TE Connectivity:<br />
Fully electromagnetically powered system<br />
An improved generation of electrical solutions for railway use has<br />
been developed by TE Connectivity, eliminating the previous disadvantages<br />
of standard mechanical pneumatic master switches. The innovative<br />
VESA vacuum master switch for electric trains, for<br />
example, is claimed by its manufacturer to be the first fully<br />
electromagnetically operated system for 25 and 15 kilovolt<br />
vehicles. The VESA VCB (Vacuum Circuit Breaker) provides<br />
impressive proof of what is now possible, according<br />
to this exhibitor. The highest levels of reliability have been<br />
demonstrated on more than 800 units on four continents.<br />
The performance features of the VESA VCB are designed<br />
for high speed and regional trains, metro systems and locomotives<br />
all over the world and have proved their effectiveness<br />
even under extreme weather and climatic conditions.<br />
The lightweight in its category, the VCB weighs less than<br />
half as much as conventional pneumatically operated master switches<br />
and also requires less maintenance than they do. Another significant<br />
advantage of the VESA system is its low energy consumption.<br />

Automatic crack detection with t C rack<br />
What is surely the world’s most unusual crack detection system,<br />
tCrack, has been deployed for the first time in the Gotthard base tunnel<br />
in Switzerland. The work of collecting data in the tunnel, and its<br />
subsequent evaluation, were successfully completed during the first<br />
quarter of 2012. Operating in the world’s<br />
longest tunnel, the system automatically<br />
identified, classified and fully documented<br />
cracks with a predefined tolerance limit.<br />
With tCrack the company has developed<br />
a new, advanced and economical<br />
measurement system that satisfies all the<br />
customer’s requirements with regard to the<br />
quality of data, as well as the speed and reliability<br />
with which it is collected, this Swiss<br />
exhibitor reports. This outstanding kinematic<br />
system provides high definition digital<br />
images, which are combined with extremely precise and absolute<br />
positional data. The automatic crack identification and optimised<br />
formwork provided by tCrack offers substantial financial, qualitative<br />
and technical advantages for all those involved in a tunnel project.<br />
