Description

A kind of fire-resisting cable

Technical field

The utility model relates to field of cable technology, and in particular to fire-resisting cable.

Background technique

Currently, the fire-retardant problem of wire and cable gradually causes everybody attention with the frequent generation of electrical fire accident, According to data introduction, in the fire that China occurs, because of fire half caused by electrically or so, due to cable aging in electrical fire Larger proportion is accounted for using caused fire with overload.Therefore it is proposed that a kind of fire-resisting cable.

Utility model content

(1) technical problems to be solved

In order to overcome the shortage of prior art, it is proposed that fire-resisting cable can effectively protect cable conductor, keep away Exempt to cause cable on fire because of high temperature, cause damages.

(2) technical solution

The utility model is achieved through the following technical solutions: the utility model proposes fire-resisting cables, including annular setting Multiple cable cores, conductor is equipped in multiple cable cores, the outer wall of the conductor is equipped with insulating layer, and the insulating layer is separate The outer wall of conductor is equipped with fireproof glass layer, and the fireproof glass layer is equipped with high temperature resistant band, institute far from the outer wall of insulating layer It states high temperature resistant band and is equipped with fire resisting sheath far from the outer wall of fireproof glass layer, the fire resisting sheath is far from the outer of high temperature resistant band Wall is equipped with metal outer jacket.

Further, the insulating layer is made using cross-linking polyethylene materials.

Further, the fireproof glass layer is glass fiber tape.

Further, the high temperature resistant band is glass fibre belt.

Further, the fire resisting sheath uses high flame resistance, low smoke halogen-free polyolefin.

Further, the metal outer jacket carries out using copper strips longitudinal wrap and along longitudinal direction seam weld.

Further, the conductor uses copper conductor.

(3) beneficial effect

The utility model compared with the existing technology, has the advantages that

1) for conductor using copper conductor with stronger electric conductivity, insulating layer, which is arranged, on the outside of conductor makes conductor in reality first Have insulating capacity stronger in the electricity transmission process of border, fireproof glass layer has high temperature resistant, thermal insulation separation using the setting of glass fiber tape The features such as hot；

2) high temperature resistant band can make cable core not loose, and the fire resisting sheath is effective using high flame resistance, low smoke halogen-free polyolefin Ground improves product fire-protection rating and anti-electromagnetic interference capability, and metal outer jacket can effectively carry out external high temperature fire-retardant. The utility model can effectively protect cable conductor, avoid causing cable on fire because of high temperature, cause damages.

Detailed description of the invention

Fig. 1 is the utility model overall structure diagram.

1, conductor 2, insulating layer 3, fireproof glass layer 4, high temperature resistant band 5,6 metal outer jacket of fire resisting sheath.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

Fire-resisting cable as shown in Figure 1 is equipped with conductor 1, conductor in multiple cable cores including multiple cable cores that annular is arranged 1 outer wall is equipped with insulating layer 2, and insulating layer 2 is equipped with fireproof glass layer 3 far from the outer wall of conductor 1, and fireproof glass layer 3 is separate The outer wall of insulating layer 2 is equipped with high temperature resistant band 4, and high temperature resistant band 4 is equipped with fire resisting sheath far from the outer wall of fireproof glass layer 3 5, fire resisting sheath 5 is equipped with metal outer jacket 6 far from the outer wall of high temperature resistant band 4.

Wherein, insulating layer 2 is made using cross-linking polyethylene materials, improves temperature resistant grade, and fireproof glass layer 3 is glass Glass fiber band has the characteristics that high temperature resistant, insulation, and high temperature resistant band 4 is glass fibre belt, cable core can be made not loose, fire resisting Sheath 5 uses high flame resistance, low smoke halogen-free polyolefin, effectively improves product fire-protection rating and anti-electromagnetic interference capability, outside metal Sheath 6 is using copper strips longitudinal wrap and carries out seam weld along longitudinal direction, easy for installation, and conductor 1 uses copper conductor, and conductive capability is strong.

The fire-resisting cable that the utility model is mentioned, first conductor 1 have stronger electric conductivity using copper conductor, in conductor Outside setting insulating layer 2 makes conductor have insulating capacity stronger in practical electricity transmission process, and fireproof glass layer 3 uses glass fibre The setting of band has the characteristics that high temperature resistant, insulation, and high temperature resistant band 4 can make cable core not loose, and the fire resisting sheath 5 is adopted Product fire-protection rating and anti-electromagnetic interference capability are effectively improved with high flame resistance, low smoke halogen-free polyolefin, metal outer jacket 6 can External high temperature is carried out with effectively fire-retardant.

Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this Novel conception and scope is defined.Without departing from the design concept of the present utility model, ordinary people in the field couple The all variations and modifications that the technical solution of the utility model is made, should fall within the protection scope of the present utility model, this reality With novel claimed technology contents, it is all described in the claims.
