Abstract
The utility model provides a mineral insulated flexible fire-proof cable and belongs to the technical field of cables. The quality of the fire-proof cable is improved. The mineral insulated flexible fire-proof cable comprises an outer sheath, the outer sheath is internally provided with a copper sheath, the copper sheath is internally provided with a plurality of bundles of conducting wires, each bundle of conducting wire is sequentially coated with an inner insulating layer and an outer insulating layer, and filler is arranged between the outer insulating layers and the copper sheath. The mineral insulated flexible fire-proof cable has the advantage that the cable has good waterproof performance, can be bent by a large margin and is made of environmental protection material.
Description
Technical field
The utility model belongs to the cable technology field, refers in particular to a kind of mineral insulating flexible fireproof cable.
Background technology
Development along with the comprehensive wiring industry, especially the rise of data center, people more and more pay attention to data safety, cable is as the highway of communication, it naturally just becomes the popular domain of various countries engineer research in the middle of transmitting procedure for the resistance ability of outburst disaster, as the fire prevention first of comprehensive wiring " three is anti-", also just become the most important thing.
Summary of the invention
The purpose of this utility model is to provide a kind of mineral insulating flexible fireproof cable, and it still can effectively work a period of time under hot environment, and structural design has reduced production cost compared to prior art, has improved the flexibility of cable.
The purpose of this utility model is achieved in that
A kind of mineral insulating flexible fireproof cable, comprise oversheath, it is characterized in that: be provided with copper sheath in described oversheath, be provided with some bundle wires in copper sheath, every bundle wire outside is all wrapped and is provided with inner insulating layer and external insulation layer successively, between described external insulation layer and copper sheath, is provided with filler.
In above-mentioned a kind of mineral insulating flexible fireproof cable, described inner insulating layer is: the wrapped multi layer cloud master tape composite insulation layer that is provided with in the wire outside, the number of plies of described multi layer cloud master tape is 3 layers to 6 layers.
In above-mentioned a kind of mineral insulating flexible fireproof cable, described external insulation layer is: wrapped one deck or the two layers of fire-resistant composite band of being provided with in the inner insulating layer outside.
In above-mentioned a kind of mineral insulating flexible fireproof cable, described filler is the Halogen mineral wool rope.
In above-mentioned a kind of mineral insulating flexible fireproof cable, described copper sheath is: the wrapped rear welding of copper strips forms copper pipe, and the outer surface of copper pipe is provided with the continuous external screw thread formed by embossing.
In above-mentioned a kind of mineral insulating flexible fireproof cable, described oversheath is to adopt the low-smoke halogen-free flame-retardant sheath material to make.
The utility model outstanding and useful technique effect compared to existing technology is:
1, the mass defect that easily produces when existing common magnesium oxide insulated cable can not be crooked, crooked of the present utility model, this cable copper sheath is processed through embossing and special process, Cable Bending Radius can reach 30 times of cable sizes, is convenient to mounting and installation.
2, the utility model adopts mica tape and fire-resistant composite band is wrapped has replaced traditional magnesium oxide powder, can effectively prevent cable service quality problem, and the insulation resistance reliability improves.Cable material cost and production cost also reduce by 20% left and right simultaneously.Can be in museum, the important events such as library, hospital vigorously promote the use.
3, the whole construction of cable of the present utility model all adopts environment-friendly materials, is occurring that fire incident does not produce toxic and harmful.
4, water resistance of the present utility model is better, can be smoothly by the circuit integrity test under the watering state.Be subject under fiery 950 ℃, waterproof test can be passed through smoothly.Can bear under the simulated fire condition and knock impulse withstand test simultaneously.
