Flexural property.
Preferably, the refractory insulating layer 2 uses fire-resistant isinglass belt.Fire-resistant isinglass belt have excellent resistance to elevated temperatures and
Flame resistance energy, the volatilization of harmful vapors is substantially not present when meeting naked light and burning.The wrapped fireproof mica belt outside conductor 1
Afterwards, cable core has the advantages that excellent hot-face insulation.In addition, fire-resistant isinglass belt also has good flexibility, so that cable core also has
There is soft, bending resistance characteristic.
Preferably, the filled layer 3 is made of inorganic mineral rope.The mineral matter rope of the utility model is with natural rock
Stone and mineral etc. are raw material, are melted in furnace cupola or other tank furnaces, blow by force in certain pressure, are quenched into threadiness, then make
Cheng Shengzhi matrixes.Rock wool is resistant to 1250~1400 DEG C of high temperature.The mineral matter rope of the utility model has excellent heat-insulating property.And
Itself belong to inanimate matter silicate fiber, it is incombustible.The utility model using mineral matter rope as filled layer be filled in cable core and
Between protective case, mineral matter rope has the performances such as adiabatic high temperature resistant so that cable core is in interior warm caused by transmission of electricity in filled layer
Dissipate, heat causes fire by igniting or even burning arranged on exterior protective case in prevention.
Preferably, the fire prevention 4 ceramic fireproof silicon rubber composite band material coiling of belting layer forms.Ceramic chemoprevention
Fiery fire-resistant silicon rubber composite band is to prolong pressure as base material using ceramic fireproof silicone rubber and high temperature resistance glass fiber cloth to be combined, 350
Start to be hardened under DEG C temperatures above and form the housing of ceramic-like." ceramic " hard housing can play very in case of fire
Good fire-retardant, fire resisting, fire prevention, the effect of fire insulation, reach as high as 3000 DEG C, effective guarantee circuit it is unimpeded.
Preferably, the fire lagging 5 using can porcelain nanometer silastic material be made.Fire lagging 5 uses can
Porcelain nanometer silastic material, it possesses the good fundamental characteristics of usual silicone rubber elasticity at normal temperatures, have it is nontoxic, tasteless,
High-low temperature resistant, resistance to ozone aging, weatherable, excellent electrical insulation capability, also possess common high temperature silicone rubber it is good plus
Work performance, flexible cable state can be kept in 40 degrees below zero to 200 degree above freezing or so.Attacked in flame, temperature is up to more than 300 degree
When, the sponge ceramic body of hardness can be converted to by original soft condition, produces hole after being hardened inside fireproof jointing sheath, favorably
