Perforated tray-type heat-dissipating photovoltaic cable tray is a cable tray specially designed for photovoltaic power generation systems. It adopts a tray-type structure with a perforated design, and is mainly used to lay various cables in photovoltaic systems. It can provide support, protection and a good heat dissipation environment for cables, and is an important component of photovoltaic power transmission systems.

Detailed Introduction

Structural features:

- It adopts a tray-type structure, usually composed of a perforated bottom plate and side panels, or a slotted component with holes at the bottom made by punching and bending a whole plate, which is a semi-sealed cable tray.

- There are many evenly distributed small holes on the surface. These small holes are the key design for its heat dissipation, which is conducive to air circulation.

- Materials and processes:

- Common materials include galvanized steel. The galvanized layer can provide good corrosion resistance, adapt to complex outdoor environments and resist natural erosion.

- There are also products made of materials such as zinc-aluminum-magnesium alloy, which have strong corrosion resistance.

- Product features:

- Heat dissipation performance: The small hole design promotes air convection, reduces heat accumulation, and increases the contact area with air. It can effectively reduce the operating temperature of cables, extend the service life of cables and ensure the stable operation of photovoltaic systems.

- Large load-bearing capacity: The tray-type structure can meet the laying requirements of various cables in photovoltaic systems, and can bear a certain weight of cables.

- Light weight: The perforated design reduces the weight of the cable tray to a certain extent, which is convenient for installation and transportation, and reduces material costs.

- Good corrosion resistance: Galvanized and other material treatments give it good corrosion resistance, reducing the frequency of later maintenance and replacement.

- Easy to install: The structure is simple, the installation is convenient, the accessories are universal, and it is convenient for cable maintenance and wiring adjustment.

- Application scenarios: Mainly used in photovoltaic power generation systems, including ground power stations, distributed power stations, rooftop power stations, etc. It can be used to lay connection cables between photovoltaic modules, transmission cables between inverters and booster stations, etc.

- Performance advantages:

- Good heat dissipation can reduce power loss and fault risks caused by overheating of cables, and improve the overall efficiency of photovoltaic systems.

- Longer service life and lower operation and maintenance costs due to its corrosion resistance and structural design.

- Installation and maintenance: It is easy to install and can be assembled with conventional connectors. Maintenance is simple. Due to its good corrosion resistance, there is no need for frequent anti-corrosion treatment, only regular inspections of the cable tray and cable operating conditions are required.
