Abstract
A tough high-flame-retardant oxygen-isolating layer cable for rated voltage equal to and less than 0.6/1kV comprises a plurality of cores which are stranded together, each core comprises a conductor and a low-smoke zero-halogen polyolefin insulating layer arranged outside the conductor, an isolating layer is arranged outside the stranded cores, an oxygen-isolating layer comprising metal hydrate is arranged outside the isolating layer, and a sheath layer is arranged outside the oxygen-isolating layer. The isolating layer of the tough high-flame-retardant oxygen-isolating layer cable adopts a high-flame-retardant fire-insulating glass fabric lapping tape for lapping and is filled with mineral insulating material, and therefore the tough high-flame-retardant oxygen-isolating layer cable has a fireproof effect and better bending property. The oxygen-isolating layer of the tough high-flame-retardant oxygen-isolating layer cable, which is arranged outside the isolating layer, has high-flame-retardant property.
Description
Technical field
The utility model relates to a kind of power transmission cable; Relate in particular to a kind of rated voltage 0.6/1kV and following toughness high flame retardant oxygen barrier layer cable, it is specially adapted to the place that airport, subway, harbour, tunnel, power station, hotel, theater, television tower, petrochemical industry, skyscraper etc. have high flame retardant to require to cable.
Background technology
Cable is to be processed by the conductor outsourcing insulation and the protective layer of one or more mutually insulated, with electric power or information from one be transferred to another place lead.
The common construction of cable is to be employed in conductor to extrude one deck polyvinyl chloride insulation layer or rubber-covered restrictive coating outward, thermo-labile, the easy firing of the cable of this kind structure, and when burning, produce toxic gases such as a large amount of toxic smoke mists and hydrogen chloride.
Existing high flame retardant oxygen barrier layer cable also exists: 1, be not suitable for the design and the manufacturing of soft junction structure cable.2, because the oxygen barrier layer that metal hydrate is formed is extruded on the cable core of cable the puncture thereby the insulating barrier of the cable that causes easily makes moist closely when carrying out withstand voltage test.
The utility model content
To the problems referred to above, the purpose of the utility model is to provide a kind of rated voltage 0.6/1kV and following toughness high flame retardant oxygen barrier layer cable, to solve problems of the prior art.
To achieve these goals, the technical scheme of the utility model is following:
Rated voltage 0.6/1kV and following toughness high flame retardant oxygen barrier layer cable; It is characterized in that; Comprise the some heart yearns that twist together, said heart yearn comprises the low-smoke halogen-free polyolefin insulating barrier that conductor is outer with being arranged on conductor, and said heart yearn after stranded is outside equipped with separator; Said separator is outside equipped with the oxygen barrier layer of being made up of metal hydrate, and said oxygen barrier layer is outside equipped with restrictive coating.
In an embodiment of the utility model, the gap location between said separator and the heart yearn is provided with packed layer.
In an embodiment of the utility model, said heart yearn has three.
In an embodiment of the utility model, said separator is the wrapped high flame retardant fire insulation glass cloth band of employing, and is equipped with the fire lagging that mineral insulating material is filled.
The separator of the utility model is to adopt wrapped high flame retardant fire insulation glass cloth band, and is equipped with mineral insulating material and fills, and therefore not only have the fireproof effect, and bending property is better.
The oxygen barrier layer of the utility model is arranged on outside the separator, has high flame resistance.
The utility model is specially adapted to the place that airport, subway, harbour, tunnel, power station, hotel, theater, television tower, petrochemical industry, skyscraper etc. have high flame retardant to require to cable.
Description of drawings
Specify the utility model below in conjunction with accompanying drawing and embodiment:
Fig. 1 is the structural representation of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, rated voltage 0.6/1kV and following toughness high flame retardant oxygen barrier layer cable comprise the some heart yearns that twist together, and in the present embodiment, heart yearn has three.
Heart yearn comprises the low-smoke halogen-free polyolefin insulating barrier 2 that conductor 1 is outer with being arranged on conductor, and conductor 1 is a copper conductor.The low-smoke halogen-free polyolefin insulating barrier has favorable mechanical physical property and fire resistance, and the amount of being fuming is little during fire, flue gas toxity is low.
Heart yearn after stranded is outside equipped with separator, and the gap location between separator 4 and the heart yearn is provided with packed layer 3.Separator 4 is the wrapped high flame retardant fire insulation glass cloth band of employing, and is equipped with the fire lagging that mineral insulating material is filled, and not only have the fireproof effect, and bending property is better.
The utility model is specially adapted to the place that airport, subway, harbour, tunnel, power station, hotel, theater, television tower, petrochemical industry, skyscraper etc. have high flame retardant to require to cable.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The just principle of describing in the foregoing description and the specification of the utility model; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the scope of the utility model that requires protection.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
