Zinc-Aluminum-Magnesium Photovoltaic Cable Tray

Zn-Al-Mg photovoltaic cable tray is made of Zn-Al-Mg alloy coated steel plate, which is a cable support and protection structure specially designed for photovoltaic (solar) power generation systems. It has various properties and is suitable for harsh environments such as outdoor photovoltaic power stations.

Detailed Introduction

Material composition: Zinc is the main component, with about 5-11% aluminum, about 2-3% magnesium and trace elements such as silicon added to form the Zn-Al-Mg alloy coating. The substrate is generally steel (such as Q355).

- Product features

- Strong corrosion resistance: The coating can form a dense protective film, with excellent resistance to salt spray, damp heat, acid and alkali corrosion. Its service life can reach 2 to 5 times that of ordinary galvanization, and the cut and edge parts have self-repair ability.

- Good rust resistance: It is not easy to oxidize and rust, the surface color is stable, and it can maintain a good state even after long-term exposure to a humid environment.

- Crack resistance and impact resistance: The alloy has good ductility and adhesion, is not prone to cracks or delamination during processing, and has both strength and toughness, which can withstand the stress test during transportation and installation.

- Lightweight: Adopts thin-walled high-strength steel plus Zn-Al-Mg coating to reduce weight and lower the load of photovoltaic supports.

- Adapt to photovoltaic needs: Open or ladder designs are available to facilitate heat dissipation of cables, and low-reflection surface treatment avoids affecting the efficiency of photovoltaic panels.

- Structural design: Integral bending forming reduces welding points to avoid damaging the coating, and drain holes are designed to prevent accumulated water from causing corrosion.

- Application scenarios: Mainly used in photovoltaic power stations to support DC and AC side cables; also suitable for harsh environment areas such as coastal areas, high humidity areas and industrial pollution areas, as well as building integrated photovoltaic (BIPV) systems and other scenarios.

- Installation and maintenance: Adopts weld-free assembled design (such as bolt connection), which is easy to install; maintenance is reduced due to its excellent corrosion resistance.

- Service life: Up to more than 30 years.
