Cable device

Abstract

The invention discloses a cable device, which comprises more than two groups of insulated wire cores. Each insulated wire core, from inside to outside, comprises a copper conductor, a high-flame retardance polyester tape isolation layer and an irradiation cross-linking insulation layer sequentially. A cooling filling layer is arranged outside the irradiation cross-linking insulation layer. A protection layer is arranged outside the insulated wire cores. The protection layer, from inside to outside, comprises a halogen-free low-smoke flame-retardant cross-linking polyolefin inner sheath layer, a stainless steel wire braiding and enhancing layer and a halogen-free low-smoke flame-retardant cross-linking polyolefin outer sheath layer sequentially. The cable device has the advantages of safety, reliability, good heat resistance, high temperature resisting performance, long service life, and small size and mass.

Description

technical field [0001] The invention relates to a cable arrangement. Background technique [0002] With the improvement of human awareness of environmental protection, the world's energy structure is undergoing a huge transformation, that is, from a fossil energy system to a sustainable new energy system based on renewable energy. Solar energy has become the most important energy resource in the world. Therefore, solar power generation should be the main force to provide large-scale power in the future and the main direction of large-scale development. In recent years, the world's photovoltaic cell industry has developed rapidly. my country has developed a solar power generation capacity of 20MW, and photovoltaic power generation is one of the fastest growing industries in the world. As a supporting product for photovoltaic power generation, the market prospect of photovoltaic cables for solar power generation is also extremely broad. The solar photovoltaic cables currentl...

AI Technical Summary

Problems solved by technology

As a supporting product for photovoltaic power generation, the market prospect of photovoltaic cables for solar power generation is also extremely broad. The solar photovoltaic cables currently used have too many deficiencies, such as inability to withstand cross-stretching and strong impact, insufficient cable sheath strength, Susceptible to cracking and aging due to environmental influences

However, some cables that meet the safety factor are usually wrapped with a thick insulating layer and protective layer, and have a large volume and quality. These deficiencies restrict the development of solar photovoltaic cables.
