Base station mesh cable trays are resistant to low temperatures
Trays can be supported by 1. 5 m brackets (maximum span - 2. 5m), Wire mesh cable tray systems can be safely used in places where the temperature ranges between -40'C and +150'C without any change to their characteristics. As temperature decreases, low-carbon steel products will loose ductility slowly until a certain point where the ductility rapidly decreases by over 50% within a very small. As temperature decreases, low-carbon steel products will loose ductility slowly until a certain point where the ductility rapidly decreases by over 50% within a very small temperature range. This point is called the ductile-to-brittle transition and occurs in all unalloyed, low-carbon steel. At temperatures below - 20 °C, the material will be any other purpose than. Among the many options available, stainless steel wire mesh cable trays have grown significantly in popularity—especially for environments that demand excellent ventilation, corrosion resistance, and future flexibility.
