Abstract
The utility model belongs to the field of cables, and particularly relates to an aluminium alloy service-entrance power cable for buildings, which is suitable for being fixedly laid in a room, a tunnel and a cable duct and other occasions in a service-entrance way. The aluminium alloy service-entrance power cable comprises at least two cable cores formed by two wire cables, an oxygen isolating layer is arranged outside the cable core, an interlocking armor layer is arranged outside the oxygen isolating layer, a low-smoke zero-halogen jacket layer is arranged outside the interlocking armor layer, a filter is arranged between the oxygen isolating layer and the wire core, the wire core comprises a conductor and an insulating layer outside the conductor, wherein the conductor is an aluminium alloy conductor. The aluminium alloy service-entrance power cable has the advantages of completely meeting the requirements of modern buildings on high electric property, mechanical property, flame retardant property and fire safety property and long service life of the service-entrance cable, and simultaneously can substitute a copper cable, thus saving resources.
Description
Technical field
The utility model belongs to field of cables, specifically is a kind of fixedly be laid in aluminium alloy house lead in power cable for building in places such as indoor, tunnel and cable trough of building house lead in that is applicable to.
Background technology
China is a bauxite resource and the abundant country of rare earth resources reserves, announces that according to the parties concerned aluminium ore reserves are 3,000,000,000 tons, account for 12% of world's total amount.Because the mechanical performance and the corrosion resistance of common aluminium cable are relatively poor,, be merely 3% so the annual aluminium cable of China accounts for seldom part of Chinese cable total amount.Research and development application aluminium alloy cable is realized " with aluminium for copper ", realizes that substitution of resources just seems particularly important, thus copper core cable is substituted by the aluminium core, but the poor electric conductivity of aluminium core, mechanical performance are low.
Along with the appearance of modern high-rise big groups of building, the fire-retardant and fire-resistant requirement of cable also day by day all increases.It is worth noting, add various fire retardants or compounding aid in the insulating material, also must cause electric and decline mechanical performance.
Summary of the invention
The objective of the invention is to change the problem that electric conductivity behind the aluminium cable, mechanical performance reduce into to the copper core cable that exists in the above-mentioned technology; And add various fire retardants or compounding aid in the insulating material; Cause electric and decline problem mechanical performance; Propose a kind of aluminium alloy house lead in power cable for building, make it satisfy modern building the electric property of house lead in cable, mechanical performance and the requirement of fire resistance, poisonous gas security performance under the fire condition.
The technical scheme that realizes the utility model purpose is following:
Aluminium alloy house lead in power cable for building, it comprises the cable core that at least two cores are formed, cable core is provided with oxygen barrier layer outward; Oxygen barrier layer peripheral hardware interlocking armour; The lock armo layer is provided with the low smoke and zero halogen restrictive coating outward, is provided with filling between oxygen barrier layer and the core, and core comprises conductor and the outer insulating barrier of conductor; Wherein, conductor is an aluminium alloy conductor.
Described cable core comprises three cores.
Described insulating barrier is that low-smoke halogen-free polyolefin extrudes the insulating barrier that the back cross-linking radiation forms.
The described low-smoke non-halogen flame-retardant that is filled to is filled.
Described lock armo layer is an aluminium alloy lock armo layer.
Described aluminium alloy conductor forms by the aluminium alloy molded lines is stranded, and the cross section of stranded back molded lines is trapezoidal.
The utility model has the advantages that this aluminium alloy house lead in power cable for building satisfies high electrical property, mechanical performance, fire resistance, fire safety evaluating performance and the long term life performance demands of modern architecture to the house lead in cable fully; Alternative again copper cable economizes on resources simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, aluminium alloy house lead in power cable for building, it comprises the cable core that at least two cores are formed; In this execution mode, cable core comprises three cores, and the cable core of three core compositions is provided with oxygen barrier layer 3 outward; Oxygen barrier layer 3 peripheral hardware interlocking armours 4 are provided with low smoke and zero halogen restrictive coating 5 outside the lock armo layer 4, are provided with between oxygen barrier layer 3 and the core and fill 6; Core comprises conductor 1 and the outer insulating barrier 2 of conductor, and wherein, conductor is an aluminium alloy conductor; Be twisted into conductor 1 after the high ferroaluminium of rare earth is drawn into molded lines as conductor material, select the material of low smoke halogen-free flame-retardant polyolefin, be extruded on the conductor 1 after cross-linking radiation is processed insulating barrier as insulating barrier 2; Space between core and the oxygen barrier layer 3 is filled by halogen-free low-smoke flame retardant material, and wherein, lock armo layer 4 is an aluminium alloy lock armo layer; Outermost restrictive coating 5 is to extrude low-smoke and halogen-free flame retardant polyolefin jacket, and described aluminium alloy conductor forms by the aluminium alloy molded lines is stranded, and the cross section of stranded back molded lines is trapezoidal.
