Auto Tensioning Device is one of the critical component of the Overhead contact lines of the Railways.It serves both as a termination as well as provides a mechanism for the automatic tensioning of the contact lines.
Tensioning is needed on the contact lines due to the variation in the lengths of the contact lines (contact lines are primarily made from copper based alloys which are prone to expansion and contractions)due to variation in atmospheric temperatures.
Absence of tensioning would create sag or tightening of the overhead lines creating pantograph entanglement or snapping of the OHE lines.
Auto Tensioning Device/Tension Wheels/Regulating Equipment
The Winch type Regulating Equipment .
This is one of the earlier designs.This device has a mechanical advantage of 5:1 and creates a tension of 2000kgf using dead weights of 400kgs.
Three Pulley Regulating Equipment
As the name indicates this device entails the usage of three pulleys arranged in such a way so as to provide a mechanical advantage of 3:1.This device creates a pull of 2000 kgf using dead weights of 667 kgs.
Covering the length and breadth of the country our company is proud to have over 100,000 satisfactory installations of our equipments.
Section Insulator Assembly
Section Insulator Assembly or Section switches are used on the overhead lines to electrically isolate and seperate sections for maintenance reasons or at overlaps.They can also be used in conjunction to isiolate sections in seperate phases being fed by different feeder substations .They are also used extensively on changeovers.We specialize in the manufacture of the following variants.
Section Insulator Assembly for 25KV lines
This is the standard sectioning insulator which is extensively used on the major 25KV electrified network of the Indian Railways.
