Do galvanized cable trays require jumper wires?

According to electrical installation standards, galvanized cable trays require jumper wires. Galvanized cable tray refers to a cable tray made of galvanized materials, which has good corrosion resistance and fire resistance, and can meet the requirements of indoor and outdoor cable laying. In electrical installation, jumper wires are a common connection method used to connect different potentials in a circuit together to avoid safety issues such as short circuits and electric shocks. For galvanized cable trays, due to the corrosion-resistant galvanized layer on their surface, they will not have direct electrical connections with ordinary wires and cables. However, the following points should still be noted when setting up jumper wires:

Galvanized cable trays require jumper connections to ensure the safety and reliability of the circuit.  

2. The connection of jumper wires needs to comply with regulatory requirements, and is generally connected by welding, bolt connection, and other methods.  

3. Attention should be paid to fire prevention, moisture prevention, and other issues when connecting jumper wires to avoid fire or electrical accidents.  

4.When setting up jumper wires, factors such as the span, suspension height, and cable size of the bridge should also be considered to ensure construction quality and cable safety.  

In short, galvanized cable trays require jumper wires. When setting up jumper wires, it is necessary to comply with relevant regulatory requirements, pay attention to fire and moisture prevention issues, and ensure construction quality and cable safety.
