ESTWELD® RAILWAY SIGNALING BOND

Railway Electrical Protection

The consequences of an unexpected lightning strike or power surge can be catastrophic for a facility:
Risk to personnel
Critical equipment may be damaged, or destroyed Data can be corrupted The costs of operational
downtime and lost revenue can be very substantial

As the railway industry becomes more dependent on increasingly sensitive equipment,proper protection from lightning and dangerous over-voltage transients is necessary.
After a long period of research，testing and
product development, ESTWELD® has acknowledged that no single technology can totally eliminate vulnerability to lightning and power surges.

Connections to the Rail

ESTWELD® is a molecular bond which-when properly applied-cannot loosen,resists corrosion and produces a maintenance-free electrical connection.
Railway signaling is a system used to control traffic safely.essentially to prevent trains from colliding.
Exothermic welding is one of the most popular methods of railway signaling bond.In welding process,the mastensite is formed by rapid cooling,quenching,of autensite which traps carbon atoms that do not have enough time to diffuse out of the the ctystal structure.When viewed in cross- section,the lenticular(lens-shaped) crystal grains appear acicular(needle-shaped) crystal grains appear acicular (needle-shaped).Martensite affect to the rail with increasing risk of cracking and brittle.
