Abstract
The utility model relates to a halogen-free, low-smoke and irradiation cross-linking control cable, which comprises multi-strand of stranded conductors, a halogen-free, low-smoke and irradiation cross-linking polyolefin insulating layer, a talc-powder coating layer and a halogen-free, low-smoke and irradiation cross-linking polyolefin sheath, wherein the halogen-free, low-smoke and irradiation cross-linking polyolefin insulating layer is arranged outside the stranded conductors, the talc-powder coating layer is arranged outside the halogen-free, low-smoke and irradiation cross-linking polyolefin insulating layer, and an outermost layer is the halogen-free, low-smoke and irradiation cross-linking polyolefin sheath. Halogen-free, low-smoke, and irradiation cross-linking polyolefin is used by the utility model as an insulating layer and a sheath of the utility model. One layer of talc powder is coated in the process of cabling to cause the outside diameter of the utility model to be lowered, and the compact performance of a cable structure is enhanced, and the utility model is especially suitable for mechanization head peeling and terminal smashing.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of outside diameter of cable that makes and reduces greatly, improves the compactedness of the construction of cable greatly, the low smoke, zero halogen irradiation cross-linked control cable that is fit to very much mechanization stripping head and pounds terminal.
Background technology
Control cable is as the connecting line between each electric appliances, instrument and the automatics, is mainly used in control, the chain loop of monitoring and protection circuit etc., plays various effects such as transmitting control, is widely used in important economic departments such as various industrial and mining enterprises, communications and transportation.In enterprises such as power plant, transformer station, power circuit and petrochemical industry, just adopted a large amount of control cable, for the running of safe power supply and production system, its function even the power cable of using above backbone.Now the control cable of Sheng Chaning mainly uses polyvinyl chloride as insulating barrier and sheath, and its shortcoming is that signal attenuation is big, leaded and halogen discharges a large amount of smog and toxic gas during burning, cable conductor uses working temperature the highest 105 ℃ for a long time, the electrical property of polyvinyl chloride is relatively poor simultaneously, breakdown strength is lower, is not suitable for thinwalled insulation, in addition, in order to make cable keep circularity, be provided with the non-hygroscopic filler again in cable, cause complex structure, the outside diameter of cable of producing is bigger.
The utility model content
Technical problem underlying to be solved in the utility model is, overcome the defective that existing crosslinked control cable exists, and provide a kind of low smoke, zero halogen irradiation cross-linked control cable, it can reduce the decay of cable transmission signal, improve the cable temperature resistant grade, reduce the thickness of cable insulation, the external diameter of cable and deadweight are reduced, the filler of cancellation prior art makes the structure of cable tightr.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of low smoke, zero halogen irradiation cross-linked control cable, it is characterized in that, comprise strands conductor, low smoke, zero halogen cross-linking radiation polyolefin insulation layer, talcum powder coating and low smoke, zero halogen cross-linking radiation polyolefin jacket, this strands conductor peripheral hardware has low smoke, zero halogen cross-linking radiation polyolefin insulation layer, this insulating barrier is provided with the talcum powder coating outward, and outermost layer is a low smoke, zero halogen cross-linking radiation polyolefin jacket.
Along with the progress of science and technology, the performance of halogen-free and low-smoke flame-retardant polyolefin material is more stable, and its fire resistance has reached the requirement of cable-flame retardant, and its electrical property also is higher than polyvinyl chloride, and it is through after the cross-linking radiation, and its temperature resistant grade can be up to 125 ℃; In addition, outside polyethylene hydrocarbon insulating barrier, be provided with the talcum powder coating, can make insulation and sheath adhesion.
The utility model uses insulating barrier and the sheath of low smoke, zero halogen cross-linking radiation polyolefin as cable, and coating one deck talcum powder reduces the outside diameter of cable greatly in the stranding process, improves the compactedness of the construction of cable greatly, is fit to very much mechanization stripping head and pounds terminal.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation
The number in the figure explanation:
1 strands conductor, 2 low smoke, zero halogen cross-linking radiation polyolefin insulation layer
3 talcum powder coatings, 4 low smoke, zero halogen cross-linking radiation polyolefin jackets
Embodiment
Consult shown in Figure 1ly, the cable of the utility model embodiment adopts two 1.5mm
2Strands conductor 1, outside this strands conductor 1 is low smoke, zero halogen cross-linking radiation polyolefin insulation layer 2, outermost layer is a low smoke, zero halogen cross-linking radiation polyolefin jacket 4, adopt talcum powder coating 3 outside this insulating barrier 2 and between in the sheath 4, its finished product external diameter is 5.6mm, weight is 52kg/km, the ampacity 25A of power line.
The utility model halogen-free and low-smoke flame-retardant polyolefin material is a kind of new material with environmental protection and flame retardant efficiency, through after the cross-linking radiation, its temperature resistant grade is brought up to 125 ℃ from original 70 ℃, on the one hand the anti-environment capacity of cable is improved greatly, also improved ampacity on the other hand with a kind of sectional area cable, the third aspect has reduced the external diameter and the weight of cable, and the need of cable are reduced with the space, can improve the utilance of control cubicle or the volume of reduction control cubicle.Adopt the talcum powder coating, and omit the non-hygroscopic filler of prior art, make the structure of cable compact more, help keep cable circularity, and the first-class process operation of quick stripping of suitable mechanization.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
In sum, the utility model is on structural design, use practicality and cost benefit, it is required to meet industry development fully, and the structure that is disclosed also is to have unprecedented innovation structure, have novelty, creativeness, practicality, the regulation that meets relevant novel patent requirement is so mention application in accordance with the law.
