Description
Technical Field
The utility model relates to a light weight type cable technical field especially relates to a high strength minor diameter light weight type cable.
Background
A cable, which is a conductor made of one or more mutually insulated conductors and an outer protective insulating covering, transmits power or information from one location to another. The cables that are now commonly used are rope-like cables made by stranding several or several groups of conductors, each group being insulated from the other and often twisted around a center, the entire outer surface being covered with a highly insulating covering.
The problem that power transmission to remote mountainous areas needs to be solved by the current society is that remote mountainous area lines are difficult to erect, the traditional cables are large in weight, the bearing capacity of telegraph poles erected in the mountainous areas is not enough, a plurality of cables cannot be arranged at the same time, and the use of users is not facilitated, so that a high-strength small-diameter light-weight cable is designed.
Disclosure of Invention
The utility model discloses the technical problem that will solve is: the cable that erects in the mountain area requires highly, and traditional cable quality is great, and the wire pole bearing capacity of remote mountain area is not enough, can't support too much cable.
In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a high strength minor diameter light weight type cable, includes outer inoxidizing coating, the inside insulating layer that is provided with of outer inoxidizing coating, the inside cable core that is provided with of insulating layer, the cable core outer wall is provided with interior boundary belt.
Preferably, a plurality of grooves are formed in the inner side wall of the insulating layer, the depth of each groove is not more than one third of the width of the insulating layer, the overall weight of the cable is reduced on the premise that the structural strength of the cable is guaranteed, materials are saved, and the cost is reduced.
Preferably, the cable core is provided with a plurality ofly, the cable core is the copper product, compares in the cable core of aluminum alloy material, because the cable erection receives the region restriction great in the mountain area, and the place of buckling is more, and the difficult fracture of bending repeatedly of copper core, elasticity is better, and life is longer.
Preferably, the thickness of outer inoxidizing coating is no longer than two millimeters, and outer inoxidizing coating adopts the rubber material, and the cable is comparatively environmental protection, and fire prevention, antistatic performance are stronger.
Preferably, interior boundary belt is the heliciform setting, compares with current cable nylon layer, and this design adopts spiral belt structure, and the structure is comparatively loose, greatly reduced the holistic weight of cable, be convenient for better erect on mountain area electric wire frame. The outer side wall of the inner protective belt is tightly attached to the insulating layer, the inner side wall of the inner protective belt is tightly attached to the outer side wall of the cable core, and the cable core is conveniently wrapped inside the cable.
Preferably, the interior boundary belt is the nylon material, and ductility is better, when being convenient for protect the cable core, has improved the structural flexibility of cable, and the whole cable of being convenient for is buckled, is difficult to the rupture. The bandwidth of the inner guard band is not more than one millimeter.
The utility model has the advantages as follows:
1. the utility model discloses be provided with the recess, through set up the degree of depth on the insulating layer and be no longer than the one-third recess of insulating layer bed thickness, under the prerequisite of guaranteeing cable overall structure intensity, alleviateed the weight of cable greatly, be convenient for better erect in the mountain area.
2. The utility model discloses be provided with interior boundary belt, compare with prior art, abandoned traditional interior nylon protective layer, adopt spiral helicine nylon boundary belt, improved the flexibility of cable greatly, be convenient for buckle the cable, difficult rupture, more adapt to erectting in the mountain area, be convenient for better use.
