Abstract

The utility model discloses a copper core does not have steamed low cigarette copper strips armor power cable, including lieing in the copper conductor that sticiss in cable bosom, the copper conductor outside with the three -layer altogether crowded mode divide the don't push to wrap the semiconduction insulation screen that semiconductive shielding layer, polyethylene insulation and strippable leave, crowded metal encapsulated shielding layer outside semiconduction insulation screen, lapping alkali -free glass fiber tape iron shielded layer outside, the outer first lapping composite aluminium -plastic tape of alkali -free glass fiber tape again the extrude low smoke and zero halogen separate the oxygen layer, separate the outer elder generation in oxygen layer at the low smoke and zero halogen and weave copper -tape armor layer again at alkali -free glass fiber tape, at last, at the outmost extrude low smoke and zero halogen flame retardant polyolefin oversheath of cable. The utility model has the characteristics of bending property, tensile compressive property, fire behaviour, resistance to corrosion, ageing -resistant etc.

Description

A kind of copper core low smoke, zero halogen copper strips armoured power cable

Technical field

This utility model is related to electric wire field, and in particular to a kind of copper core low smoke, zero halogen copper strips armoured power cable.

Background technology

With the progress and the development of society of science and technology, numerous Business groups, skyscraper, place of public amusement, subway And underground street etc. continues to bring out, its power consumption grows with each passing day, and the kind and consumption of all kinds of cables also accordingly increase.But it is common Cable can not bear mechanical external force simultaneously and carry out effective waterproof, in many important events, once cable sustains damage or enters When water results in the systems such as power supply, communication and cannot run or even accident occurs, make troubles to normal social life.

Mechanically damaged in order to prevent, power cable forms armored cable in outer layer armored protective layer.Cable adds armour The purpose of dress layer passes through screen in addition to strengthening the mechanical protections such as tensile strength, comprcssive strength and increasing the service life, more importantly Cover protection and improve cable interference free performance, also can be in case core is damaged after pounding, press, racking cable sheath causes short circuit.Armouring Cable is mainly used in temperature survey, signal transmission and the special heating of chemical industry, metallurgy, machine-building, generating and scientific experimentation etc., The deficiency of existing armored cable is：Armored protective layer tensile strength is relatively low, and the external force born is not big enough；Armored protective layer screen Cover effect poor, it is impossible to for the serious occasion of electromagnetic interference；In addition, cable core is formed using many insulated wire cores are stranded, and it is every Individual insulated wire cores are all the outer extruded insulation layers of conductor, and such effect that extrudes is bad, easily ftractures when extruding, and wastes material Material.

Utility model content

In order to overcome the deficiencies in the prior art, there is provided a kind of to there is magnetic-field strong interference immunity, bending property, resist Draw compressive property, fire resistance, the copper core low smoke, zero halogen copper strips armoured power cable of anticorrosive property.

For achieving the above object, this utility model provides a kind of copper core low smoke, zero halogen copper strips armoured power cable, including position Press copper conductor in cable bosom, semiconductive shielding layer, polyethylene are extruded respectively in three-layer co-extruded mode copper conductor is outer Insulating barrier and strippable semi-conductive insulation shield layer；Metal screen layer is extruded outside semi-conductive insulation shield layer, in metal The outer wrapped alkali-free glass fiber band of 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 outside low smoke and zero halogen oxygen barrier layer further around bag alkali-free glass fiber band, finally, low cigarette is extruded in the outermost layer of cable Halogen-free anti-flaming polyolefin oversheath.

Preferably, described metal screen layer is soft copper band.

The beneficial effects of the utility model are：

Compared with prior art, simple structure of the present utility model, using copper strips sheathed structure so that bending property, anti- Compressive property, fire resistance, anticorrosive property is drawn to greatly improve；The metal screen layer of the cable adopts soft copper strip shielding so that electricity Cable improves many times to effectiveness；Using double-deck alkali-free glass silk fiber band so that the fire resistance of cable is obtained significantly Improve, be common 2 times；Using halogen-free and low-smoke flame-retardant polyolefin oversheath, the resistance to ag(e)ing of cable is improve, it is resistance to fire-retardant Property.

Description of the drawings

Fig. 1 is structural representation of the present utility model.

Specific embodiment

Below in conjunction with the accompanying drawings and specific embodiment, further elucidate this utility model, it should be understood that these embodiments are only used for Illustrate this utility model rather than limit scope of the present utility model, after this utility model has been read, art technology Modification of the personnel to the various equivalent form of values of the present utility model falls within the application claims limited range.

As shown in figure 1, this utility model provides a kind of copper core low smoke, zero halogen copper strips armoured power cable, including positioned at cable Copper conductor 1 is pressed in bosom, extrudes semiconductive shielding layer 2, polyethylene insulation respectively in three-layer co-extruded mode copper conductor is outer Layer 3 and strippable semi-conductive insulation shield layer 4；Metal screen layer 5 is extruded outside semi-conductive insulation shield layer, in metal screen The outer wrapped alkali-free glass fiber band 6 of layer is covered, first wrapped aluminium-plastic tape 7 extrudes low smoke and zero halogen oxygen barrier layer 8 again outside alkali-free glass fiber band, Copper strips armor 9 is first woven outside low smoke and zero halogen oxygen barrier layer further around bag alkali-free glass fiber band 6, finally, is extruded in the outermost layer of cable low Cigarette halogen-free anti-flaming polyolefin oversheath 10.Wherein, described metal screen layer is soft copper band.

The above is only preferred implementation of the present utility model, it is noted that for the ordinary skill people of this area For member, on the premise of without departing from this utility model principle, some modifications and improvement can also be made, these also should be regarded as category In protection domain of the present utility model.

Claims
