The beneficial effects of the present invention is:
The present invention is by interior fire prevention clad outer cladding ceramic silicone insulation layer, under unexpected fire condition,
Ceramic silica gel energy quick solidification becomes earthenware, and effectively protection interior fire prevention clad and copper conductor be not by fire
Impact, it is ensured that the normal work of cable safety；In the range of being 0.3-0.8mm by the most loose clearance gap of increase
The chain armor of rustless steel, can significantly improve fire-protection rating, and can ensure that the existing good bending of Integral cable
Performance and heat radiation specially good effect, facilitate again wiring and lay；By increasing glass fibre belt protective layer, play buffer action,
Prevent the external force damages such as the stainless steel protection pipe abrasion to mineral insulation protective layer of outer layer, cutting；Middle fire prevention
The synthesis fluorophlogopite belt that clad uses and do not contains water of crystallization, fusing point is 1375 DEG C, margin of safety is big, resistance to height
Warm nature preferably can play and suppress because of the effect of fire spreading during unexpected fire；Copper conductor uses two class multicores to move back
The stranded soft copper conductor of fire, can make heterogeneous magnetic field cancellation reduce the effect of loss；Outer fire prevention clad uses spoke
According to crosslinking composite fire-proof compound-material oversheath, there is strong change in its molecular structure after irradiation, it is moulded
Property structural change becomes closely knit network structure, and density and structural strength are strengthened to some extent, to entirety
Cable plays comprehensive protective effect.
To sum up, this flexible compound mineral high-insulativity fireproof cable is the combustion experiment through overdoing and toxicity detection
The preferred fireproof cable that experiment etc. is tested repeatedly, through public security fire-fighting authoritative institution of China detection demonstration, globality
Can and fire resistance rating reach GA306.1-2001 standard fire-fighting requirements, it is adaptable at modern intelligence Modern Residential and
Important power transmission task is served as in densely populated place pooling zone, and raw material resources enriches, cheap,
It is easy to large-scale production and popularizes.
