In recent years, under the support and guidance of relevant national policies, the solar solar power industry has developed rapidly, and the installed capacity of the solar power stations has increased year by year.
solar cables are often exposed to sunlight, and solar systems are often used in harsh environmental conditions, such as high temperature and ultraviolet radiation. In Europe, sunny days will result in on-site temperatures of solar systems up to 100 ° C. At present, All kinds of materials we can use include PVC, rubber, TPE, and high-quality cross link materials. Unfortunately, rubber cables with a rated temperature of 90 ° C and PVC cables with a rated temperature of 70 ° C are often used outdoors. At present, the national golden sun project is frequently launched. In order to save costs, many contractors choose ordinary cables instead of special cables for solar energy systems It is obvious that this will greatly affect the service life of the system.
The characteristics of solar cable are determined by its special insulating material and sheath material, which we call cross-linked PE. After irradiation by the irradiation accelerator, the molecular structure of the cable material will be changed, so as to provide three aspects of its performance. Resistance to mechanical loads in fact, during installation and maintenance, the cables can be laid on the sharp edge of the roof structure, and the cables must bear pressure, bending, tension, cross tensile load, and strong impact. If the strength of the cable sheath is not enough, the cable insulation will be seriously damaged, which will affect the service life of the whole cable, or lead to a short circuit, fire, and personal injury.
The solar cable can be applied to solar power stations under different environmental conditions to ensure its long-term safe operation, while the conventional cable is difficult to achieve this purpose. Therefore, in the construction project of a solar power station, the selection of solar cable instead of conventional cable can effectively ensure the long-term and stable operation of the power station, so as to ensure the good long-term operation benefit of the power station.
