Preferably, the sheath is identical as the structure of outer jacket, using the strong welding wire of intensity high-corrosion resistance It is made using preformed spiral preforming process.
Preferably, monofilament tensile strength >=100MPa of the welding wire, a diameter of 2.6mm, copper coating thickness >= 80μm。
Preferably, the center color punctuation as installation starting point, the point are also labeled on the outside of the structure sheaf of the outer jacket Using Waterproof paint brushing, width 2-3cm.
Preferably, the strand of the sheath and the outer jacket is twisted to the outer layer with its clue covered to consistent.
Preferably, the position that the sheath is in contact with the clue is also stained with for preventing armour protective layer axial Mobile conductive sand.
Preferably, the intermediate flame-retardant layer uses burning behavior class to be made of the fire proofing of A1.
Preferably, the intermediate flame-retardant layer further includes insulating layer, and the insulating layer is made of highdensity graphite paper.
Preferably, the clue can bear 4000A-7500A short-circuit current rush after whole preformed cladding.
Compared with prior art, the beneficial effects of the present invention are: building block of the present invention is quality material, integral coating 4000A-7500A short-circuit current rush can be born on to clue, armouring protects lines ectonexine hank knotting and uses intensity highly corrosion resistant The strong welding wire of energy, monofilament tensile strength >=100MPa of welding wire hit in object and clue are protected not damaged in clue Bad, the conductive sand of adherency on the inside of internal layer hank knotting can prevent preformed armouring shield lines movement, and preformed armouring shield lines centre is fire-retardant It is important leverage that layer insulating layer made of highdensity graphite paper, which is protection clue, and armouring shield lines are made of preformed, To the unstressed concentration of the uniform force of ground wire, reliable in mechanical performance, install convenient is not necessarily to tool, can effective protection clue, table Face metal structure is hit by foreign matter and will not be damaged, clue occur overlap joint short circuit when, burn be surface preformed armour Ceiling is filled, clue will not be damaged.
