Resistor connected between the ends of the bridge should not exceed 0.00033 ohm, ground hole should clear insulating coating. In 1KV and below the neutral grounding system, the neutral grounding powered devices connected to the system ground. Cut off the power supply is equipped with dynamic loading at Xuan, the long direction of the metal bridge stage cross-sectional area shall not be less than the specified value. 3, the total length of the bridge along the ground lay another trunk, each (including non-linear segment) should be at least a little bridge reliable connection and grounding lines. 4, the vibration places, at the site of the grounding connections shall be equipped with a spring ring.

The cable network or electrical interference protective external (eg: there etchant Hugh, combustible dust and other environmental) impacts upon request, should be used (FB) class trough composite corrosion shielded cable tray (with lid) 2, strong corrosive environments should be used (F) corrosion retardant epoxy composite cable tray. Corbel, bracket, but also the choice of the same material, to improve the life, tray cable tray and accessories. Easy to fouling and the need to cover environmental or other outdoor venues should be stamped plate. 3, in addition to the above, according to the site environmental and technical requirements are also optional tray, trough, stepped glass corrosion retardant cable tray or steel ordinary type bridge. Easy to fouling and the need to cover environmental or other outdoor venues should be stamped plate. 4, or outdoors in a public passage across the road segment, the bottom rung of the bottom plate or tray should be added in this section. Public access across a large span of time, can increase the load capacity of the bridge or optional rack rows according to user requirements. 5, large span (> 3m) to choose composite bridge (FB). 6, Outdoor refers to the choice of composite epoxy resin tray (F).
