Zinc-aluminum-magnesium photovoltaic cable tray is beautiful and practical.
Zinc-aluminum-magnesium photovoltaic cable trays are made of zinc-aluminum-magnesium alloy coated steel plates. They are cable support and protection structures specially designed for photovoltaic (solar) power generation systems, with various properties and suitable for harsh environments such as outdoor photovoltaic power stations.
Detailed Introduction
Material Composition: Based on zinc, adding about 5-11% aluminum, about 2-3% magnesium and trace elements such as silicon to form a zinc-aluminum-magnesium alloy coating. The base is generally steel (such as Q355, etc.).
- Product Features
- Strong Corrosion Resistance: The coating can form a dense protective film, with excellent resistance to salt spray, humidity, acid and alkali corrosion. Its service life can reach 2 to 5 times that of ordinary galvanized products. The cut edges have self-repairing ability.
- Good Rust Prevention 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 and Impact Resistance: The alloy has good ductility and adhesion, so it is not easy to crack or delaminate during processing. It has both strength and toughness, and can withstand the stress during transportation and installation.
- Lightweight: Adopts thin-walled high-strength steel plus zinc-aluminum-magnesium coating, reducing weight and the load on the photovoltaic support.
- Adapted to Photovoltaic Requirements: It has designs such as open or ladder type to facilitate cable heat dissipation. The low-reflection surface treatment avoids affecting the efficiency of photovoltaic panels.
- Structural Design: The overall bending molding reduces welding points to avoid coating damage. It has a drainage hole design to prevent water accumulation and corrosion.
- Applicable Scenarios: Mainly used in photovoltaic power stations to support DC-side and AC-side cables. It is also suitable for harsh environment areas such as coastal areas, high humidity areas, industrial pollution areas, and building-integrated photovoltaic (BIPV) systems, etc.
- Installation and Maintenance: Adopts a weld-free assembled design (such as bolt connection), which is convenient for installation. Due to its good corrosion resistance, it requires less frequent maintenance.
- Service Life: Can reach more than 30 years.
- Cost Benefit: The initial cost is slightly higher than that of ordinary cable trays, but the comprehensive maintenance cost is relatively low.
