Cable Trough Sealing

Additional Information

(Contact us to receive information in hardcopy form.)


In the event of a fire, oil and water may flow through the trough to other equipment causing additional damage.


SRE Solution:

Cable Trough Sealing prevents oil and water from flowing from transformer to transformer leading to additional problems.  The below picture demonstrates water leakage into the cable tray.  SRE uses materials which prevent leakage issues while allowing for future cable pulling without dam grout damage.
