Secure Covers for Drip Pans in Power Plants and Substations
Graepel fire-resistant gratings are the safe solution for covering transformer drip pans. The fire-rated surface structure combines high drainage capacity with a flame-retardant effect.
In the event of an emergency, fire-resistant gratings perform two key functions:
- Rapid drainage of transformer oil into the containment pan
- Flame-retardant effect through targeted reduction of oxygen supply
The specially tested, perforated surface structure allows only a minimal flow of oxygen to the source of the fire. This results in an extremely oxygen-deprived fire, while escaping oil can simultaneously drain unimpeded and quickly.

Technical Design and Engineering
Graepel manufactures fire-resistant gratings as ready-to-install grating panels or as individual panels. This enables quick installation and maintenance. Graepel provides support right from the planning stage and creates project-specific installation plans. The gratings can be adapted to different load requirements and designed to suit the specific substructure.
Graepel offers two certified embossed patterns:
