Problems solved by technology

[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.

Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 as shown, figure 1 A high-performance tensile and compression double-core photovoltaic cable proposed for the present invention includes a cable core, an armor layer 2 and a sheath layer 3 .

[0026] The cable core is composed of two wire cores 4, and during specific implementation, the cable core is formed by twisting the wire cores. The inner liner 1 is arranged on the outer periphery of the cable core. In practice, the inner liner 1 is made of a 125°C radiation cross-linked elastomer material. The 125°C irradiation cross-linked elastomer material has the characteristics of low-smoke, halogen-free, flame-retardant, high toughness, and good elasticity, which can effectively ensure that the insulation of the cable is not da...

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...
