Abstract
The utility model discloses a molded-line stranded-conductor environmental-protection cable with high flame resistance, and the cable comprises a conductor which is located at the center of the cable, and also comprises a cross-linked polyethylene insulating layer which wraps the exterior of the conductor in a pressing manner. The conductor and the cross-linked polyethylene insulating layer form an insulating cable core. The exterior of the insulating cable core is wrapped by a flame-retardation tape in the pressing manner, and the flame-retardation tap is wrapped by an aluminum-alloy-tape linkage-armored protection layer. The cable provided by the utility model is low in cost, is good in bendability, is high flame resistance, and is energy-saving and environment-friendly during manufacture.
Description
Technical field
The utility model relates to power cable technical field, particularly a kind of environment protection high flame resistance cable that adopts molded line lay configuration conductor.
Background technology
Along with the proposition of country's " amphitypy three is new " (resource-conserving, environmentally friendly, new technology, new material, new technology), for the development of active adaption country, call, company has researched and developed this kind of molded line stranded conductor environment protection high flame resistance cable.
In industry, by doing compact conductor, reduce the external diameter of finished cable at present, after the outside diameter of cable reduces, under assurance product quality prerequisite, can reduce the use amount of insulation, armouring and sheath material.But at present conductor compacting is generally by pressing mould and carries out round press or by pinch roller production moulding conductor, it presses that coefficient is the highest can only reach 0.90 to use conductor that above-mentioned two kinds of modes produce, but the molded line stranded conductor of producing by this method presses coefficient, can reach 0.95, can reduce conductor diameter approximately 5% meeting under the prerequisite of conductor resistance.The finished cable of making by this technique is compared with conventional conductor structure, can save cable insulation approximately 15%, armoring material 10%, sheath material 10%.
Traditional category-A flame retardant cable is in order to guarantee the fire resistance of finished cable, must use fire-retardant insulation, filling, band, sheath material, some fire proofing all can produce environment and the poisonous and hazardous gas of the mankind as flame-proof PVC insulation and protective cover material after burning.But in this invention, cable material is all environment-friendly materials, can not produce harm to environment and the mankind, and this cable again can be smoothly by the requirement of fire-retardant category-A.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of cost low, and anti-flammability is high, the molded line stranded conductor environment protection high flame resistance cable of energy-conserving and environment-protective while simultaneously manufacturing.
The utility model discloses a kind of molded line stranded conductor environment protection high flame resistance cable, this cable comprises the conductor that is positioned at cable center, is extruded in the crosslinked polyetylene insulated layer of conductive surface; Described conductor, crosslinked polyetylene insulated layer form insulated wire cores; Insulated wire cores extrudes fire-retardant band outward, the outer chain armored protective layer of wrapped aluminum alloy strip of fire-retardant band.
In the utility model, preferably, described conductor is trapezoidal or fan-shaped monofilament is stranded forms by many.
In the utility model, preferably, described insulated wire cores is one.
In the utility model, preferably, described insulated wire cores is many, and many insulated wires are twisted into cable core, at the place, gap of cable core, is provided with packed layer, and packed layer is kraft twine and polypropylene mesh split fibre rope.
In the utility model, preferably, the chain armored protective layer of described aluminum alloy strip is the chain sheathed structure of interior buckle type.
The utility model beneficial effect is:
(1) conductor compacting coefficient is high, can reduce cable finished product external diameter, saves each operation raw material use amount.
The use of (2) 5000 line aluminium alloy lock armo structures, is not used other fire proofings to pass through category-A fire-retardant, and when breaking out of fire, cable LSZH, without injury, is conducive to people's escape to human body.
(3) if use aluminium alloy as cable conductor, cable can save crane span structure when laying.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
Embodiment
Below in conjunction with accompanying drawing and instantiation, the utility model is done further and is explained:
Embodiment 1:
As shown in Figure 1, a kind of molded line stranded conductor environment protection high flame resistance cable described in the utility model, this cable comprise be positioned at cable center by many trapezoidal the or stranded conductor forming 1 of fan-shaped monofilament, be extruded in the crosslinked polyetylene insulated layer 2 outside conductor 1; Described conductor 1, crosslinked polyetylene insulated layer 2 form insulated wire cores; Insulated wire cores extrudes fire-retardant band 4 outward, the chain armored protective layer 5 of the outer wrapped aluminum alloy strip of fire-retardant band 4.
Embodiment 2:
As shown in Figure 2, the present embodiment difference from Example 1 is: insulated wire cores becomes many from one, and many insulated wires are twisted into cable core, at the place, gap of cable core, be provided with packed layer 3, packed layer 3 adopts polypropylene mesh split fibre rope, kraft twine material to fill.
The utility model provides a kind of thinking and method of molded line stranded conductor environment protection high flame resistance cable; method and the approach of this technical scheme of specific implementation are a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.In the present embodiment not clear and definite each component part all available prior art realized.
