The utility model is further described below in conjunction with accompanying drawing：
The utility model provides a kind of low smoke and zero halogen grid line 100, and as shown in Figures 1 and 2, it is from inside to outside successively
For fixed cover 200, enhancement layer 300, lapping layer 400, flame retardant coating 500 and restrictive coating 600.
Fig. 2 is refer to, the cross section of fixed cover 200 is annular, and filler is filled with the through hole 210 of fixed cover 200
220, it is preferred that filler 220 is low smoke and zero halogen glass fiber rope, not only acts as the effect of filling fixed cover 200, while can also be played
Fire-retardant effect, but because its without halogen even in burning when will not also produce thick smoke.
Four fixing pipes 230 are embedded with fixed cover 200, are set in preferable four fixing pipes 230 concyclic week, i.e., 4 solid
The center line of fixed tube 230 is generally aligned in the same plane, in order to makes whole cable uniform force during construction etc..
The inwall of fixing pipe 230 is provided with multiple semicircle fixed parts 231, it is preferred that and semicircle fixed part 231 is 4,
Annular spread is in the inwall of fixing pipe 230.Cable core 240, cable core 240 and multiple semicircles are provided with each fixing pipe 230
Fixed part 231 is circumscribed.Purpose is in order to which when cable core 240 is arranged in fixing pipe 230, fixing pipe 230 is semicircle fixed by 4
Portion can be good at that cable core 240 is fixed, while fixing pipe 230 is embedded in fixed cover 200, pass through fixed cover 200
The displacement of fixing pipe 230 can be prevented, therefore can be very good by above-mentioned setting to fix cable core 240, while each cable can be made
The Stability Analysis of Structures of core 240, its every electricity will not be caused because the distortion in construction, stretching etc. cause cable core 240 to be shifted over
The change of gas performance, make the low smoke and zero halogen grid line 100 that there is preferable electric property.
Cable core 240 includes more conductors 241 and the insulating barrier 242 being wrapped in outside more conductors 241, and insulating barrier 242 is low
The crosslinked polyetylene insulated layer of cigarette Halogen, i.e. insulating barrier 242 are made up of low smoke and zero halogen cross-linking polyethylene materials, improve whole cable

The electric property of the whole cable of increase.
Preferably, fixed cover 200 is low smoke and zero halogen crosslinked polyethylene fixed cover, i.e. fixed cover 200 is crosslinked by low smoke and zero halogen
Polyethylene support, fixing pipe 230 are low smoke and zero halogen crosslinked polyethylene fixing pipe, i.e. fixing pipe 230 is crosslinked poly- second by low smoke and zero halogen
Alkene is made.Fixed cover 200 and fixing pipe 230 are prepared using low smoke and zero halogen crosslinked polyethylene, improve whole cable high temperature resistant,
Flame resistant energy, cable will not burn during burning fire, will not produce pernicious gas, ensure that the safety in related place；Simultaneously
Also make whole cable that there is certain flexibility.
Enhancement layer 300 is also set up between fixed cover 200 and lapping layer 400, in order to further fix cable core
240, strengthen the pulling force of cable.Enhancement layer 300 is multiple FRP (Fiberglass-Reinforced Plastics) reinforcer structure
Into FRP is fiberglass reinforced plastics, typically does base with glass fiber reinforcement unsaturated polyester, epoxy resin and phenolic resin
Body, is made the reinforced plastics of reinforcing material with glass fibre or its product, can bear tension, can bear to bend again, compress and
Shear stress, it is necessary to explanation be FRP reinforcers cross section for circle, can also be other shapes, its size and quantity can
It is adjusted according to practical application.
Enhancement layer 300 is wrapped with one layer of lapping layer 400, in order to fastens FRP reinforcers, improves the property of cable
Energy.Preferably, lapping layer 400 is low-smoke non-halogen flame-retardant band lapping layer, i.e. lapping layer 400 is low-smoke non-halogen flame-retardant band, is improved whole
The fire resistance of individual cable.
Flame retardant coating 500 and restrictive coating 600 are followed successively by outside lapping layer 400.The purpose of flame retardant coating 500 is to further improve
The fire resistance of whole cable, it is preferred that flame retardant coating 500 is mica tape.Restrictive coating 600 is low-smoke and halogen-free flame retardant polyolefin jacket
Layer, i.e., restrictive coating 600 is made up of low smoke halogen-free flame-retardant polyolefin, further increases high temperature resistant, the flame resistant of whole cable
Can, cable will not burn during burning fire, will not produce pernicious gas, ensure that the safety in related place.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
Within, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
