Railway Contact Wire Manufacturer

The Overhead Line Equipment includes the suspended wires over the railway lines to supply electricity. Among them, one important wire is a contact wire. It is the main component of the system providing electricity via the pantograph of the locomotive.

The contact wire used in the railway is solid and hard-drawn grooved electrolytic. It could have a cross-sectional area of 107 sq. mm, 150 sq. mm, or 193 sq. mm. Basically, a high tensile strength combination of metals like Cu-Sn, Cu-Ag, and Cu-Mg is used for its manufacturing. Mostly a copper magnesium alloy is used for the same purpose.

Choosing a good railway contact wire manufacturer depends on the availability, reliability, and durability of contact wires. All these criteria should be met before choosing the manufacturer. Also, the wires should be able to tolerate weather conditions like high rainfall, extreme temperatures, and pollution.

They can be made to go through various tests to find the best railway contact wire manufacturer. Some of the tests to check the contact wires are as follows-

1.      Examine the railway contact wires visually.

2.      Measure the weight as well as the diameter of the railway contact wires.

3.      Measure the lay ratio as well as the lay length of the contact wires.

4.      The electrical resistance should also be measured of the railway contact wires.

5.      Measure the tensile strength of the contact wires as well.

Apart from these tests, the success of contact wires also depends on the efficiency of their interaction with mechanical devices. Also, only a legally insured manufacturer should be hired to avoid any miss-happenings.

Railways act as a major mode of transportation in most areas. A major proportion of the working population also prefers railways and metros to commute daily. A failure in a single wire could lead to hampering of work of several people. This makes it highly necessary to ensure top-quality railway services.
