In a kind of preferred embodiments of the fireproof control cable provided at the utility model, described heat-insulating flame-retardant layer is glass layer.
In a kind of preferred embodiments of the fireproof control cable provided at the utility model, described oversheath is ceramic silicon rubber layer.
In a kind of preferred embodiments of the fireproof control cable provided at the utility model, described overcoat is the regular polygon structure of band fillet.
In sum, the fireproof control cable that the utility model provides has following beneficial effect:
It is good that many silver-plated or that tinned copper wire is stranded conductors have laser propagation effect, the feature that anti-interference is good;
Described insulating barrier is closely knit magnesium oxide layer or polytetrafluoroethylene floor.Magnesium oxide ionic crystals does not have free electron, thus good insulating, and its fusing point is 2800 degrees Celsius in addition, good heat resistance; The dielectric constant of polytetrafluoroethylene in wider frequency range and dielectric loss all very low, and puncture voltage, specific insulation and arc resistance are all higher, and thus insulating properties is fine.
Heat-resisting aluminium alloy sleeve pipe or copper sheath have the following advantages as metal sheath: one, aluminium alloy sleeve pipe or copper sheath have excellent electric conductivity and mechanical performance, can play the effect of shielding and protection to conductor wire core; Two, aluminium alloy, copper itself have high temperature resistant, that intensity is large advantage, this metal sheath is also possessed certain fire resistance; Three, aluminium alloy sleeve pipe or the seamless setting of copper sheath, make the good airproof performance of whole cable, there is not gap, effectively stops moisture to enter cable inside and the longitudinal flow along cable, ensure that the drying of insulating barrier; Four, adopt the structure of helical corrugation shape can increase the flexibility of cable, be convenient to install, transport and storage.
Ceramic silicon rubber is nonpoisonous and tasteless at normal temperatures, has good flexibility and elasticity, and it possesses the characteristic such as high-low temperature resistant, weatherable, excellent electric insulation of usual silicone rubber.The cable of oversheath is made with ceramic silicon rubber, hard ceramic-like shell can be formed when the thermal-flame ablation of 500 degrees Celsius to 800 degrees Celsius, and this shell not melting in high temperature environments, not drip, ensure that circuit is unobstructed, simultaneously do not produce poison gas, thus avoid the secondary injury that causes when breaking out of fire human body and environment.
Described overcoat is the regular polygon structure of band fillet, adopts the cable of this structure to be convenient to high-altitude erection, and more firm in the boisterous situation in outside.
