Additional Information

(Contact us to receive information in hardcopy form.)


Oil filled equipment has potential to leak putting nearby equipment at risk.


SRE Solution:
Transformer Cable Drop Penetration Seals
prevent oil from entering the conduit and damaging adjacent equipment.  The conduit fire stop also provides a seal against damaging contaminates such as dirt, yard stone, and water.  Seals also provide UV protection.







SRE Advantages:

  • Ability to adjust cables and easily reinstall the designed fire protection system
  • Before and after matrix aid in proper system selection.  Also provides visual to compare completed work insuring correct installation. 
  • Design drawings are assembled allowing each step of the process is able to be understood by a novice installer.  Following each step in sequence insures a fire protection installation that will function in a fire/smoke event.
  • Ability for corrective maintenance to be performed 10, 20, even 30 years from now
  • System designs are installed by SRE’s trained and certified installers.
  • Ability to install while the unit is live.
  • Materials can withstand UV light.
  • Protects against oil leakage, water, animals, etc. from using the openings to access the building’s cable space
