Abstract

The utility model relates to the field of cables, and in particular relates to a compression resistance and collision resistance cable with a buffer layer. The cable comprises a cable body. The cable body comprises a cable inner core. An insulating inner layer is arranged outside the cable inner core. A number of compression resistance and collision resistance sleeves are uniformly sheathed outside the insulating inner layer. A rubber insulating layer is arranged outside the compression resistance and collision resistance sleeves. The rubber insulating layer is coated with a waterproof coat layer. Each compression resistance and collision resistance sleeve is composed of a sleeve rubber and plastic outer layer, a sleeve rubber and plastic inner layer and steel return springs. An annular cavity is formed between the sleeve rubber and plastic outer layer and the sleeve rubber and plastic inner layer. Four steel return springs are uniformly arranged in the circumferential direction of the annular cavity. The annular cavity is filled with polyvinyl chloride rubber. According to the utility model, the cable is simple in structure and is able to withstand the compression or the collision of a great external force; the cable is protected from being damaged; the state property loss is reduced; and the power transmission security is ensured.

Description

A kind of crashworthiness of the resistance to compression with resilient coating cable

[technical field]

The utility model relates to field of cables, particularly a kind of crashworthiness of the resistance to compression with resilient coating cable.

[background technology]

Cable, as the carrier of electric power transfer, because Naked exposes outside, therefore will be subject to the impact of environment, once cable is oppressed or is clashed into be prone to and damages or fracture, not only make electric power transportation interrupt, cause ten million or factory and enterprise influenced, also cause the loss of national wealth.

Therefore be necessary existing cable is carried out to technological innovation further.

[utility model content]

The purpose of this utility model is for the defect of prior art and deficiency, provide a kind of simple in structure, reasonable in design, a kind of crashworthiness of the resistance to compression with resilient coating cable easy to use, it adopts an insulating barrier is set outside cable core, even sheathed some anti-collision barrel covering devices against pressure outside insulating barrier, outside crashproof circle ring device against pressure, a rubber insulation is set, rubber insulation outer wrapping waterproof outer cortex, it has simple in structure, can stand compressing or the shock of larger external force, thereby the protection cable is not damaged, reduce the national wealth loss, and assurance electric power transfer safety.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of crashworthiness of the resistance to compression with resilient coating cable described in the utility model, it comprises cable body, and described cable body comprises the cable inner core, and described cable inner core arranges an inner insulating layer outward; Described inner insulating layer evenly is arranged with some crashproof jacket casings against pressure outward, and described crashproof jacket casing against pressure is outside equipped with rubber insulation; Described rubber insulation is wrapped with the waterproof watch cortex; Described crashproof jacket casing against pressure is comprised of jacket casing rubber and plastic skin, jacket casing rubber and plastic internal layer and rigidity returning spring, form toroidal cavity between described jacket casing rubber and plastic skin and jacket casing rubber and plastic internal layer, this toroidal cavity circumferencial direction evenly is provided with four rigidity returning springs, filling polyvinyl chloride rubber in this toroidal cavity.

Further, be enclosed with fire resistant coating on described rigidity returning spring surface.

After adopting said structure; the utility model beneficial effect is: a kind of crashworthiness of the resistance to compression with resilient coating cable described in the utility model; it adopts an insulating barrier is set outside cable core; even sheathed some anti-collision barrel covering devices against pressure outside insulating barrier; outside crashproof circle ring device against pressure, a rubber insulation is set; rubber insulation outer wrapping waterproof outer cortex; it has simple in structure; can stand compressing or the shock of larger external force; thereby the protection cable is not damaged; reduce the national wealth loss, and guarantee electric power transfer safety.
