Fire prevention coaxial cable insulation cable (i.e. weak-current cable belongs to communication cable class), silica also need specially for coaxial cable insulation cable of preventing fires
Foaming is carried out to silica with equipment and is processed into fumed silica, so as to reduce its dielectric constant, the coaxial electrical of making
Cable can be only achieved normal impedance.Fumed silica insulating surface is crude rough, causes the impedance of coaxial cable uneven, together
When influence transmission performance, therefore, it is pure with fumed silica insulate working frequency too high will not be usually no more than 1GHz.This reality
With a kind of new Novel fireproof coaxial cable, the cable uses compound inslation, adds one again using fumed silica insulation is outer
Layer Ceramic silicon rubber, the smooth rounding of insulating surface, makes the impedance of coaxial cable uniform, and transmission performance is stable, the utility model
Screen layer and outer conductor are PAP, and cable work frequency is high, up to 3GHz；Silica belongs to traditional and is applied to electricity
The refractory material of line cable, and Ceramic silicon rubber remaining incombustible after high-temp combustion, can condense into ceramics difficult for drop-off
Property duricrust, the cable jacket use Flame-retardant ceramic polyolefin, extend burning time；And ceramic polyolefin is through high temperature
Remaining after combustion incombustible, ceramics duricrust difficult for drop-off can be also condensed into, the heat-insulated effect of fire insulation be played, using titanium dioxide
Three kinds of silicon, Ceramic silicon rubber and Flame-retardant ceramic polyolefin refractory materials are used together, and substantially increase fire resisting of cable etc.
Level.
