Abstract
The invention discloses a kind of copper core low smoke, zero halogen copper strips armoured power cable, press copper conductor including be positioned at cable bosom, extrude semiconductive shielding layer, polyethylene layer and strippable semi-conductive insulation shield layer respectively in three-layer co-extruded mode copper conductor is outer；Metal screen layer is extruded outside semi-conductive insulation shield layer, at the outer wrapped alkali-free glass fiber band of metal screen layer, outside alkali-free glass fiber band, first wrapped aluminium-plastic tape extrudes low smoke and zero halogen oxygen barrier layer again, copper strips armor is first woven again at alkali-free glass fiber band outside low smoke and zero halogen oxygen barrier layer, finally, the outermost layer at cable extrudes low smoke halogen-free flame-retardant polyolefin oversheath.The present invention has bending property, tension compressive property, fire resistance, anticorrosive property, the feature such as ageing-resistant.
Description
Technical field
The present invention relates to electric wire field, be specifically related to a kind of copper core low smoke, zero halogen copper strips armoured power cable.
Background technology
Progress and the development of society, numerous Business groups, skyscraper, place of public amusement, subway along with science and technology
And underground street etc. continues to bring out, its power consumption grows with each passing day, and kind and the consumption of all kinds of cables increase the most accordingly.But it is common
Cable can not bear mechanical external force simultaneously and carry out the most waterproof, and in many important events, once cable sustains damage or enters
Water results in the systems such as power supply, communication and cannot run when even having an accident, and makes troubles to normal social life.
Mechanically damaged in order to prevent, power cable, at outer layer armored protective layer, forms armored cable.Cable adds armour
The purpose of dress layer is in addition to strengthening the mechanical protection such as tensile strength, comprcssive strength and increasing the service life, more importantly by screen
Cover protection improve cable interference free performance, also can in case pound, press, rack cable sheath after damage core cause short circuit.Armouring
Cable is mainly used in the temperature survey of chemical industry, metallurgy, machine-building, generating and scientific experimentation etc., signal transmission and special heating,
The deficiency of existing armored cable is: armored protective layer tensile strength is relatively low, and the external force born is the biggest；Armored protective layer screen
Cover weak effect, it is impossible to for the occasion that electromagnetic interference is serious；Form it addition, cable core is that many insulated wire cores of employing are stranded, and every
Individual insulated wire cores is all the outer extruded insulation layer of conductor, and such to extrude effect bad, easily ftractures when extruding, and wastes material
Material.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is provided that one has magnetic-field strong interference immunity, bending property, resists
Draw the copper core low smoke, zero halogen copper strips armoured power cable of compressive property, fire resistance, anticorrosive property.
For achieving the above object, the present invention provides a kind of copper core low smoke, zero halogen copper strips armoured power cable, including being positioned at electricity
Cable bosom press copper conductor, extrude semiconductive shielding layer, polyethylene insulation respectively in three-layer co-extruded mode copper conductor is outer
Layer and strippable semi-conductive insulation shield layer；Metal screen layer is extruded, in metallic shield outside semi-conductive insulation shield layer
The outer wrapped alkali-free glass fiber band of layer, outside alkali-free glass fiber band, first wrapped aluminium-plastic tape extrudes low smoke and zero halogen oxygen barrier layer, again at low cigarette
First weaving copper strips armor outside Halogen oxygen barrier layer further around bag alkali-free glass fiber band, finally, the outermost layer at cable extrudes low smoke and zero halogen
Fire retardant polyolefin oversheath.
Preferably, described metal screen layer is soft copper band.
The beneficial effects of the present invention is:
Compared with prior art, the simple in construction of the present invention, use copper strips sheathed structure so that bending property, tension crushing resistance
Energy, fire resistance, anticorrosive property are greatly improved；The metal screen layer of this cable uses soft copper strip shielding so that cable is to electromagnetism
Shield effectiveness improves many times；Use double-deck alkali-free glass silk fiber band so that the fire resistance of cable is improved significantly, is
Common 2 times；Use halogen-free and low-smoke flame-retardant polyolefin oversheath, improve the resistance to ag(e)ing of cable, resistance to anti-flammability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with the present invention, it should be understood that these embodiments are merely to illustrate
The present invention rather than limit the scope of the present invention, after having read the present invention, each to the present invention of those skilled in the art
The amendment planting the equivalent form of value all falls within the application claims limited range.
As it is shown in figure 1, the present invention provides a kind of copper core low smoke, zero halogen copper strips armoured power cable, including be positioned at cable in
The heart press copper conductor 1, copper conductor outer with three-layer co-extruded mode extrude respectively semiconductive shielding layer 2, polyethylene layer 3 with
And strippable semi-conductive insulation shield layer 4；Metal screen layer 5 is extruded, at metal screen layer outside semi-conductive insulation shield layer
Outer wrapped alkali-free glass fiber band 6, outside alkali-free glass fiber band, first wrapped aluminium-plastic tape 7 extrudes low smoke and zero halogen oxygen barrier layer 8, again at low cigarette
First weave copper strips armor 9 outside Halogen oxygen barrier layer further around bag alkali-free glass fiber band 6, finally, the outermost layer at cable extrude low cigarette without
Halogen fire retardant polyolefin oversheath 10.Wherein, described metal screen layer is soft copper band.
The above is only the preferred embodiment of the present invention, it is noted that come for those of ordinary skill in the art
Saying, under the premise without departing from the principles of the invention, it is also possible to make some modification and improvement, these also should be regarded as belonging to the present invention
Protection domain.
