extruded into an outer sheath 6; the cable core is composed of It is composed of several insulated wire cores and saddle-shaped filling strips separating the insulated wire cores; the insulated wire core is composed of a conductor 1 and an insulating layer 2 extruded outside the conductor 1 .

[0018] The saddle-shaped filling strip is composed of the central aramid yarn 3 and the saddle-shaped rubber strip 4 extruded outside the aramid yarn; the saddle-shaped rubber strip 4 is provided with a plurality of rubber band ridges, and every two rubber bands A groove is formed between the ridges to separate the insulated cores;

[0019] The conductor 1 is fo...

Abstract

The invention discloses a dragging-resistant grinding-resistant mobile cable. The dragging-resistant grinding-resistant mobile cable comprises a cable core, a cable core wrapped belt layer, an outermost layer wrapped outer protective sleeve, wherein the cable core consists of a plurality of insulated cable cores and a saddle-shaped filling strip for isolating the insulated cable cores; each insulated scale core consists of a conductor and an insulated layer wrapped outside the conductor. The dragging-resistant grinding-resistant mobile cable is high in softness, high in bending resistance, high in tensile performance and dragging resistance, and can be completely suitable for characteristics of being frequent to move, easy to grind, and the like.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a drag-resistant and rolling-resistant mobile cable. Background technique [0002] Mobile cables are used in a wide range of occasions, and are most widely used in construction and industry. In actual use, cables are often laid in places without fixed cable troughs. On the construction site, such cables need to be replaced according to different usage conditions. , and the way of laying is artificial, so this kind of cable needs to have good bending performance and good dragging performance. When the cable is used on the construction site, it will inevitably be crushed by people, vehicles or other equipment, so the cable must be resistant to crushing. In order to ensure the above requirements, in the process of use, the environment where ordinary cables are used is mainly achieved by strengthening management and using cables carefully. In some places, metal armored cables are us...
