High-flame-retardant tear-resistant photovoltaic cable

Abstract

The invention discloses a high-flame-retardant tear-resistant photovoltaic cable, and an outer wrapping layer comprises rubber layers and asbestos layers; the rubber layers wrap the asbestos layers up and down, a tear-resistant layer is located on the inner ring of the outer wrapping layer, the tear-resistant layer is composed of a framework, a rectangular bending plate and filling silica gel, a bending reinforcing layer is located on the inner ring of the tear-resistant layer, and the bending reinforcing layer is a metal hose. The cable also comprises an inner core fixing layer, and the inner core fixing layer is located in the center of the cable; the outer layer of the inner core fixing layer is hard rubber, the inner ring of the hard rubber is provided with crisscross supporting rubber, and a cable cell penetrates through the crisscross outline. According to the scheme, the improved tear-resistant layer is added, so the pulling toughness of the cable in the transverse direction and the longitudinal direction is improved, and the anti-tear layer is provided with a metal material, so the flame-retardant effect is improved, asbestos is added in the interlayer of the outer rubber layer to solve the flame retardance, and rubber fixing teeth are added in the inner core layer to solve the fixity of the cable core, so the pulling toughness is improved at the same time.

Description

technical field [0001] The invention relates to the technical field of cables, and specifically designs a high flame-retardant and tear-resistant photovoltaic cable. Background technique [0002] Photovoltaic cables are usually installed in the wild and uninhabited, and they are not frequently maintained. Therefore, their corrosion resistance and tensile strength need to be improved. In addition, the animals are active in the wild, and the cables buried underground are easy to be bitten and dragged by animals. If things go on like this, the cables are easy to In addition, photovoltaic cables are in line with market development needs and actively respond to the development of the national photovoltaic industry. Most of them are designed with ordinary PVC sheath materials. Pure PVC materials are flame-retardant and tear-resistant. Fragility is relatively weak. Contents of the invention [0003] The present invention provides a high flame-retardant and tear-resistant photovo...
