Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model crosslinked polyetylene insulated low-smoke non-halogen flame-retardant control cables peculiar to vessel.
Wherein: 1-conductor; 2-insulating barrier; 3-gasket for packing; 4-inhibiting tape; 5-restrictive coating.
Embodiment
Below in conjunction with embodiment, the utility model is further illustrated:
Present embodiment discloses a kind of peculiar to vessel crosslinked polyetylene insulated low-smoke non-halogen flame-retardant control cables with functions such as antiultraviolet, protection against rodents, anti-ants, its concrete structure as shown in Figure 1, comprises cable core and restrictive coating.Described cable core is by many insulated wire cores twisted synthesizing cables.Insulated wire cores is twisted into cable core, and outermost strand is to being dextrad.Its stranded pitch diameter multiple proportions: outermost layer should be not more than 18 times, and secondary skin should be not more than 25 times, outer two layers should be not more than 30 times, and outer three layers should be not more than 35 times.Described insulated wire cores is made up of conductor 1 and the insulating barrier 2 be extruded in outside conductor, conductor 1 described in the present embodiment is the rate of stretching >=25% annealing tinned copper wire, drawn by oxygen-free copper and form, described conductive surface bright and clean, that insulate without greasy dirt, not damaged burr, sharp edge and single line that is protruding or fracture.Described insulating barrier 2 is the organosilane crosslinked polyethylene insulation bed of material.
Tradition adopts the cable Long-term service temperature of PVC polyvinyl chloride layer to only have about 70 DEG C, and adopts the long-term permission working temperature of cross-linked polyethylene insulated cable can reach 90 DEG C.To keep elastic stage at 130 DEG C of temperature, relatively with prismatic PVC polyvinyl chloride cable, its combined closure system can improve about 25%.Crosslinked polyetylene insulated density is 0.92g/cm
3.And polyvinyl chloride insulation density is 1.38g/cm
3.Because XLPE insulate combination property than PVC insulation by force, allow crosslinked polyetylene insulated thickness thinner than the thickness of polyvinyl chloride insulation by national standard, therefore, cross-linked polyethylene insulated cable is more lightweight than polyvinyl chloride cable, diameter is little, mounting and installation is convenient, and attachment tab is simple, and is used widely.
Just because cross-linked polyethylene insulated cable has the incomparable advantage of PVC insulated cable.Simple, lightweight, heat-resisting good, the excellent specific property such as load capacity is strong, non-fusible, resistance to chemical attack, and mechanical strength is high of its structure, more and more comes to be admitted widely by user.After cross-linked polyethylene insulating material described in the present embodiment passes through grafting in an extruder, carry out warm water crosslinking, the degree of cross linking reaches 80-90%, and wherein warm water water temperature is 80-90 DEG C, and crosslinking time is 5-6 hour.
Gap between insulated wire cores is filled with inflaming retarding high-temperature gasket for packing 3, be surrounded with halogen-free flameproof band 4 outside cable core, inhibiting tape 4 selects bittern-free flame-proof material, greatly can improve the fire resistance of cable, when cable fire, the concentration of smog and the effusion of pernicious gas can be reduced.
One deck restrictive coating 5 is extruded with outside halogen-free flameproof band 4, restrictive coating 5 adopts low-smoke and halogen-free flame retardant polyolefin jacket material, the CAB-6058RTC that ripple CABLE MATERIALS as triumphant in Shanghai is produced, this low-smoke and halogen-free flame retardant polyolefin jacket material has the feature of low smoke and zero halogen, antiultraviolet, protection against rodents and anti-ant, its soft pliable of this restrictive coating is bent, mounting and installation is convenient, and water resistance is good.Restrictive coating 5 should easily be peeled off and not damage sheath.Jacket surface should bright and clean, uniform color.Add by the termite-resistant rodent-resistant repellant of plant extract in described restrictive coating; make the coat layer of power cable 5 containing a kind of pungent peculiar smell of storage; when mouse, ant class animal contact cable; its olfactory nerves is made to be upset and to detest and reject contact; its electric wire is dodged automatically, plays the object of protection against rodents, anti-ant, protection cable.Be added with ultra-violet absorber in low-smoke halogen-free polyolefin protective cover material, make polyolefin sheath have excellent weathering capabilities.
The peculiar to vessel crosslinked polyetylene insulated low-smoke non-halogen flame-retardant control cables primary structure that the present embodiment obtains and performance meet IEC60092-350, IEC60092-376 and specify, and respectively by the test of IEC61034, IEC60754.
The utility model is not limited to the peculiar to vessel crosslinked polyetylene insulated low-smoke non-halogen flame-retardant control cables described in above-described embodiment, and the change of the wherein change of insulated wire cores quantity, conductive material, the change of restrictive coating material are all within protection range of the present utility model.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
