Abstract
The utility model discloses a through ground wire used in a railway system, which comprises a first copper conductor positioned at the center of the ground wire, and inner and outer copper conductor layers. The inner copper conductor layer consists of six second copper conductors twisted with each other on the outer surface of the first copper conductor. The outer copper conductor layer consists of twelve third copper conductors twisted with each other on the outer surface of the inner copper conductor layer. A stainless steel sheath layer is coated on the outer surface of the outer copper conductor layer. A metal filling layer served as fillings is arranged in gaps among the stainless steel sheath layer, the outer and inner copper conductor layers and the first copper conductor. The first copper conductor, the second copper conductor and the third copper conductor are respectively formed by a plurality of copper wires inter-twisted together. The twisting direction of the second copper conductors in the inner copper conductor layer is right-hand and the twisting direction of the third copper conductors in the outer copper conductor layer is left-hand. According to the technical scheme of the utility model, the through ground wire is better in integral flexibility and bendability, while gaps among the stainless steel sheath layer and the twisted copper conductors are eliminated. Therefore, the conductor oxidation phenomenon due to water flowing into the end surface of the through ground wire is avoided. The corrosion resistance performance of the through ground wire is also improved. As a result, the service life and the safety performance of products are improved.
