Everything You Need to Know About Solar CablesSolar technology will be one of the green energy technologies of the future, and solar energy or photovoltaic (PV) is becoming more and more widely used in China. In addition to the rapid development of government-backed PV power plants, private investors are actively building plants and planning to put into production solar modules that will be sold worldwide.Solar cables, or PV-specific cables, have a conductor section of copper conductors or tinned copper conductors, an insulation layer of irradiated cross-linked polyolefin insulation, and a sheath of irradiated cross-linked polyolefin insulation. Photovoltaic power station in a large number of DC cables need to be laid outdoors, harsh environmental conditions, the cable material should be based on resistance to ultraviolet light, ozone, severe temperature changes and chemical erosion, moisture, sunlight, cold, heat, UV resistance, some special environments also need to prevent acid and alkali chemicals.Common material cable in this environment for a long time, will lead to the cable sheath fragile, and even decomposition of the cable insulation layer. These conditions will directly damage the cable system, but also increase the risk of cable short-circuit, in the medium and long term, the possibility of fire or personal injury is also higher, greatly affecting the life of the system.The advantages of solar cables compared to ordinary cables are:Solar cables are often exposed to sunlight, and solar systems are often used in poor environmental conditions, such as low temperatures and ultraviolet radiation. In good weather at home or abroad, the maximum temperature at the site of the solar system will be up to 100°C.Ordinary cables can generally be adopted from a variety of materials such as polyvinyl chloride (PVC), rubber, elastomer (TPE) and cross-linked polyethylene (XLPE) and other high-quality interwoven link materials, but unfortunately the maximum rated temperature of ordinary cable work is 90, and even the rated temperature of 70 ℃ polyvinyl chloride insulated cable is often used outdoors, but can not meet the high temperature, UV protection, cold requirements.Solar cable, in placement and application, the cable can be wired on the sharp edge of the roof layout, while the cable must withstand pressure, bending, tension, interwoven tensile load and resistance to strong blows superior to ordinary cable. If you use ordinary cable, the sheath anti-UV performance is poor, resulting in the aging of the cable sheath, which affects the service life of the cable, can lead to cable short circuit, fire and staff danger injury and other problems. Solar cable insulation sheath after irradiation, with high temperature resistance, UV radiation, oil resistance, cold resistance and other properties, service life of 25 years or more.If you want to know more, please feel free to contact us >>

What are the common faults and causes of solar cables? The common faults of solar cables and wires include mechanical damage, insulation damage, insulation damp, insulation aging and deterioration, over voltage, cable overheating faults, etc. When the above-mentioned faults occur on solar cables and wires, for electricians, the power supply of the faulty solar cables should be cut off and the fault point should be found. Check and analyze the failure, and then carry out maintenance and testing. Cut-off can be resumed after troubleshooting. The most direct cause of solar cable failure is that the insulation strength is not enough and it is often broken down.The main causes of solar cable failures are:1. Overload operation of solar cables: long-term overload operation will increase the temperature of solar cables, aging insulation, resulting in insulation breakdown and reducing construction quality:2. Electrical aspects: The construction process of the solar cable head cannot meet the requirements, and the sealing performance of the solar cable head is poor. When moisture intrudes into the solar cable, the insulation performance of the solar cable decreases, and no protective measures are taken during laying of the solar cable, the protective layer is damaged, and the insulation is reduced.3. During installation: the underground drainage is poor, and the solar cable is soaked in water for a long time, which damages the insulation strength. If the working well is too small, the bending radius of the solar cable is not enough, and it will be damaged by external force after a long time. Mainly in the brutal construction of municipal construction machinery, digging and cutting solar cables.4. Corrosion: The protective layer has been subjected to chemical corrosion or solar cable corrosion for a long time, resulting in failure of the protective layer and reduced insulation.5. The quality of the solar cable itself or the accessories of the cable head is poor, the sealing of the solar cable head is poor, and the insulating glue is dissolved and cracked. The resonance phenomenon that occurs on the platform is the disconnection of the photovoltaic cable, which leads to the formation of the phase capacitance and grounding capacitance of the solar cable and the excitation inductance of the distribution transformer. resonant circuit, thereby exciting the ferromagnetic resonance.In short, solar cables will inevitably have various faults during laying or daily use. When we deal with these problems, we need to repair the faults, so we need to pay attention to the safety of solar cables at any time.
