Description
Technical field
The present invention relates to electric power cable technical field, relate in particular to a kind of environment friendly heat resistant tensile type intrinsic safety computer shielded cable.
Background technology
Along with society constantly advances, due to the universal utilization of computer system, particularly this system is also more and more higher to the requirement of workplace: high temperature resistant, explosion-proof, so be like this too to the requirement of cable, conventional anti-explosion cable is that conductor increases fireproof mica band structure or magnesium oxide outward, but these conventional anti-explosion cables have a fatal defect: mobile effect extreme difference, and the former cable high-temperature resistant result is poor, and contaminated environment in combustion process, silicone rubber for cable itself also has certain explosion-proof performance, the silicon dioxide that cable generates in combustion process also can play insulating effect, but the flame retardant effect of silicone rubber for cable is poor, in the time of cable fire, withdrawing naked light cable will burn away, can not automatic distinguishing.Require cable to have good shielding properties simultaneously, have good anti-external electromagnetic field and disturb and do not produce external interference, this just requires cable to have " essential safety " characteristic.
To the mobile requirement with cable too, it is also more and more higher requiring, if cable does not have good flexibility and good tensile property, affects so to a great extent the useful life of electric wire at present.At present domestic applicable mobile insulation and sheath material with cable is a lot, and most employing of tensile structure is added on the both sides of round cable or the both sides of flat cable, in the time that equipment is installed, is connected in required computer control system by strengthening tension steel wire.Because increased the tensile structure of cable, the external diameter of cable also increases a lot, has occupied computer control system space.
Summary of the invention
In order to solve the technical problem existing in background technology, the present invention proposes a kind of environment friendly heat resistant tensile type intrinsic safety computer shielded cable, it has good high-temperature stability, fire-resistance property, flame-retarding characteristic, environmental protection characteristic, softness characteristics and tensile characteristics, and the scope of application is more wide.
A kind of environment friendly heat resistant tensile type intrinsic safety computer shielded cable that the present invention proposes, comprise by four parallel vertical put and mutually circumscribed conductor form cable core, conductor is made up of three pair twist wires and the interior polyester belt lapping layer and the first screen that are coated on successively outside wire, wire is made up of core and the insulating barrier that is coated on outside core, the packing material that blocks water is inserted in space between interior polyester belt lapping layer and four conductors, polyester belt lapping layer outside cable core is coated outward successively, secondary shielding layer, wire armoring layer and external sheath layer, between the conductor group of arbitrary neighborhood and outer polyester belt lapping layer, the gasket for packing that cross section is right-angled triangle is inserted in space, and two right angle faces and the conductor group of gasket for packing are circumscribed.
Preferably, in the first screen, secondary shielding layer, be equipped with drainage thread.
Preferably, drainage thread adopts copper wire to make, and drainage thread cross section is not less than 0.3mm
2.
Preferably, the count of wire armoring layer is at 35%-45%.
Preferably, insulating barrier, external sheath layer adopt environmental-protection flame-retardant macromolecule silicon rubber insulation material, SiO in silicon rubber insulation material
2molecular weight up to more than 700,000 playing insulating effect.
The present invention adopts wire armoring layer in order to improve the tensile strength of cable, without connect tensile device in computer control system, has so also saved the space of computer control system.When electric installation, need only conductor is connected reliably just passable, more convenient to use.Wire armoring layer can also play the effect of shielding outer signals, and has advantages of the oversheath of preventing cracking, long service life.
The present invention has good high-temperature stability, fire-resistance property, flame-retarding characteristic, environmental protection characteristic, softness characteristics, tensile characteristics and shielding character; Both guarantee the compactedness of the construction of cable, improved again the block-water performance of cable, there is fabulous electric property.
