Industry Risk
Fire Exposure in Wind Turbine Installations
Wind turbines operate in remote and exposed environments where fire incidents can escalate rapidly before manual intervention is possible. Critical components such as electrical cabinets, control systems, hydraulic units, braking systems and lubrication-related equipment are concentrated within enclosed technical spaces.
Because turbines are often unmanned and difficult to access, even a localized fire can result in severe equipment damage, extended downtime and costly operational disruption.
Automatic detection and suppression reduce escalation risk in critical turbine systems.
Common Ignition Sources
Typical Fire Hazards in Wind Turbines
Wind turbines combine electrical systems, hydraulic components, lubrication circuits and heat-generating mechanical parts within confined compartments. In unmanned installations, early suppression is essential to prevent major damage and extended outage.
Electrical Faults
Control cabinets, switchgear, inverters and other electrical components may generate overheating, arcing or short-circuit related fire risk.
Hydraulic Fluid Exposure
Hydraulic systems used for pitch control and braking can leak under pressure and increase ignition risk when exposed to hot surfaces.
Overheated Mechanical Components
Braking systems, generators and other rotating components may generate elevated temperatures during continuous operation.
Lubrication-Related Fire Risk
Lubricants and oil-containing systems can contribute to fire propagation when released near ignition sources.
Protega Fire Suppression Systems
Designed for Autonomous Turbine Protection
Protega designs automatic fire suppression systems for wind turbines and other critical technical installations where early detection and rapid suppression are essential.
Systems are configured to protect critical zones including:
- Electrical cabinets
- Control panels
- Hydraulic units
- Brake-related compartments
- Lubrication-related risk areas
- Other enclosed technical spaces
Upon exposure to critical temperature, the system activates automatically, without operator intervention.
How Our Systems Work
Direct and Indirect Detection Technologies
Protega fire suppression systems can be configured as direct or indirect systems depending on enclosure layout and suppression strategy.
Protega fire suppression systems can be configured as direct or indirect systems depending on compartment layout, suppression strategy and turbine design.
Protega systems primarily utilize pneumatic detection tube technology.
The heat-sensitive polymer tube is continuously pressurized and routed throughout the protected area near identified risk zones.
When exposed to flame or critical radiant heat:
- The polymer softens at the hottest point
- The tube ruptures locally
- System pressure drops immediately
- The cylinder valve opens pneumatically
- The extinguishing agent is discharged
This configuration:
- Requires no external power
- Operates autonomously
- Is highly resistant to vibration
- Is suitable for harsh vehicle environments
In a direct system, the pneumatic detection tube performs a dual function: it serves both as the fire detection element and as the discharge line for the extinguishing agent.
The heat-sensitive polymer tube is routed throughout the protected compartment near identified risk zones. The tube remains continuously pressurized (approximately 20 bar) and forms a closed detection loop within the enclosure.
When exposed to flame or critical radiant heat:
- The polymer softens at the hottest point
- The tube ruptures locally
- System pressure drops immediately
- The cylinder valve opens pneumatically
- The extinguishing agent is discharged directly through the rupture point
Because discharge occurs exactly at the highest temperature location, suppression is highly localized and immediate. This configuration provides fast response with minimal system complexity and no reliance on electrical power.
In an indirect system, the pneumatic detection tube functions solely as the fire detection element. It does not discharge the extinguishing agent.
The pressurized detection tube is routed through the protected compartment near identified risk areas. When thermal activation occurs, it pneumatically triggers the suppression cylinder without acting as the discharge line.
When exposed to flame or critical radiant heat:
- The polymer softens at the hottest point
- The tube ruptures locally
- System pressure drops immediately
- The cylinder valve opens pneumatically
- The extinguishing agent is discharged through pre-engineered nozzles
Unlike the direct configuration, the extinguishing agent is not released through the rupture point itself. Instead, it is distributed via strategically positioned discharge nozzles engineered according to enclosure geometry and airflow patterns.
This enables controlled and volumetric suppression across larger or segmented compartments.
Agent selection
Suppression Agents for Wind Turbine Applications
Agent selection is based on application-specific fire risk assessment, compartment characteristics and the type of protected equipment.
