It is further arranged to: being filled with more alkali-free glass ropes in the conductor side in the twining package tape.
By using above-mentioned technical proposal, alkali-free glass rope can will fill on the inside of twining package tape, reduce the deformation that cable is pressurized.
Be further arranged to: the metal screen layer is formed by proof copper-wire braided.
By using above-mentioned technical proposal, metal screen layer can reduce the external magnetic field interference that cable is subject to, so that cable
Use it is more stable.
Be further arranged to: the liner layer and the outer lining are using the grid for being mixed with fire retardant and multilayered structure
Cloth.
By using above-mentioned technical proposal, grid cloth can multi-lay winding, so that the adjustable of thickness is realized, additionally by dip dyeing
Fire retardant promotes the fire protecting performance of its own.
Be further arranged to: the armor is made of Double-layer aluminum band, and aluminium strip is spliced by preforming band body.
By using above-mentioned technical proposal, aluminium strip plays protection and buffer action.
Be further arranged to: the oversheath using flame-proof polyethylene or low smoke halogen-free sheath material the structure that extrudes, it is described
Oversheath with a thickness of 2-5mm.
By using above-mentioned technical proposal, on the one hand oversheath plays a protective role to internal conductor, rises to armor
To constraint effect, while its own with insulating capacity, use is more stable and safe.
In conclusion advantageous effects of the invention are as follows:
(1) isolation is played to conductor by twining package tape, metal screen layer, fire lagging, armor and oversheath and protection is made
It is simple with, structure and stablize, bent in use process, cable it is adaptable, can be mass-produced preparation；
(2) the inorganic mineral layer in fire lagging plays main buffer action to conductor, so that effective protection is played, it is heat-insulated
It is fire-retardant, it can prevent cable from blowing；
(3) liner layer and outer lining play the role of locking inorganic mineral layer, reduce the flowing of inorganic mineral layer, it is ensured that electricity
The fire protecting performance of the whole each location point of cable is stablized, while also strengthening the stability of cable entirety.
