Electrical insulating property is good, resistance to combustion, corrosion resistance are good, preferably protects cable.
It is with natural rock and mineral etc. for raw material that the filler, which uses minerals rope, minerals rope, in furnace cupola
Or fusing in other tank furnaces, it blows by force in certain pressure, be quenched into threadiness, rope matter matrix is then made, with resistance to 1250~
1400 DEG C of high temperature, excellent heat-insulating property, and itself belong to inanimate matter silicate fiber, it is incombustible.
The steel-tape armouring uses stainless steel steel foil；The steel-tape armouring thickness is 0.3mm-1.5mm, is conducive to carry
The mechanical strength of high cable improves erosion prevention, extends the service life of cable.
The flame retardant coating uses ceramic polyolefin refractory matter, has at 650 DEG C or more of temperature or flame condition,
It can be quickly generated complete ceramic-like shell, bending strength is not cracked, is not dripped up to 10MPa, the ceramic-like shell of generation,
In addition to excellent electric isolution performance, also there is fabulous oxygen barrier heat insulation, thermal-flame can be effectively isolated to circuit
Internal infringement, delays the decomposition of internal material, conductor is avoided to fuse in flame, ensures circuit in case of fire smooth
It is logical.
Compared with prior art, the utility model has the advantages that：
