Photovoltaic solar cable system wiring skills


The circuit of the photovoltaic system is divided into a DC part and an AC part.

The two parts of the circuit need to be wired separately. The DC part is connected to the components, and the AC part is connected to the grid. There are many DC cables in medium and large power stations. In order to facilitate future maintenance, the wire number of each cable should be firmly attached.

Separate strong and weak wires. If there are signal wires, such as 485 communication, they should be routed separately to avoid interference. When routing the cables, prepare conduits and bridges, and try not to expose the cables. It will look better when the cables are routed horizontally and vertically.

Try not to have cable joints in the threading pipes and bridges, because maintenance is inconvenient. If aluminum wires are used instead of copper wires, reliable copper-aluminum transfer terminals must be used.

In the entire photovoltaic system, cables are a very important part, and the cost of the system is increasing.

When designing the power station, we need to save the system cost as much as possible on the premise of ensuring the reliable operation of the power station.

Therefore, the design and selection of the AC and DC cables of the photovoltaic system is particularly important.
