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: Taking zinc as the main component, add about 5-11% aluminum, about 2-3% magnesium and trace elements such as silicon to form a Zn-Al-Mg alloy coating. The substrate is generally steel (such as Q355, etc.).
- Product features
- Strong corrosion resistance: The coating can form a dense protective film, with excellent salt spray, damp heat, acid and alkali corrosion resistance, and its service life can reach 2-5 times that of ordinary galvanization. It has self-repair ability at the cut and edge parts.
- Good antirust performance: It is not easy to oxidize and rust, the surface color is stable, and it can maintain a good state even when exposed to a humid environment for a long time.
- Crack resistance and impact resistance: The alloy has good ductility and adhesion, is not easy to crack or delaminate during processing, has both strength and toughness, and can withstand the test of transportation and installation stress.
- Lightweight: Adopt thin-walled high-strength steel plus Zn-Al-Mg coating to reduce weight and lower the load of photovoltaic supports.
- Adapt to photovoltaic needs: There are open or ladder designs to facilitate heat dissipation of cables, and low-reflection surface treatment to avoid affecting the efficiency of photovoltaic panels.
- Structural design: The overall bending forming reduces welding points to avoid damage to the coating, and there is a drain hole design to prevent accumulated water from causing corrosion.
- Application scenarios: Mainly used in photovoltaic power stations to support DC and AC side cables; it is also suitable for harsh environment areas such as coastal areas, high humidity areas, industrial pollution areas and photovoltaic building integration (BIPV) systems, etc.
- Installation and maintenance: Choose weld-free assembled design (such as bolt connection), which is easy to install; maintenance: because of its good corrosion resistance, frequent maintenance is not needed.
- Service life: up to more than 30 years.
