Photovoltaic Cable Aging Do Not Be Afraid, XSD Cable Teach You To Prevent

Photovoltaic cable aging is very common, the speed of cable aging and the quality of the wire and the use of the situation, in the case of constant use of the wire, the better the quality of the wire, the aging rate will be relatively slow so as to extend the service life, when the cable aging to a certain extent, if not maintained or replaced, continued use will cause some danger, therefore, we must regularly check the aging of the cable. So how do we check it? Next, XSD cable teach you to check in time, and then eliminate the security risks.

1, The insulation layer of the cable is exposed for a long time, it will be easy to be corrosive gas corrosion, so that the insulation performance gradually decline, gradually harden, become brittle and eventually directly off, at this time, it will not play the role of insulation, in fact, the most direct cause of failure of wire and cable aging is because of insulation degradation and breakdown, so we must focus on checking the insulation of the wire, carefully check its appearance, and observe the line along the insulation layer.

2, If you want to accurately determine the insulation state of the circuit, you can use the insulation resistance meter to measure the insulation of the circuit, different lines of insulation have different allowable values, for example: the insulation resistance of the 220V line in use should not be less than 0.22 megohm; the value of the rainy day should not be less than 0.1 megohm, if the measured insulation resistance value is less than the above value, it means that the insulation of the circuit has problems, of course, the cable Of course, the service life of the cable is different under different conditions of use, which requires you to deal with yourself!

3, If one of the above two situations, your side must be replaced in a timely manner relative to the appropriate cable, it is best to summarize the experience based on the causes of aging insulation in the past, choose the right cable, even if you choose the right photovoltaic cable, wiring this step can not be ignored, the environment selected by the wiring should be a dry environment around the cable to avoid moisture, if you really can not avoid the wiring in a more humid and wet environment If you can't avoid wiring in a wetter and more humid environment, then it is recommended to add cable protection sleeves to the cable, so that it is isolated from water and air, thus reducing the occurrence of cable accidents.

Well, summed up so much about how to prevent the aging of photovoltaic cables, you get it, at the same time, if you want to know more about the cable news information, we suggest that please pay attention to our XSD official website, the follow-up will be pushed for you more knowledge content.
