Detailed Description
The present invention will be further described with reference to the following examples. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural view of a corrosion-resistant cable 100 for a railway according to the present invention. The corrosion-resistant cable 100 for railways includes an outer insulating layer 110, a corrosion-resistant layer 120, a waterproof layer 130, an inner insulating layer 140, a shielding layer 150 and a conductor body 160 in sequence from outside to inside.
Specifically, the outer insulation layer 110 employs a metal protective layer or a hard plastic layer, and the metal protective layer may use, but is not limited to, a metal copper protective layer or other corrosion-resistant metal or corrosion-resistant plastic product. Corrosion-resistant layer 120 is the copper mesh layer, and corrosion-resistant layer 120 both plays the effect of protection inner conductor body 160, plays the supporting role again, still further designs into network structure in order to reduce the weight of whole cable 100, and network structure can also realize the inside certain permeability of cable 100.
Further, in some preferred embodiments, the thickness of the outer insulating layer 110 is equal to the thickness of the corrosion-resistant layer 120, so that the corrosion-resistant performance of the cable 100 can be ensured on the basis of reducing the weight of the cable 100 and the transportation cost during the transportation and handling of the cable 100.
The inner insulating layer 140 is filled with hollow glass beads 141, and the hollow glass beads 141 are supported by the corrosion-resistant layer 120 and the shielding layer 150; wherein, hollow glass bead 141's diameter is 50 ~ 60um, and hollow glass bead 141 is the individual layer and fills, and the individual layer is filled and both has guaranteed whole cable 100's intensity, can leave relatively great space again, guarantees the inside permeability of cable 100 to obtain better corrosion resistance effect.
Further, the thickness of the outer insulation layer 110 is greater than that of the inner insulation layer 140. The outer insulating layer 110 produces a stronger protective layer for the hollow glass microspheres 141 within the inner insulating layer 140.
The waterproof layer 130 is a polyurethane waterproof layer having a vent hole. The polyurethane is not suitable for exposure, under the condition of exposure, ultraviolet rays and long-term exposure high temperature can cause the polyurethane to be modified, the aging speed is accelerated by times, a series of problems such as hardening, embrittlement, falling-off and the like can be caused most commonly when the polyurethane is used as the waterproof layer 130 basically, the polyurethane belongs to a flexible material, and when the polyurethane is used for invisible waterproofing, the ductility of the polyurethane is particularly good, the aging speed is very slow, and the polyurethane can last for twenty-few years. But once exposed, especially in the summer, it is essentially two years old. Therefore, the polyurethane waterproof layer 130 is disposed inside the cable 100, and the waterproof layer 130 is provided with a vent hole to further ensure the permeability inside the cable 100.
The barrier layer 150 is high density polyethylene. The high-density polyethylene has good heat resistance and cold resistance, good chemical stability, higher rigidity and toughness and good mechanical strength. The dielectric property and the environmental stress cracking resistance are also better. The hardness, tensile strength and creep property are better than those of low-density polyethylene; the wear resistance, the electrical insulation, the toughness and the cold resistance are all good; the chemical stability is good, and the paint is not dissolved in any organic solvent at room temperature, and is resistant to corrosion of acid, alkali and various salts; the film has low permeability to water vapor and air and low water absorption. The high density polyethylene shielding layer 150 cooperates with the polyurethane waterproof layer 130 of the vent hole to discharge water vapor, thereby preventing water from affecting the performance of the conductor body 160.
The utility model provides a corrosion-resistant cable 100 is used to railway, through the combination of means such as polyurethane waterproof layer 130 that adopts copper network layer, inner insulating layer 140 individual layer to fill hollow glass microballon 141, waterproof layer 130 for having the air vent on corrosion-resistant layer 120 to improve this corrosion-resistant cable 100 performance is used to railway.
Furthermore, the strength of the cable 100 is improved by means of hollow glass beads 141, a metal layer or a hard plastic layer, a steel mesh and the like, so that the cable is better applied to complex environments such as railways and the like.
