Product Details
Grounding leading-out device can effectively prevent groundwater
seepage and meet the requirements of stray current protection when
connecting power equipment grounding, signal equipment grounding,
lightning protection grounding and integrated grounding network on
subway platform. In the subway grounding system, due to the
protection requirements of fault current (stray current), the
grounding grid is located under its structural bottom plate.
Therefore, when the electrical equipment on the subway platform is
earthed, it must be connected to the grounding grid through the
grounding lead-off line to realize reliable grounding. In the past,
grounding leads are usually drawn directly from the structural
bottom plate or through PVC pipe. With this measure, it is easy to
fail to meet the protection requirements of the fault current
(stray current), and the groundwater is easy to leak out from the
grounding lead, which cannot meet the design requirements of subway
grounding. Grounding lead-out device is composed of protection
cylinder, water stop ring, grounding lead-out line, insulation
filling material and so on. The protective tube is made of
stainless steel, the grounding lead is made of T2 copper, the
hollow part of the protective tube is filled with insulating
material, which has the advantages of scientific material
selection, reasonable structure, advanced technology, stable and
reliable quality, convenient construction and installation, etc. It
can effectively prevent groundwater seepage when the ground of
power equipment, signal equipment and lightning protection is
connected with the integrated grounding network on the subway
platform, and can well meet the fault current (stray current)
protection requirements. Type of grounding leadout device: Type of
