Analysis of The Construction of Photovoltaic Cables Need To Pay Attention To Three Issues

Photovoltaic cable laying construction is an extremely important project, in order to ensure its normal operation, from time to time, if there is a failure, it must be laid to exclude the possibility of problems, and the premise of excluding the problem lies in the construction of the cable, the next, XSD cable will help you solve the problem, and for you to solve the problems encountered when laying the cable, take a look.

1, The current caused by eddy current problems

Photovoltaic cable in the construction process, some use steel bracket, some use steel sheath, some use cable clamps and overhead laying. Can form any steel (iron) closed loop around the photovoltaic cable, the above phenomena are likely to produce eddy currents, especially worth mentioning is that in the high current photovoltaic cable system, eddy currents are greater, in the construction process, measures must be taken to prevent the formation of steel (iron) closed loop around the cable and thus prevent the cable from eddy current phenomenon.

2, The cable rotation caused by mechanical damage

Individual type specifications too large photovoltaic cable because of the larger outside diameter and thus lead to transport and laying difficulties, at the same time, the requirements of the turning radius is also very strict, if the corner amplitude is too large, it is very likely to make the conductor internal mechanical damage, and mechanical damage is caused by the insulation strength of the cable until the failure, in the equipment connection, the appropriate shortening of the connection length of the middle phase cable head, so that the three-phase cable head is not subject to external force. Practice has proved that the operation of good results.

3, The low-voltage photovoltaic cable grounding problems

In the public low-voltage photovoltaic cable, due to the three-phase load is not equal, if the use of metal-sheathed cable, must consider the grounding of the metal sheath, at the same time, and should ensure that the metal sheath at any point is not grounded, the normal induction voltage should not be greater than 100V, I think, in the low-voltage cable network, all cable joints should be set up grounding pole (network), the metal sheath should be reliably grounded.

Well, said three points about the construction of photovoltaic cables worth noting the three issues, you get it, at the same time, you also want to know more related news and information, we recommend to continue to pay attention to our company XSD Cable official website, the follow-up will also push you more related information, please look forward to.
