What material is the shielding bridge?

Shielded cable tray is a metal tray used to protect wires and cables from electromagnetic interference (EMI). It is usually made of galvanized steel plate or aluminum alloy, which can effectively block electromagnetic fields and prevent interference and influence of electromagnetic waves. The requirement for shielding cable trays is to effectively prevent the influence of electromagnetic fields on internal wires and cables in an electromagnetic environment, while also ensuring the lowest electromagnetic radiation. To achieve this goal, shielding cable trays need to use materials with high conductivity, such as copper, galvanized steel plates, aluminum alloys, etc. In addition, shielded cable trays also need to have certain structural strength and durability to ensure their stability and safety during use. It should be noted that different application scenarios have different requirements for shielding cable trays, so the specific shielding effect needs to be evaluated based on the actual situation. Meanwhile, if the material selection or manufacturing process of the shielding bridge is improper, it may also lead to a decrease in its shielding effect. Therefore, when selecting and using shielded cable trays, comprehensive consideration should be given based on the actual situation.
