With the development of construction business, energy conservation and environmental protection and raising cable service performance have become development priority, at present In civil buildings, the service life of building is 50~70 years, but the ordinary life of normal cable is 30 years or so, but existing There is the cable in technology often to be influenced by temperature, humidity or other natural environments, causes cable to be damaged in advance, and cause Safety accident.

Traditional fire-resisting cable has following defects that

1, using single layer dielectrics, the service life of cable is short；

2, be mainly using the shortcomings that traditional Mica tape refractory material: mica intensity is low, is sintered after high temperature sintering Layer is loosely organized, and stress is easily destroyed, and has seriously affected the fire resistance of refractory material；

3, fire resistance is poor, and when burning releases a large amount of toxic and harmful gas；

4, the round conductor structure of tradition 3+2 cable, in stranding, filling gap is excessive, and cable is caused to use excessive material, It causes to waste；

5, it after restrictive coating is destroyed, can comparatively fast reduce the insulated wire cores service life.

Utility model content

The purpose of this utility model is that solve the above-mentioned problems and provides a kind of high life LSOH anti-flaming pottery Porcelain fire-resisting cable.

The utility model achieves the above object through the following technical schemes:

A kind of high life LSOH anti-flaming ceramic fire-resisting cable, including a plurality of conducting wire and it is coated on a plurality of conducting wire Outer surrounding layer, the conducting wire include copper core and the insulating layer that is coated on outside the copper core, and a plurality of conducting wire includes cutting Face shape is circular first conducting wire and cross sectional shape is non-circular second conducting wire, and the section of second conducting wire is by evagination The sideline of outer camber line, the interior camber line of indent and two sides is formed by connecting, and the insulating layer being coated on outside the copper core includes pottery Porcelain polyolefin inner insulating layer and cross-linked polyolefin external insulation layer, it is resistance to that the surrounding layer is followed successively by Ceramic silicon rubber from inside to outside Fire band wrapping layer, aluminium alloy chain armor and cross-linked polyolefin sheath entirely, in the Ceramic silicon rubber fire resistant belt wrapping layer Equipped with the glass fibre gasket for packing being placed in outside a plurality of conducting wire.

Preferably, first conducting wire be two, second conducting wire be three, the section of second conducting wire it is interior Camber line is shorter than outer camber line and two sidelines between angle be 100 °, three second conducting wires are around wherein one described first Conducting wire close-packed arrays in the Ceramic silicon rubber fire resistant belt wrapping layer, another first conducting wire be placed in two it is adjacent Between second conducting wire.

The utility model has the beneficial effects that:

High life LSOH anti-flaming ceramic fire-resisting cable described in the utility model has the advantages that

1, the double insulating layer structure constituted using ceramic polyolefin inner insulating layer and cross-linked polyolefin external insulation layer, enhancing Insulation effect, increases the service life of cable；

2, made using ceramic polyolefin inner insulating layer, glass fibre gasket for packing and Ceramic silicon rubber fire resistant belt wrapping layer Cable forms hard ceramic-like armouring shell when encountering flame combustion, can effectively stop flame combustion, and the cigarette generated The nontoxic Halogen of mist, increases the fire-resistance property of cable, and fire resistance rating can reach the A grade of GB/T19666；

3, using aluminium alloy, chain armor makes cable still can protect the construction of cable when restrictive coating is destroyed entirely Integrality guarantees conducting wire safe power supply；

4, overall structure is all made of LSOH anti-flaming material, so that cable does not discharge poisonous and harmful gas in combustion Body, and realize that cable can continued power in flame environment；

5, using the conducting wire of two kinds of cross sectional shapes, the gap between conducting wire is preferably arranged and is reduced between each conducting wire, is made Cable compact overall structure is obtained, saves filler cost, and can be according to various cross-sectional areas using three second conducting wires as three Root firewire, using two first conducting wires as zero curve and ground wire, optimize the electric conductivity of cable.
