Abstract
Provided is a hollow core cable capable of dissipating heat. The hollow core capable of dissipating the heat comprises a hollow core electric conductor, an insulating layer, and two wiring terminals, wherein the insulating layer is wrapped on the outer portion of the hollow core electric conductor and the two wiring terminals are placed at two ends of the hollow core electric conductor and are fixedly connected with the hollow core electric conductor. The hollow core cable capable of dissipating the heat is characterized in that each wiring terminal is provided with a heat dissipation hole communicated with a hollow core cavity of the hollow core electric conductor. So, heat produced by the hollow core cable capable of dissipating the heat is easy to dissipate due to resistance existing in a transmission process and dirt are not easy to enter into the hollow core cable. Whether a single cable or a plurality of cables are used, leakage of electricity can be avoided. The hollow core cable capable of dissipating the heat is large in loaded current flow, low in temperature rising, practical, reliable, good in safety, capable of meeting usage need of working for long time with large quantity of electricity, and long in service life. Besides, the weight of the cable can be reduced, electric conducting material can be saved, and cost can be lowered.
Description
Technical field
The utility model relates to a kind of service cable, particularly a kind of hollow core cable that can dispel the heat.
Background technology
At present, common cable has electric conductor, is wrapped in the insulating barrier of electric conductor outside, and weight is large, and the existence owing to resistance in the transmission of electricity process produces heat, and heat is difficult for shedding, and needs to strengthen wire diameter or reduce electric current just can address this problem.In order to reduce the weight of electric conductor in the cable, people utilize electric current " kelvin effect " to design hollow core cable, for example, CN101894626A discloses a kind of hollow core cable, weave webmaster as Ampereconductors with copper, at the inside and outside insulating barrier that all covers of webmaster, the insulating barrier material is ethylene propylene diene rubber silicon rubber blend glue.On copper braiding webmaster and insulating barrier, louvre is arranged.This hollow core cable easily advances dirt, easily leaks electricity during single use, and dangerous large, easy short circuit when three-phase is used in combination can't be used.
Summary of the invention
The purpose of this utility model provides a kind of hollow core cable that can dispel the heat, and technical problem to be solved is that this hollow core cable heat in the transmission of electricity process is easily shed, practicality, and fail safe is good, long service life.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of hollow core cable that can dispel the heat, have hollow electric conductor (in other words conj.or perhaps hollow conductor layer), be wrapped in hollow electric conductor outside insulating barrier, be positioned at two binding posts that are fixedly connected with hollow electric conductor at described hollow electric conductor two ends, its technical scheme is that above-mentioned each binding post has the louvre that is connected with the hollow cavity of hollow electric conductor.
In the technique scheme, described hollow electric conductor is the tubular cylinder bodily form, the bottom of each binding post is cylindrical and stretches into the hollow electric conductor from the termination hollow position of hollow electric conductor, on the periphery of the lower cylindrical body of each binding post preferably all with several annular grooves, the wall of hollow electric conductor is recessed and clamp-on respectively in these several annular grooves at the position corresponding with described several annular grooves, the top of each binding post is cuboid round end line nose, be provided with bolt hole, each binding post has the louvre that is connected with the hollow cavity of hollow electric conductor.The diameter of louvre can be 3 millimeters.
In the technique scheme, hollow electric conductor is preferably aluminium-alloy pipe or copper pipe, the bottom of each binding post is cylindrical and stretches into the hollow electric conductor from the termination hollow position of hollow electric conductor, on the periphery of the lower cylindrical body of each binding post preferably all with several annular grooves, the wall of hollow electric conductor is recessed and clamp-on respectively in these several annular grooves at the position corresponding with described several annular grooves, the top of each binding post is cuboid round end line nose, be provided with bolt hole, each binding post has the louvre that is connected with the hollow cavity of hollow electric conductor.The diameter of louvre can be 3 millimeters.
Each binding post described in the utility model has the louvre that is connected with the hollow cavity of hollow electric conductor.Like this, easily shed owing to the existence of resistance produces heat in the transmission of electricity process, dirt can not enter this hollow core cable simultaneously, can not leak electricity when being single use or many uses, its live flow is large, and temperature rise is low, and is practical, reliable, fail safe is good, can satisfy the use needs that large electric current works long hours, long service life, and alleviated the weight of cable, save electric conducting material, reduced cost.
