Solar Cable Reliable Insulation And Mechanical Properties
- Aug 11, 2017 -

Solar Cable technology will become one of the future green energy technologies, solar or photovoltaic (PV) in China increasingly widely used, in addition to the rapid development of government-supported photovoltaic power plants, private investors are actively building, plans to put into production in the global sales Of the solar modules.

Many countries are still in the learning stage. There is no doubt that, in order to obtain the best profits, industry companies, need to have those who have years of experience in Solar Cable applications and countries to learn.

The construction of cost-effective, profitable PV plants represents the most important goals and core competencies of all solar manufacturers. In fact, profitability depends not only on the efficiency or high performance of the solar module itself, but also inseparable from a series of components that appear to have no direct relationship with the component. But all of these components (such as cables, connectors, junction boxes) should be based on the long-term investment objectives of the tenderer to choose. The high quality of the selected components avoids the inability of the solar system to be profitable due to high maintenance and maintenance costs.

For example, people generally do not regard cabling systems that connect PV modules and inverters as critical components,

However, if you can not use a dedicated cable for solar applications, it will affect the service life of the entire system.

In fact, solar systems are often used in harsh environmental conditions, such as high temperature and ultraviolet radiation. In Europe, sunny days will result in solar system temperatures up to 100 ° C. At this point, we can use a variety of materials are PVC, rubber, TPE and high-quality cross-link material, but unfortunately, rated temperature of 90 ° C rubber cable, and even the rated temperature of 70 ° C PVC cable Also often used in the outdoors, obviously, this will greatly affect the system life.

Solar Cable Products:

       1, photovoltaic cable is a solar power system for the special cable, mainly for DC voltage side, power generation equipment and the connection between the connection between the components, the maximum voltage DC1.8KV photovoltaic power generation equipment system. Its resistance to weather, cold, high temperature, abrasion resistance, resistance to ultraviolet light and ozone resistance and other characteristics, at least 25 years of service life.

       2, high-quality oxygen-free tinned copper conductor to ensure its superior conductive effect, the high-energy electron accelerator radiation cross-linked high-performance insulation materials and jacket material plays an absolutely reliable insulation performance and mechanical properties of the product for green products , There are halogen-free low smoke, low halogen low smoke characteristics, in the event of a fire accident, the flame spread slowly, low smoke concentration, high visibility, small amount of harmful gas release, easy evacuation, and more time to deal with the fire.

Product structure features:

Conductor: 8030 aluminum alloy wire twisted conductor or five types of stranded tinned copper conductor conforming to UL certification standards according to IEC60228 + EN60228, VDE0295.5.
