Production process of photovoltaic cable with high temperature resistance and long service life

Abstract

The invention provides a production process of a photovoltaic cable with high temperature resistance and long service life, and relates to the technical field of photovoltaic cable manufacturing. The production process of the photovoltaic cable with high temperature resistance and long service life comprises the following specific steps: step 1, firstly, carrying out stretching annealing treatment on a copper conductor; 2, performing concentric compound stranding on the annealed copper conductor to obtain a cable core; 3, after the cable core is manufactured, the outer surface of the cable core is coated with an insulating layer through a plastic extruding machine; and step 4, after the insulation layer is coated, putting the insulation layer into cooling water for cooling treatment. After the insulation layer of the cable core is coated, the thickness of the insulation layer is detected by adopting an ultrasonic detection method, the eccentricity of the cable insulation layer can be measured, and the method has the characteristics of convenience in use, high speed, no harm to a human body, convenience in field use and the like; and the problem of service life of the cable caused by deviation of the thickness of the insulating layer is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cable manufacturing, in particular to a high-temperature-resistant and long-life photovoltaic cable production process. Background technique [0002] With the increase in the construction of solar photovoltaic power generation system facilities, the use of cables is increasing. The cables used in all photovoltaic systems should be flame retardant, fireproof, non-toxic, and resistant to sunlight aging. This will greatly promote the development of environmentally friendly cables for solar photovoltaic systems. Building cost-effective and profitable photovoltaic power plants represents the most important goal and core competence of all solar manufacturers. In fact, profitability does not only depend on the efficiency or high performance of the solar module itself, but also depends on a series of components that seem to have no direct relationship with the module. But all these components (suc...
