Abstract
The utility model relates to a novel through ground wire for a railway. The novel through ground wire is characterized by comprising a copper twisted wire (1). The copper twisted wire (1) is formed by multiple copper wires which are spirally wound. Number of the copper wires in the copper twisted wire (1) is from 10 to 20. The copper twisted wire (1) is externally wrapped with a layer of external sheath (2) which is a copper sheath. The external sheath (2) is made of rare earth copper alloy seamless tubes. According to the novel through ground wire for the railway, the wire is externally provided with the external sheath so that the copper twisted wire can be protected, quality and safety of the copper twisted wire are ensured and the service life of the railway through ground wire is enhanced. Besides, the external sheath is the copper sheath which is great in conductivity, high in corrosion resistance and relatively less in contents of mercury, lead, cadmium, and chromium so that environment is not polluted after a long period of use.
Description
Technical field
The utility model relates to the novel Through ground wire of a kind of railway.
Background technology
Railway run-through ground line, on railway, for being communicated with various metallic facilities and various ground wire, guarantees that electric equipment is connected with the good of the earth, and earthing potential is consistent.Common subway Through ground wire is simple copper stranded conductor, and it can conduct electricity to discharge static.Yet railway run-through ground line is second-rate, safely, after long-term use, can produce wearing and tearing, cause the useful life of railway run-through ground line shorter.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of service quality better, high safety, the novel Through ground wire of longer railway of life-span.
The purpose of this utility model is achieved in that
The novel Through ground wire of the utility model railway, comprises copper stranded conductor, and described copper stranded conductor is that many copper cash spiral windings form, and the outside of described copper stranded conductor is coated with one deck oversheath, and described oversheath is copper sheath.
Numbers of copper lines in described copper stranded conductor is between 10 ~ 20.
Described oversheath is rare-earth copper alloy seamless pipe.
Compared with prior art, the beneficial effects of the utility model are:
This railway with novel Through ground wire at its outer setting oversheath, can play protective action to copper stranded conductor, guarantee its quality and fail safe, improved the useful life of railway run-through ground line, and oversheath is copper sheath, its good conductivity, corrosion resistance are strong, and the content of mercury, lead, cadmium, chromium is less, after long-term use, does not also pollute the environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of novel Through ground wire for the utility model railway.
Wherein: copper stranded conductor 1, oversheath 2.
Embodiment
Referring to Fig. 1, the utility model relates to the novel Through ground wire of a kind of railway, comprise copper stranded conductor 1, described copper stranded conductor 1 forms for many copper cash spiral windings, wherein the numbers of copper lines in copper stranded conductor 1 is between 10 ~ 20, the outside of described copper stranded conductor 1 is coated with one deck oversheath 2, described oversheath 2 is copper sheath, described copper sheath is rare-earth copper alloy pipe, and be seamless pipe, not only good conductivity, corrosion resistance are strong as oversheath to use seamless rare-earth copper alloy pipe, and the content of mercury, lead, cadmium, chromium is less, after long-term use, does not also pollute the environment.
Claims (3)
1. the novel Through ground wire of railway, it is characterized in that: it comprises copper stranded conductor (1), described copper stranded conductor (1) forms for many copper cash spiral windings, and the outside of described copper stranded conductor (1) is coated with one deck oversheath (2), and described oversheath (2) is copper sheath.
