Some of the elements of your electrical facilities that CSD Sealing Systems can protect with our world leading solutions:

Substations & Convertor Stations
Sealing solutions designed for critical electrical infrastructure. Substations and converter stations form the backbone of the power grid, connecting generation, transmission and distribution systems that keep energy flowing. Any compromise to safety or integrity in these environments can lead to costly downtime, asset damage or operational failure.
Designed for electrical demands
CSD’s advanced sealing systems are engineered to protect these critical facilities from fire, water, gas, and smoke ingress. Proven across utility networks worldwide, our solutions ensure the long-term reliability and compliance of substations and converter installations, both onshore and offshore.
Applications in Substation and Converter Station facilities
- Fire-rated sealing around switchgear, transformers and control rooms
- Underground duct entries and cable basements
- Flood defence and water ingress protection for below-grade assets
- EMP and environmental protection for data and control infrastructure
- Retrofit sealing upgrades for existing substation networks

“CSD Technical Services delivered the water, and gastight sealing works to a high standard across our control room and DNO substation. Their support contributed effectively to our wider climate action plan, including the installation of a new solar farm and battery storage system. We were very satisfied with the work and will be considering CSD for future projects.”
