How To Lay Photovoltaic Cables To Reduce Costs And Save Costs

In the solar photovoltaic power generation system, the construction cost of photovoltaic cables is generally relatively large, and the choice of laying method directly affects the construction cost, so how to correctly choose the most cost-effective laying method of photovoltaic cables, it is more important for us to plan the layout reasonably one ring. Cable design work. When it comes to the laying method of photovoltaic cables, factors such as cable specifications, quantities, engineering conditions, and laying environment should be considered comprehensively, and the selection should be based on the principles of reliable operation, convenient maintenance, and technical and economical rationality.

The laying of DC cables in photovoltaic power generation projects mainly includes laying through pipes, laying in trenches, laying in cable trenches, laying in tunnels, laying directly buried in sand, laying bricks, etc. The laying of AC photovoltaic cables is similar to that of other cables. Generally used in power systems.

Photovoltaic cables are generally used for the connection between photovoltaic modules. The cables need to have a small cross-sectional area and be able to carry a large voltage, usually up to 1500V. The cables are bundled with the module bracket or buried directly through the pipeline. Generally, the following points need to be considered when laying:

1. When laying cables, the connecting cables between photovoltaic modules or the connection between various modules and photovoltaic cables, and photovoltaic cables should use module brackets as channel support and fixation as much as possible, which can reduce the impact of environmental factors to a certain extent.

2. When laying photovoltaic cables, the master worker should apply force evenly and not over-tighten. Generally, the site of a photovoltaic power station is open to the outside, and the temperature difference between day and night is very large. Everyone knows that photovoltaic cables should be prevented from thermal expansion and contraction.

3. For the photovoltaic cable lead-out lines on the surface of the building, the overall appearance of the building should be considered. The laying position should avoid laying the cables on the sharp edges of walls and brackets, so as not to cut or wear the insulation layer of photovoltaic cables and cause damage, or to cut off the wires due to excessive shearing force. cause quality problems. At the same time, it is also necessary to consider whether the safety of the cable line is safe.

4. Before planning to build a solar photovoltaic power station, it is necessary to reasonably plan the laying path of photovoltaic cables, reduce the intersection of photovoltaic cables, and lay them in accordance with the site conditions as much as possible, so as to reduce the amount of earth excavation and the number and cost of photovoltaic cables used during the construction process.

5. It is believed that most of the photovoltaic cables are laid outdoors. Generally, the cable joints connected to solar energy can use protective tubes, and use component brackets as channels for fixed laying.

Building a photovoltaic power station requires a relatively high cost, and the laying of photovoltaic cables is particularly complicated. Combined with the site, a well-planned photovoltaic cable laying method will reduce a lot of costs and the durability of solar photovoltaic power stations.
