Abstract

The invention provides a high flexible cable for a photovoltaic system. The composition or composition modes of each structural layer is adjusted and improved based on a structure of the cable. A filling layer material combines glass fiber, a flame retardant, carboxymethyl cellulose, a crosslinking agent, a plasticizer, polytetrafluoroethylene, polyamide wax, mullite powder and anti-aging composition, the weight ratio among the glass fiber, the flame retardant, the carboxymethyl cellulose, the crosslinking agent, the plasticizer, the polytetrafluoroethylene, the polyamide wax, the mullite powder and the anti-aging composition is reasonably allocated, and the prepared cable has excellent flexibility and flame retardancy. The structure of the cable is further improved and innovated. Stabilizing devices are correspondingly arranged between a cable core and an insulating layer and between the filling layer and a sheath, and the strength, toughness and service life of the cable are improved. The cable with the performances of high flexible, anti-aging and flame retardant is prepared by the organic combination of the insulating layer, the filling layer and a sheath structure.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic material processing, and in particular relates to a highly flexible cable used in a photovoltaic system. Background technique [0002] The amount of cables used is increasing with the construction of photovoltaic power generation system facilities. The cable includes a conductor, an insulating layer, a filler and a sheath. The cable material refers to the insulating layer that wraps the conductor, the sheath that protects the cable, and the filler filled between the insulating layer and the sheath. The formula of the cable material directly affects the cable. Physical properties such as flexibility, flame retardancy and insulation. At present, the cables used in photovoltaic power generation systems have poor flexibility and are easy to break and damage, which affects the normal use of the cables. [0003] Therefore, in order to overcome the above disadvantages, it is necessary to provide a...
