When installing 10mm2 solar cable, what we should notice?

In the construction of solar energy, 10 square meters of photovoltaic cable is a relatively common specification of photovoltaic cables, and it is also a specification often used by different solar photovoltaic project construction teams. Different problems will inevitably occur in the use of solar energy construction masters. The common problems are summarized as follows:

What are the problems that are prone to occur in the construction of 10 square photovoltaic cables

The laying and construction of 10 square photovoltaic cables is an extremely important project. In order to ensure its normal operation, if failures occur from time to time, the possibility of problems must be eliminated when laying, and the premise of eliminating problems is the construction of 10 square photovoltaic cables.

1. Eddy current problem caused by current

In the construction process of 10 square photovoltaic cables , some use steel brackets, some use steel protection tubes, and some use 10 square photovoltaic cable clips and overhead laying. Any steel (iron) closed loop can be formed around the 10 square photovoltaic cable, and the above phenomena may produce eddy currents. It is particularly worth mentioning that in the large current 10 square photovoltaic cable system, the eddy current is large. During the construction process, measures must be taken to prevent the formation of steel (iron) closed circuits around the cables and to prevent eddy currents from 10 square photovoltaic cables.

2. Mechanical damage caused by the rotation of 10 square photovoltaic cables

Some oversized 10 square photovoltaic cables are difficult to transport and lay due to their large outer diameter. At the same time, the requirements for turning radius are also very strict. If the corner is too large, there is a high possibility of mechanical damage inside the conductor. It is caused by the dielectric strength of 10 square photovoltaic cables until the failure occurs. When connecting the equipment, appropriately shorten the connection length of the middle-phase 10 square photovoltaic cable head, so that the three-phase 10 square photovoltaic cable head is not affected by external force. Practice has proved that the operation effect is good.

3. Grounding problems of medium and low voltage 10 square photovoltaic photovoltaic cables

In the public medium and low voltage 10 square photovoltaic cable, because the three-phase load is not equal, if the metal sheathed 10 mm2 solar cable is used , the grounding problem of the metal sheath must be considered. At the same time, it should be ensured that any point of the 10 square photovoltaic cable sheath is not grounded, and the normal induced voltage should not be greater than 100V. Many people think that in the medium and low voltage 10 square photovoltaic cable network, all cable joints should be equipped with grounding electrodes (nets), and the metal sheath should be reliably grounded.

In a word, the laying construction of 10 square meters of photovoltaic cables is a relatively important facility. In order to ensure smooth construction and future use without problems, it is necessary to eliminate possible problems during laying, because the premise of eliminating problems is 10 square meters of photovoltaics. Construction of cables.
