Abstract
The utility model provides a ceramic silicon rubber insulating copper belt interlocking armored fireproof cable. It is characterized in that the fireproof cable includes a plurality of wire cores composed of copper conductors coated with ceramic silicon rubber insulating layers, a gird layer, a ceramic silicon rubber lining layer, and a copper belt interlocking armored sheath layer. The gird layer, the ceramic silicon rubber lining layer, and the copper belt interlocking armored sheath layer wrap the wire cores successively. A space between the wire cores and the gird layer is filled with ceramic silicon rubber filling material.
Description
Technical field
The utility model relates to a kind of fireproof cable, particularly a kind of potteryization silicon rubber insulation copper strips lock armo fireproof cable.
Background technology
Traditional fireproof cable adopts the magnesia mineral insulated cable and mostly with the fire-resisting cable of the wrapped inorganic insulation of mica tape.Though mineral insulated cable has splendid fire resistance, its manufacturing process is complicated, needs production equipment special, and production cost is high.The easy moisture absorption of simultaneous oxidation magnesium can cause cable to descend at the insulation resistance of joint.Its outer jacket is that the copper pipe insulation is the magnesia porcelain knob of sintering, and cable is stone, can't be crooked.Add it and produce and to be discontinuous formula, cable can not length production.Therefore being difficult to extensive popularizing uses.Though the fire-resisting cable production technology with the wrapped inorganic insulation of mica tape is simple, factory length is unrestricted.But it needs multilayer wrapped in process of production, is prone to defective in its overlapping the slot place, adds and burns back mica tape embrittlement, is prone to come off, and causes fire-resistant poor effect.Be difficult to ensure safe and smooth under fire condition of communication, electric power facility.
Summary of the invention
The purpose of the utility model provides a kind of potteryization silicon rubber insulation copper strips lock armo fireproof cable to existing weak point in the above-mentioned prior art just.
The fireproof cable of the utility model utilizes the insulating barrier of potteryization silicon rubber insulation material as copper conductor, and the potteryization silicone gasket adopts the oversheath of copper strips lock armo mode as cable as the filling and the lining of fireproof cable.Make it have excellent fire protecting performance, can be through the harshest in the world at present water spray and mechanical shock fire resistance test, and have extraordinary bending property, can random length production, the suitable multiple place of laying.
The pottery silicon rubber insulation copper strips lock armo fireproof cable of the utility model comprises the core of being made up of the many copper conductors that are enclosed with the potteryization silicone rubber insulation layer respectively, is wrapped in the outer belting layer of core successively, potteryization silicon rubber serves as a contrast material layer and copper strips lock armo restrictive coating (snake tubulose copper sheath); Be filled with potteryization silicon rubber filling material in the space between core and belting layer.
The utility model is nontoxic at normal temperatures, tasteless at described potteryization silicon rubber, has good flexibility and elasticity, and it possesses the high-low temperature resistant of ordinary silicon rubber, weather-proof aging, good characteristics such as electric insulation.It is under high temperature more than 500 ℃ and flame calcination, and its organic principle changes into hard ceramics shape material in the anxious short time, formed the flame interlayer with good insulation properties, and increases with calcination time, and temperature raises, and its hard degree is obvious more.Potteryization silicon rubber also has good technology extrusion performance, can on the continuous vulcanization production line of routine, produce.Slit between core and the belting layer and lining all use the potteryization silicone gasket; It is current fundamentally to have blocked oxygen; Add the copper strips lock armo sheath that this cable adopts, formation has flexible snake tubulose copper sheath, can bear radial pressure; The protection cable is avoided extraneous mechanical damage, anti-fiery calcination.Make this construction of cable more stable, bending property is good, and fire protecting performance is excellent.Its copper strips lock armo sheath is more soft than mineral insulated cable copper sheath, and in light weight.Between conductor, apply 1000V voltage, burning is 3 hours in 750～800 ℃ flame, and cable does not puncture yet and do not open circuit.Simultaneously can be through 650 ℃ of W levels, the spray test of 15min water and mechanical shock (650 ℃ of X levels, 750 ℃ of Y levels, 950 ℃ of 15min of the Z level) test of stipulating in the Britain BS6387 standard, cable neither short circuit is not opened a way yet.This cable can be requires assistance and escape is won time enough, reliable guarantee is provided.
The beneficial effect of the utility model is following:
Because the utility model adopts the pottery silicon rubber with excellent fire protecting performance as insulation and inserts; The smog that cable produced in 2 ~ 3 minutes burning initial stages is nontoxic, the Halogen smog that the organosilicon burning generates; And in fire prevention process subsequently, no longer produce smog and pernicious gas, deserve to be called environment-friendly products.Fireproof cable is in the past compared, and can reduce production costs, and is convenient to laying installation, and is safe and reliable.It had both kept high temperature resistant, the fire prevention, LSZH of traditional mineral insulated cable, characteristic such as ageing-resistant, and it is poor to have overcome its bending property again simultaneously, is prone to the moisture absorption; Joint is many, installation is inconvenient; Manufacturing equipment costliness, complex process, yield poorly, many shortcomings such as energy consumption is high, factory length is restricted.For fire-fighting, fire safety provide a kind of novel fireproof cable.
