Abstract

The utility model discloses a flame-retardant control cable, which comprises a cable core and a filling layer, an aluminum and plastic composite band, a drainage wire, a gluing cloth band, a high-temperature plastic band, a shielding layer, an inner protection layer, an armor layer and an outer protection layer which are sequentially arranged outside the cable core. A manufacturing method for the flame-retardant control cable comprises the following steps of: wrapping a flame-retardant mica layer on a conductor; wrapping an isolation layer on the flame-retardant mica layer; extruding an insulation layer on the isolation layer, and performing steam vulcanization to obtain wire cores; twisting a plurality of wire cores to form a cable, and filling flame-retardant glass fiber ropes among cabled wire cores; wrapping a layer of aluminum and plastic composite band, the high-flame-retardant gluing cloth band and the high-temperature plastic band outside the cable core; arranging the drainage wire on the surface of the aluminum and plastic composite band; forming the shielding layer by weaving copper wires or copper bands; extruding the halogen-free low-smoke inner protection layer outside the shielding layer; armoring a steel band outside the inner protection layer; and extruding a silica gel sheath outside armored inner protection layer.

Description

A kind of fire-retardant control cable
Technical field
The utility model relates to the electric wire field, specifically is that a kind of fire-retardant control cable of low smoke and zero halogen reaches to the preparation method.
Background technology
Along with information technology application more and more widely, the integrality of cable is for can both the normal transmission signal being very important under various adverse circumstances.Spread out of and the reception process of information make signal disturb easily, and shadow plays the disorder of information, make equipment produce misoperation.In addition, when breaking out of fire, owing to contain many harmful elements, when burning, can discharge a large amount of smog and acid gas in some cable materials, this not only pollutes environment, also jeopardizes personnel's life security.
The utility model content
The utility model technical problem to be solved provides a kind of operating temperature range big, fire-resistant, good corrosion resistance, control cable of overcurrent proof magnetic disturbance and preparation method thereof.
The described a kind of fire-retardant control cable of the utility model, it comprises cable core and is successively set on cable core outer packed layer, aluminium-plastic tape, drainage thread, gluing strap, high temperature moulds band, screen, sheath, armour and outer jacket.
Said cable core forms by some cores are stranded, and said core comprises middle conductor and is successively set on conductor outer mica tape, separator and insulating barrier.
Said conductor is strands flexible conductor or single conductor.
The material of said insulating barrier is 125 ℃ of halogen-free flameproof glue stuff compoundings.Armour is a steel-tape armouring, and screen is the copper wire screen, and outer jacket is the flame-proof silicon rubber restrictive coating.
The beneficial effect of the utility model: cable conductor is surrounded with mica tape and separator outward; Insulating barrier uses 125 ℃ of halogen-free flameproof glue stuff compoundings with property; Make cable have high temperature resistant (125 ℃ working temperatures), oil resistant, low temperature resistant characteristics such as (55 ℃); Be filled with flame-retardant gasket for packing and add high flame retardant gummed cloth band and high temperature plastics band stranding with the layer of aluminum plastic composite strip between the stranding insulated wire cores, plastic-aluminum combined interband has a drainage thread to be close to plastic-aluminum combined belt surface, thisly plastic-aluminum combinedly brings perfect relatively closed magnetic field that cable provides for improving indexs such as cable attenuation performance, return loss; Drainage thread is exactly for the timely carrying-off of electric charge; Avoid electric charge accumulation causing electric field to concentrate, and then with copper wire (copper strips) shielding, its effect is to prevent electromagnetic interference.A lot of local, the control cable of computer system particularly, the screen here is used for shielding alien influence because itself electric current very a little less than, be afraid of very much extraneous electromagnetic field effects.Inner sheath is the low smoke and zero halogen plastics, and at wrapped steel-tape armouring layer, skin is a silicone rubber jacket.Silicone rubber jacket has waterproof, anti-salt fog, characteristics such as anticorrosion oil resistant; Be exactly breaking out of fire, cable can not produce a large amount of dense smoke yet, particularly in cable, has added flame retardant coating; Make cable possess fire-resistant function, can be under 800 ℃ of high temperature normal power supply one hour, so just having guaranteed has the time that takes urgent measure when breaking out of fire; Reduce fire damage, and improved the security of operation of cable and various device greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing.
With reference to Fig. 1; The control cable center of the utility model is a cable; Cable core forms by some cores are stranded; The inside of core is conductor 1, on conductor, is surrounded with fire-resistant isinglass belt 2 and separator 3, and the elastomeric compound that on separator, extrudes one deck LSOH anti-flaming is done insulating barrier 4 and it is carried out steam vulcanization (cure).With the core stranding, be filled with the combustion-proof glass fiber rope between the core and do filling 5 again, have band tightly to prick then; The metallized aluminum plastic composite strip 6 again, in aluminium-plastic tape 6 the insides the drainage thread of being close to the plastic-aluminum surface 7 arranged, and its material is that zinc-plated stranded copper wire constitutes; Be surrounded with high flame retardant gluing straps 8 outside the aluminium-plastic tape 6, mould with high temperature and be with 9 tightly to be bundled into cable formation cable core, outside cable core, have copper wire or copper strips screen 10 outside screen, to be extruded with low smoke and zero halogen sheath 11 then steel-tape armouring layer 12 is arranged outside sheath; Be used to increase the tension of cable, mechanical performances such as resistance to compression, outermost layer has silicon rubber outer jacket 13; It has the oil resistant waterproof, anti-salt fog, characteristics such as anticorrosion.
The utility model provides a kind of thinking and implementation method of control cable; Concrete application approach is a lot, for those skilled in the art, under the principle that does not break away from the utility model; Can also make some improvement, these improve the protection range that also should be regarded as the utility model.
