Cold-proof photovoltaic cable

Abstract

The invention relates to the technical field of photovoltaic cables, and discloses a cold-proof photovoltaic cable which comprises a cable body, wherein a center body is arranged in the cable body, an insulating cavity is formed in the side edge of the center body, a cable core is arranged on the inner side of the insulating cavity, a through hole connecting layer is arranged on the outer wall of the insulating cavity, a heat preservation cavity is formed in the outer wall of the through hole connecting layer, by arranging the heat preservation cavity, a good heat preservation cavity layer effect on four sets of cable cores arranged in the body is achieved while mechanisms in the body are arranged, through the communication layer arranged in the heat preservation cavity, the effective communication effect in a heat preservation layer of the body is achieved, and the arrangement effect on a plurality of accommodating cavities in the body is achieved; and by arranging the plurality of accommodating cavities, the filling effect on the heat absorption material body in the photovoltaic cable is facilitated, the heat preservation and storage effects are effectively achieved through the body material, the body photovoltaic cable can be conveniently placed in a cold environment, and the effective heat preservation and cold prevention effects in the heat preservation cavity are achieved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cables, in particular to a cold-proof photovoltaic cable. Background technique [0002] With the progress of our country's economy, communication technology, radio and television, railway transportation, petrochemical industry, construction and other fields are also developing rapidly. Various cables are widely used in these fields and become one of the indispensable components. The performance requirements are continuously improved with the gradual expansion of the application field. [0003] During the use of photovoltaic cables in the prior art, it is difficult to achieve effective cold and frost resistance, making it difficult for the photovoltaic cables to adapt to the effective use effect in low temperature environments, reducing their practical performance, and the photovoltaic cables in the prior art, It is difficult to achieve good internal flame-retardant protection performance, an...
