Problems solved by technology

[0002] The power cord is a wire material commonly used in daily life. The power cord includes an outer coating layer and an inner power core wire. This structure can only resist general pressure and shearing. When sheared, the outer coating layer is damaged. Damage, the inner cable core is directly damaged by shearing, there is no buffering process, so the inner power core wire tends to have a shorter service life when used in this exposed environment, therefore, for the exposed ground, there is a risk of being sheared Extruded power cords, the safety structure of such power cords needs urgent improvement in order to increase their safety performance and service life

Embodiment Construction

[0015] Such as figure 1 and figure 2 As shown, the power transmission line includes an outer coating layer 8, and an installation cavity 4 is provided in the outer coating layer 8, and an outer protective layer 6 and a hollow layer 9 are installed in the installation cavity 4;

[0016] The cross-sections of the outer protective layer 6 and the hollow layer 9 are circular hollow structures, which are equal in length to the entire outer covering layer 8. The outer protective layer 6 and the hollow layer 9 are both closed structures, and the outer protective layer has a A closed first air storage chamber 7, and a closed second air storage chamber 2 inside the hollow layer 9;

[0017] Two ends of the first air storage cavity 7 are respectively provided with a wire outlet hole, and the power supply core wire 5 passes through the wire outlet hole and is sealed and fixed with glue;

[0018] The outer protective layer 6 is located on the top of the hollow layer 9, the power supply ...

Abstract

A power transmission line including the outer coating, A mounting cavity is provided in the outer coating layer, An out protective layer and a hollow layer are arrange in that mounting cavity, the outer protective layer and the hollow layer have circular hollow structure in cross section, which is as long as the entire outer coat, the outer protective layer and the hollow layer are both two-end closed structures, The outer protective layer is internally provided with a closed first gas storage cavity, the hollow layer is internally provided with a closed second gas storage cavity, two ends ofthe first gas storage cavity are respectively provided with an outlet hole, the power supply core wire passes through the outlet hole and is glued and sealed, the outer protective layer is located atthe top of the hollow layer, and the power supply core wire is internally arranged in the first gas storage cavity. The invention is simple in structure, has very good compression resistance, can fully protect the inner power core wire after being pressurized, prevents the power core wire from being damaged, and is mainly used for exposing on the external ground.

Description

technical field [0001] The invention relates to the field of power wires, in particular to a power transmission line. Background technique [0002] The power cord is a wire material commonly used in daily life. The power cord includes an outer coating layer and an inner power core wire. This structure can only resist general pressure and shearing. When sheared, the outer coating layer is damaged. Damage, the inner cable core is directly damaged by shearing, there is no buffering process, so the inner power core wire tends to have a shorter service life when used in this exposed environment, therefore, for the exposed ground, there is a risk of being sheared For extruded power cords, the safety structure of such power cords needs to be improved urgently in order to increase their safety performance and service life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a power transmission line, which adopts a suspende...
