Double bars are better. Compared to a single cable trench, double cable trenches can provide better safety and reliability, while better protecting cables and reducing the risk of breakdowns. In addition, double cable trenches can better support the weight of the cables, reduce the pressure on the foundation, and reduce the risk of foundation settlement. Therefore, using double cable trenches is a more common and reliable choice when constructing photovoltaic power plants.
It is not necessary to use photovoltaic cables. The jacket of ordinary cables has poor UV resistance, which causes the outer jacket of the cable to age, thereby affecting the life of the cable, which may lead to cable short circuits, fires or dangerous injuries for staff, etc. The difference between photovoltaic cables and cablesordinary lies mainly in insulation and sheath materials. The material used in photovoltaic cables is radiation treatment. This material is resistant to high temperature, cold, oil, aging, ultraviolet. and environmental protection, but the price is also a little higher
