Do you use jumper wires for stepped hot-dip galvanized bridge channels? To answer this question, you need to understand the material properties of stepped hot-dip galvanized cable bridge channels and the purpose of jumper wires. The material of stepped hot-dip galvanized bridge channels is typically cold.../Hot-rolled steel processed through hot-dip galvanizing or directly from galvanized sheets with a zinc coating on the surface. Whether cold/Hot-rolled steel or galvanized sheet are both steel metals, naturally containing conductive metal ions, so the stepped hot-dip galvanized bridge can conduct electricity smoothly after connection. Does the stepped hot-dip galvanized bridge use jumper wires?2Purpose of the junction wireGB 50303-2015"Code for Acceptance of Construction Quality of Electrical Engineering Projects, the ladder-type hot-dip galvanized bridge and bracket wiring must have at least two places using jumper wires for grounding or connecting to the main neutral line. For the ladder-type hot-dip galvanized bridge, it can be connected without jumper wires, but the ends of the connecting strips on the ladder-type hot-dip galvanized bridge must have at least..."2A fixed bolt ensures smooth electrical conductivity between bridge sections. It prevents leakage occurrences. In summary, for stepped galvanized bridge sections, it is not necessary to use jumper wires between two sections. However, at least two points on the bridge circuit require jumper wires for external connections to maintain conductivity, preventing bridge section electrical leakage accidents.
