Cable and production method for solar energy photovoltaic power generation system

Abstract

The invention discloses a manufacture method for the cables applied in solar photoelectrical generation systems, comprising: (1) providing and twisting a plurality of conductors into a cable core; (2) covering the cable core via one linear polyethylene layer to form a blank insulation layer; (3) processing the blank insulation layer via an electronic accelerator into an insulation layer of adult polyethylene structure; (4) covering the insulation layer by one linear polyethylene layer to form a blank outer coat; (5) processing the blank outer coat via the electronic accelerator into an outer coat of adult polyethylene structure, to obtain the cable applied in solar photoelectrical generation systems. The cable core is coated by an insulation layer and an outer coat of adult type polyethylene, to obtain long service life, good mechanical performance, good chemical corrosion resistance, strong ultraviolet resistance and good resistance to serious environment. The invention further discloses a cable applied in solar photoelectrical generation systems.

Description

technical field [0001] The invention relates to a cable manufacturing method, in particular to a cable for a solar photovoltaic power generation system with good mechanical properties, long service life and strong environmental adaptability. Background technique [0002] With the intelligent development of mechanical equipment, cables used to transmit signals have been widely used in industrial production, agricultural production, transportation, engineering equipment and military facilities and other fields. The application of cables is mainly divided into three categories: power system, information transmission system and engineering equipment, and instrumentation system. With the development of social economy, cable varieties are constantly updated and improved, and the production volume continues to increase. At the same time, with the depletion of non-renewable resources such as oil, coal, and natural gas, people's demand for new energy has reached unprecedented attent...

Problems solved by technology

However, the current solar photovoltaic power generation system uses a layer of polyvinyl chloride as the insulation for the cable. The cable with this material and structure cannot withstand the long-term rain and sun in the outdoors. Under the natural harsh environment and corrosion, the surface of the cable will crack, delaminate or even break. The aging speed of the ethylene coating is accelerated under the corrosion of ozone in the atmosphere, which greatly reduces the mechanical properties of the cable itself, shortens the service life of the cable, and causes paralysis of the solar photovoltaic power generation system and damage to the components. Severe cases can lead to the occurrence of leakage accidents in the solar photovoltaic power generation system
