Many countries are still in the learning phase. There is no doubt that, in order to obtain the best profit, the industry enterprises, all need to have many years of experience in the field of solar energy applications and companies to learn.
Building an economically efficient and profitable photovoltaic power plant represents the most important goals and core competencies of all solar manufacturers. In fact, profitability depends not only on the efficiency of the solar module itself or high performance, but also can not be separated from a range of surface components without a direct relationship with the component. But all of these components (such as cables, connectors, junction boxes) should be selected based on the long-term investment objectives of the tender. The high quality of the selected components can be avoided due to high maintenance costs and the solar system can not be profitable.
For example, it is often not considered a key part of the wiring system that connects the PV modules to the inverter,
However, if the use of solar energy applications can not be used for cable, will affect the life of the entire system.
In fact, the solar system often used in harsh environmental conditions, such as high temperature and ultraviolet radiation. In Europe, when the sun will lead to the field temperature of the solar system up to **0 degrees C. At this point, we can use a variety of materials PVC, rubber, TPE, and high quality cross link materials. But it is a pity that the rated temperature for *0 DEG C rubber cable, and even rated temperature is *0 degrees of PVC cable often used outdoors. Obviously, this will greatly influence the service life of the system.
HUBER+SUHNER solar cable production has more than *0 years of history. European solar equipment using such cables has been in use for more than *0 years, and is still in good working condition.
Environmental stress
In terms of photovoltaic applications, outdoor use of materials should be based on UV, ozone, severe temperature changes and chemical erosion situation. In this kind of environmental stress, the use of low-grade materials, will lead to the cable sheath is fragile, and even break down the insulation layer of the cable. All these conditions will directly increase the loss of the cable system, while the risk of cable short circuit will increase, from the medium and long term, the possibility of fire or personnel damage is higher.
RADOX® HUBER+SUHNER; solar cable is an electron beam cross linked cable, rated temperature of **0 degrees C, in the equipment can withstand harsh climate environment and withstand mechanical shock. According to the international standard RADOX®, IEC**6; solar power cable, in outdoor environment, its service life is 8 times of rubber cable, is *2 times of PVC cable. These cables and components not only have the best weather resistance, ultraviolet and ozone resistance, and can withstand a greater range of temperature changes (e.g., from - *0 degrees C to **5 degrees C).
Manufacturers tend to use double insulated rubber sheathed cables (e.g., RNF H*7) to cope with the potential dangers of high temperatures. But the standard version of this cable is only allowed for the maximum operating temperature of *0 degrees C. In Europe, the roof can be measured as the temperature reached **0 degrees C.
RADOX® the rated temperature of the solar power cable is **0 C (****0 hours). This rating is equivalent to *0 C in the continuous temperature conditions can be used for *8 years; and when the temperature is less than *0 degrees C, the service life is longer. In general, the service life of solar equipment should be *0 to *0 years.
For all of these reasons, it is necessary to use a dedicated solar power cable and component in the solar system.
Anti mechanical load
In fact, during installation and maintenance, the cable can be wired to the sharp edge of the roof structure, while the cable is subjected to pressure, bending, tension, cross tension load and strong impact. If the cable sheath strength is not enough, then the cable insulation layer will be seriously damaged, thus affecting the life of the entire cable, or lead to short circuit, fire and personnel injury risk and other issues.
The radiation cross link of the material, with a higher mechanical strength. Cross linking process changed the chemical structure of the polymers, hot melt plastic material conversion for non fusible elastomer material, radiation cross link significantly improved the cable insulating material thermal properties, mechanical properties and chemical properties.
As the world's largest solar market, Germany has encountered all problems related to the selection of cables. Now in Germany, more than *0% of the equipment is dedicated to the use of solar energy applications RADOX® HUBER+SUHNER; cable.
RADOX® appearance quality
RADOX cable:
Perfect concentric degree of cable core
Sheath thickness
Smaller diameter and cable core distribution
Diameter of cable is larger (than RADOX cable diameter is *0%).
Sheath thickness uneven (caused by the surface defects of the cable)

The characteristics of photovoltaic cable are determined by the cable insulation material and the sheath material, we call it cross linked PE, after irradiation, the cable material
