Abstract
The utility model relates to the cable field and specifically relates to a fire-proofing cable having multiple fire-proofing layers. The fire-proofing cable comprises a fire-proofing cover layer and a cable body. The cable body is externally sleeved with the fire-proofing cover layer. A dovetail groove is arranged in the upper part of the cable body. The fire-proofing cover layer is arranged outside the cable body and is composed of an outer fire-proofing asbestos layer, an intermediate fire-proofing foamed cement thin layer, and an inner insulating rubber layer. A dovetail clamping head matched with the dovetail groove is arranged in the upper part on the inner wall of the inner insulating rubber layer, thereby guaranteeing that the fire-proofing cover layer is conveniently and firmly arranged on the cable body. The fire-proofing cable is simple in structure and convenient to operate, and the fire-proofing performance of the cable is improved, so that the electric power transmission is guaranteed to be unblocked and potential safety hazards brought by ignition of electric wires are reduced.
Description
[technical field]
The utility model relates to field of cables, particularly a kind of fireproof cable with multiple fireprotection layer.
[background technology]
Cable is widely used in all trades and professions as the carrier of electric power transportation; But there are disaster hidden-trouble or fire-prone or the location that takes place frequently or area at some, for example mine, training of qi ， oil refining factory etc. use common cable because not preventing fires, and easily bring loss to enterprise, perhaps because fire causes power breakdown, thereby bring potential safety hazard to shop floor worker.
So be necessary the existing construction of cable is carried out further technological innovation.
[utility model content]
The purpose of this utility model is for the defective of prior art and deficiency, provide a kind of simple in structure, reasonable in design, a kind of fireproof cable with multiple fireprotection layer easy to use, it adopts cable body top that one dovetail groove is set, one flameproof enclosure layer is set outside cable body, this flameproof enclosure layer is by outer fire-proof asbestos layer, intermediate layer fire prevention foamed cement thin layer and primary insulation rubber layer, and in primary insulation rubber layer upper inside wall the one dovetail dop that matches with dovetail groove is set, guarantee firmly to be arranged on the cable body with convenient this flameproof enclosure layer, it has simple in structure, easy to operate, improved the fireproofing of cable ability, thereby guaranteed the unimpeded of electric power transportation and reduced the potential safety hazard of catching fire and bringing because of electric wire.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of fireproof cable with multiple fireprotection layer described in the utility model, it comprises flameproof enclosure layer and cable body, described cable body is arranged with the flameproof enclosure layer outward.
Further, described flameproof enclosure layer comprises asbestos layer, foamed cement thin layer and insulating cement cortex, and described flameproof enclosure layer is the barrel shape of both ends open, and this flameproof enclosure layer is disposed with asbestos layer, foamed cement thin layer and insulating cement cortex from outside to inside.
Further, described cable body top is provided with dovetail groove.
Further, described flameproof enclosure layer upper inside wall is provided with the dovetail dop that matches with cable body top dovetail groove.
After adopting said structure, the utility model beneficial effect is: a kind of fireproof cable with multiple fireprotection layer described in the utility model, it adopts cable body top that one dovetail groove is set, one flameproof enclosure layer is set outside cable body, this flameproof enclosure layer is by outer fire-proof asbestos layer, intermediate layer fire prevention foamed cement thin layer and primary insulation rubber layer, and in primary insulation rubber layer upper inside wall the one dovetail dop that matches with dovetail groove is set, guarantee firmly to be arranged on the cable body with convenient this flameproof enclosure layer, it has simple in structure, easy to operate, improved the fireproofing of cable ability, thereby guaranteed the unimpeded of electric power transportation and reduced the potential safety hazard of catching fire and bringing because of electric wire.
