Abstract

A nickel-copper through earth wire comprises a stranded conductor twisted by a plurality of single conducting wires, each single conducting wire consists of a nickel layer and a copper wire coated by the nickel layer, and the stranded conductor can be pressed tightly after twisting. Another structure includes that a plurality of stranded conductors form a compound stranded conductor via compound standing after each stranded conductor is twisted. The nickel-copper through earth wire has fine conductive performance, corrosion, abrasion and high temperature resistance and long service life, avoids problems of cracking and the like, and is free of toxic and harmful substances or environmental pollution.

Description

The ambrose alloy Through ground wire

Technical field

The utility model relates to a kind of earth cable, in particular for the earth cable of railway signal system as Through ground wire.

Background technology

The Through ground wire of existing railway signal system, its structure mainly contains two kinds: a kind of is Through ground wire at twisted copper conductors peripheral hardware conductive plastic jacket; Another kind is the Through ground wire at the metallic sheath of twisted copper conductors peripheral hardware lead or aluminium or its alloy.The former is in long-term use, and phenomenons such as wearing out appears in conductive plastic jacket easily, cracking cause conductor oxidation, electric conductivity to descend, and influence is normally used; Latter's poor corrosion resistance, long-term use easily is corroded, and can not normally use, and also can pollute environment.

Summary of the invention

In order to overcome the deficiency of the Through ground wire that has railway signal system now, the utility model provides a kind of ambrose alloy Through ground wire.

A kind of ambrose alloy Through ground wire that the utility model provides comprises the bundle strand conductor that is twisted into by several conduction single lines, and every conduction single line is made of the nickel dam coated copper wire.

For the gap between the conduction single line of the present utility model is reduced, the rounding more that seems can will be restrainted the strand conductor and compress behind stranded bunchy strand conductor.

The another kind of ambrose alloy Through ground wire that the utility model provides comprises the bundle strand conductor that is twisted into by several conduction single lines, and every conduction single line is made of the nickel dam coated copper wire, and several bundle strand conductors twist the formation multiple stranded conductor again.

The beneficial effects of the utility model are: both possessed excellent conducting performance, had corrosion-resistant, wear-resisting, resistant to elevated temperatures advantage again, also do not had problems of crack, long service life; There is not poisonous and harmful substance in the product, environmentally safe.

Description of drawings

Fig. 1 is the cross sectional representation of a kind of structure of the present utility model; Fig. 2 is the cross sectional representation of another kind of structure of the present utility model.

In Fig. 1, Fig. 2,1, the conduction single line, 2, copper wire, 3, nickel dam, 4, bundle strand conductor, 5, multiple stranded conductor.

Embodiment

With reference to Fig. 1, adopt plating or chemical plating process plating nickel dam 3 outside copper wire 2 to make conduction single line 1, the bundle strand conductor 4 with conduction single line 1 is twisted into also can twist conductor 4 with bundle and compress, promptly is a kind of execution mode of the present utility model.

With reference to Fig. 2, employing is electroplated or chemical plating process plating nickel dam 3 outside copper wire 2 is made conduction single line 1, and the bundle strand conductor 4 with conduction single line 1 is twisted into twists conductors 4 multiple strands to several bundles again and constitutes multiple stranded conductors 5, promptly is second kind of execution mode of the present utility model.

Claims

1. an ambrose alloy Through ground wire comprises the bundle strand conductor that is twisted into by several conduction single lines, it is characterized in that every conduction single line is made of the nickel dam coated copper wire.

2. an ambrose alloy Through ground wire comprises the bundle strand conductor that is twisted into by several conduction single lines, it is characterized in that every conduction single line is made of the nickel dam coated copper wire, and several bundle strand conductors twist the formation multiple stranded conductor again.
