September 16, 2020. New energy cables can be generally divided into: PV cable , wind power cable, offshore oil platform cable, nuclear power station cable, electric locomotive cable, inland conventional and unconventional natural gas cable, etc.
For example, photovoltaic cables are often exposed to the sun, and solar systems are often used in harsh environmental conditions, such as high temperature and ultraviolet radiation. In Europe, sunny days will lead to the on-site temperature of the solar system up to 100 ° C. At present, we can use various sealing materials such as PVC, rubber, TPE and high-quality cross linking materials, but unfortunately, Rubber cables with a rated temperature of 90 ° C and even PVC cables with a rated temperature of 70 ° C are often used outdoors. At present, the National Golden Sun Project has been launched frequently. In order to save costs, many contractors choose ordinary PVC cables instead of special cables for solar systems. Obviously, this will greatly affect the service life of the system.
The characteristics of photovoltaic cable are determined by its special insulation material and sheath material, which we call cross-linked PE. After irradiation by irradiation accelerator, Cable material Its molecular structure will change, thus providing its various properties.
In fact, during installation and maintenance, the cable can be routed on the sharp edge of the roof structure. At the same time, the cable must bear pressure, bending, tension, cross tensile load and strong impact. If the strength of the cable sheath is not enough, the cable insulation layer will be seriously damaged, which will affect the service life of the cable, or lead to short circuit, fire, personal injury and other problems.
With the increasingly serious problem of air control, it has become a general trend to vigorously develop new energy industry. In this context, photovoltaic cable, wind power cable, nuclear power station cable, offshore oil platform cable, etc New energy cable It will gradually become the next breakthrough direction of the cable industry.
