High speed railway (* * *) signal balance wire and cable DH35 through ground wire alloy sheath through ground wire

High speed railway (* * *) signal balance Wire and cable DH35 through ground wire alloy sheath through ground wire DH70 square through ground wire smooth pin Shandong Baoyulai Wire Cable Through ground wire supply

The through ground wire is a * * * signal grounding cable, and the cable core of the through ground wire 1 is a plurality of metal round wires twisted together in a layer or concentric manner, and a layer of lead sheath 2 is set outside the cable core 1. Since all equipment along the * * * line are connected to the same through ground wire, the ground potential of all signal transmission equipment along the line can be guaranteed to maintain a certain balance at any time. In addition, the ductility and flexibility of lead and copper are good, which can ensure that the through ground wire can withstand severe vibration and have a long service life in the environment with harsh working conditions for a long time, In addition, the lead sheath is used as the external protection of the through ground wire, which can play a very good role in corrosion prevention, waterproof, oxidation prevention and electrochemical corrosion prevention for the copper cable core in the through ground wire, and solve the technical problem of poor reliability of the existing grounding device of the * * signal transmission system and unbalanced grounding potential.

Through ground wire It is a main circuit of traction return In principle, it is actually a common grounding system formed by equipotential bonding *** An equipotential body of subway or light rail. Essentially equivalent to a large good conductivity . Large purple copper bar.

This product is used to return the traction power supply, power supply, signal, communication and other The electronic information system and the grounding conductors connected together by various equipment form equipotential connection to realize the functions of anti electromagnetic induction interference, static interference and anti electric intrusion of equipment along the * * * line. The models and specifications are 35 square meters and 70 square meters, and the quality has passed the inspection of * * *.

The alloy outer sheath of this product has excellent corrosion resistance and environmental protection performance, and is suitable for laying in complex soil environment in China.

1. Usage characteristics
