Vai jūs zināt, par ko pievērst uzmanību, uzstādot PV kabeli?

1. Cable inspection

Carefully inspect the specifications the PV Cable, whether it meets the design specifications, whether there is any damage on the surface, such as cracking, scratches or deformation, and whether there is aging or cracking of the insulation and protective layers. Make sure that the quality inspection report of the cable is complete.

2. Circuit laying

Based on the layout and planning diagram the photovoltaic power station, scientifically plan the laying route of the PV Cable to prevent the crossing and superposition of PV Cable, unnecessary bends, and thus improve the performance and safety of the system. When choosing a path, avoid sections that are prone to mechanical damage, corrosion, or waterlogging, and that the selected path is convenient for future maintenance and inspection work.

3. Insulation treatment

After completing the connection of the PV Cable, insulation treatment measures be implemented to prevent leakage and short circuit accidents. For the insulation treatment of the photovoltaic cable and the junction, insulation tape or heat shrink tubing is generally used wrapping. During the operation, it should be ensured that the insulation material is tightly covered, ensuring that there are no gaps or bubbles. When using heat shrink tubing, the specified procedures should be strictly followed to ensure its uniform shrinkage, thus achieving the desired insulation effect.
