High-performance dual-core photovoltaic cable resistant to tensile and compression

Abstract

The invention discloses a high-performance dual-core photovoltaic cable resistant to tensile and compression. The high-performance dual-core photovoltaic cable is characterized by comprising a cable core, an armor layer and a sheath layer, wherein the cable core comprises two wire cores, a lining layer is arranged at the periphery of the cable core, the armor layer wraps the periphery of the lining layer, the sheath layer is extruded at the periphery of the armor layer, each wire core comprises a reinforcement core, a conductor layer and an insulation layer, the conductor layer wraps the periphery of the reinforcement core, and the insulation layer is extruded at the periphery of the conductor layer. The high-performance dual-core photovoltaic cable has the characteristics of good high- and low-temperature resistant performance, high insulation performance, high tensile and compression resistance and light weight.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-performance tensile and compression double-core photovoltaic cable. Background technique [0002] At present, the photovoltaic power generation panel arrays used in photovoltaic power stations are connected to the combiner box by single-core unarmored special photovoltaic cables after being assembled in strings. These photovoltaic cables for confluence have only one layer of insulation and sheath outside the conductors. When they are connected, they are laid directly in the ground without taking protective measures. Even if some of them use pipes, the laying cost is very high. If the cables without armor protection are directly buried in the ground, because they are laid underground, The cable bears high pressure and is easily damaged by external forces, and in severe cases, it will cause a short circuit and fire. At the same time, the environment where the cables installe...

[0002] At present, the photovoltaic power generation panel arrays used in photovoltaic power stations are connected to the combiner box by single-core unarmored special photovoltaic cables after being assembled in strings. These photovoltaic cables for confluence have only one layer of insulation and sheath outside the conductors. When they are connected, they are laid directly in the ground without taking protective measures. Even if some of them use pipes, the laying cost is very high. If the cables without armor protection are buried directly in the ground, because they are laid underground, The cable bears a lot of pressure and is easily damaged by external forces. In severe cases, it will cause short circuit and fire

At the same time, the environment where the cables installed underground is humid, and the cables are easily corroded and damaged
