    Grounding lead-out device

    CHBY-D series grounding lead-out device is specially developed by our company for the speciality of subway grounding.

    Realize the grounding of all power equipment of the subway station, connect the signal equipment grounding and lightning protection to the integrated grounding network

    Grounding lead-out device for effectively preventing groundwater seepage and achieving good current protection

    ★ In the subway grounding system, due to fault current stray, current protection requirements and high grounding grid,

    Under the structural bottom plate, when the electrical equipment of the subway station is grounded, it must be connected through the grounding down conductor.

    Ground connection to achieve reliable grounding, often directly from the structural bottom plate to lead the ground down conductor or through PVC

    This kind of measure is adopted under the tube, which is prone to aisle fault current spurs, current protection requirements, groundwater

    It is easy to seep out from the grounding lead line, and the grounding design requirements of the subway are not up to standard.

    ★The grounding lead-out device is made up of protective cylinder, water stop ring, grounding lead wire, insulation filling material, etc.

    The protection tube is made of non-magnetic stainless steel material, the grounding lead wire is made of copper, and the protection tube should be filled.

    Filled with insulating resin material}, with scientific material selection, reasonable structure, process selection, and stable quality.

    Advantages such as relying on, construction and installation are convenient. It can realize grounding of power equipment in subway station and signal equipment

    Ground, lightning protection grounding, integrated grounding grid can effectively prevent groundwater seepage and can reach well

    To the fault current stray protection requirements.
