THERMAFLOW™ THERMAL FILL
Concrete Solutions for Low Thermal Resistivity
When designing duct-bank systems, proactive risk management is key to preventing potential outage issues. Lafarge presents Thermaflow, an exclusive concrete mix with varying strengths and superior thermal resistivity levels. This advanced concrete solution is tailored to optimize duct-bank system design, ensuring predictable thermal performance and potential cost savings for your project.
The Challenge
Underground transmission lines require a stable thermal environment. Excessive heat can cause:
- derating of cable ampacity and hot spots
- reduction in cable lifespan
- premature cable failure to conduit
Backfill material selection needs to consider:
- thermal stability
- low (and accurate) thermal resistivity
- self consolidation
- precise spread, viscosity and flowability
- local availability
To Ensure Power That Never Stops:
Think Beyond Concrete
Thermaflow minimizes the depth of burial and cost of backfill and maximizes the number of conduits and size of ducts.
