Cable tunnels are the lifelines of industrial, commercial, and utility infrastructure, carrying critical electrical, data, and communication cables underground or through enclosed structures. These confined spaces pose serious fire hazards due to the concentration of flammable materials like PVC insulation, dust accumulation, and potential electrical faults.

At Bhlm, we specialize in comprehensive fire protection solutions for cable tunnels, ensuring early detection, rapid suppression, and minimal disruption to essential services.

A fire in a cable tunnel can spread rapidly, producing toxic smoke and causing catastrophic failure of electrical supply, IT networks, and safety systems. Fire incidents in tunnels often go undetected until severe damage has occurred, due to limited human access and the enclosed environment.

Bhlm designs and installs smart, automated fire safety systems specifically tailored for cable tunnels, including linear heat detection, water mist systems, and clean agent suppression. These systems are engineered for unmanned areas, providing real-time detection, immediate alerting, and fast suppression—all while being compatible with critical electrical infrastructure.
