4 Factors Cause the Damage of Solar Cable

In recent years, solar photovoltaic power stations and other new energy series have been used by lots of household. These solar energy provide many households with irreplaceable convenience. Only solar power stations are generally installed in sunny places outdoors. electricity can be generated. but cannot be ignored is that the unstable weather is a test of the quality of xlpo solar photovoltaic cables. If the quality of pvf1 solar cables is not good, coupled with the changeable weather, it is easy to cause accidents. Then let's take a look at the impact of weather on solar photovoltaic cables.

HIGH TEMPERATURE

The hottest temperature in summer can be as high as 40 degrees. Solar photovoltaic cables also generate heat due to thermal effects during use. If the photovoltaic cable continues to work at high temperature, the aging of the insulating layer will be accelerated, causing the insulating layer to soften, crack and fall off. This is more common with bare cables or photovoltaic wires used outdoors.

LOW TEMPERATURE

In winter, especially in areas where the outdoor temperature is below zero, if the photovoltaic cable is placed outdoors or directly on the ground, it is likely to cause the outer skin of the product to fall off, because the outer skin of general photovoltaic circuit products is mostly ordinary plastic (PVC) Or rubber in a low temperature and zero degree Celsius environment will freeze and harden the cable, causing the entire photovoltaic cable product line to become hard and fragile. If a slight external force is applied, there is a good chance that the insulating layer will come off or be damaged.

HEAVY RAIN

During the rainy season, there is a period of wet conditions after a heavy rain. If the workmanship and production are not perfect in the production process of the dc cable for solar pv, the quality will not meet the standard, and eventually the photovoltaic cable will have a certain degree of various defects in the use process. If the photovoltaic cable is placed in a humid environment for a long time It is very likely that the phenomenon of "water tree aging" will occur, and eventually the cable insulation will be broken down, resulting in direct leakage, serious electric shock, fire and other serious accidents.

DEVASTATING WIND

In the outdoor environment, there are a few gusts of breeze from time to time. Under such circumstances, the insulating layer of the xlpo solar cable will also deteriorate slightly, and the insulating layer will harden earlier than that which is not blown by the wind. This is The inevitable is within our grasp. But we can't ignore the typhoon, which generally reaches the 12-level wind force. Maybe a typhoon will directly damage the entire solar power station system, and the same is true for the photovoltaic cable. The pv1f solar cable insulations may be damaged under this wind, and there are dangers such as short circuits.

Taking into account the above natural factors of weather, I suggest that when ordering pv1f solar cables, you must choose double insulation, and solar powered extension lead with irradiation cross-linked polyolefin insulation and irradiation cross-linked polyolefin outer sheath, because this kind of xlpo solar cable can operate stably for a long time at an ambient temperature of 40 to 90 °. With a little maintenance during use, the PV1-f solar cable can have a lifespan of more than 25 years.
