The invention relates to the technical field of photovoltaic cables, and discloses a cold-proof photovoltaic cable, which includes a cable body, a central body inside the cable body, an insulating cavity on the side of the central body, and a cable core inside the insulating cavity. The outer wall of the cavity is provided with a through-hole connection layer, and the outer wall of the through-hole connection layer is provided with a thermal insulation cavity. The thermal insulation cavity provided is conducive to setting the internal mechanism of the body, and at the same time, the four sets of cable cores in the interior are arranged. The external good effect of the thermal insulation cavity layer, through the connection layer set inside the thermal insulation cavity, is conducive to the effective communication inside the thermal insulation layer of the body, and plays a role in the setting of multiple placement cavities on it, through the set of multiple placement cavities , which is beneficial to the filling effect of the heat-absorbing material inside it, and effectively conducts heat preservation and storage through the main body material, which is convenient for the photovoltaic cable of the main body to be placed in a cold environment, and plays an effective heat preservation and cold-proof effect inside the heat preservation cavity.
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...
