Elinker electric Electric is a collection development, production and sales of terminal block manufacturer, product customization services. Technicians believe that the continuous use of bridge and tunnel ground terminal, building electrical terminal blocks is used only in the past greatly extends the range of applications, this new terminal all needed cables such as widely used in bridge applications. Blocks using standard are also increasingly by the users concerned, Elinker Electric bridge and tunnel ground terminal using a standard share.
1, bridge and tunnel ground terminal and connection round between used axis hole had Ying tie technology for connection Shi, first will connection round pressure into bridge tunnel type grounding Terminal Hou end not is less than 5mm, again line with Argon arc welding technology on Bridge Tunnel Type grounding Terminal and connection round between of gap for Shi welding, welding surface must around connection round a week and shall not has eye visible of gap.
2, bridge and tunnel-type ground terminal and connection between round steel fusion welding process used when connections are made, stainless steel and carbon steel the combination of two kinds of materials must be formed between atomic-scale, combined with part shall not have any small bubbles or voids.
3, bridge and tunnel ground terminal front outer diameter 30mm.
4, bridge and tunnel-type ground terminal and connect reliable bonding between the bar area shall not be less than 200mm2, but the connection technology quality control personnel could not determine otherwise.
5, bridge and tunnel ground terminal material: ≥ 16%, and Ni% Cr, Mo ≥ cent, c ≤ 2%.
6, bridge and tunnel-type ground terminal and connection between round steel-bridge and tunnel ground terminal and connection between round steel bore with interference when connecting technology, round bars onto the back of the bridge and tunnel ground terminal do not less than 5mm, weld gap may not be visible to the naked eye.
Bridge and tunnel ground terminal, including terminals, Terminal head with Terminal bar at one end connected to the neck, the other end, there is a hole, hole in wall with inner thread, post head lengths are 5-10cm, Terminal pole length for 20-50cm, Terminal pole for straight or l-shaped one. The bridge and tunnel ground terminal embedded in railway roadbed of the bridge or tunnel where you want to connect, the Terminal head up bare 3-5cm and appropriate, Terminal pole buried into the base and connect the line cord through the bolt holes in the nose. Advance when buried, according to the needs of railway subgrade using straight or l-shaped Terminal pole of this utility. By bridge and tunnel-type ground terminal and connection cable are connected, to ensure access to the full, not rusty, ensuring railway transportation safety.
