With over 20 years of collaboration with leading experts in ventilation, our solutions are trusted across a wide range of tunnel and underground applications —including Fire rated on load switch disconnection and cabling systems —ensuring reliable performance and enhanced safety in complex environments.
Smart systems for tunnel projects
We specialise in creating and manufacturing customised solutions for the electrical control and protection of ventilation, smoke extraction and power line connections in tunnel environments. Our systems meet the highest standards of electrical safety with special focus on the performance against overload and short circuit conditions. Designed for reliability and resilience, our smart systems ensure operational continuity and safety in complex underground infrastructures, adapting to the specific needs of each project.
Engineering for underground safety
Our engineering team develops solutions specifically designed for tunnel environments, where fire conditions and electrical hazards demand exceptional resilience. We design systems to perform reliably under both normal and abnormal scenarios, including controlled performance during fire events. Backed by a highly qualified team, our R&D process integrates rigorous internal factory testing and validation, complemented certified external assessments when required. This approach allows our products meet the highest safety standards and deliver dependable performance in underground infrastructure.
Built for harsh conditions
We have the skills to provide innovative and high-quality products that can cope with applications with the most demanding conditions of temperature, humidity, fire and other environmental factors. Our products are built to withstand severe environments such as extreme temperatures, pressurized water, floods, UV rays, corrosive substances, saline environments, impact hazards, etc. We also offer connection adaptions for power circuits and auxiliary circuits with section reductions, bimetallic connections, EMC shielding, signaling elements and airflow elements.
Certified for global markets
Our products are tested and certified to meet the most demanding international standards for electrical safety and fire resistance. Fire performance is validated under EN 12101-3, with classifications in F300, F400, and F600—where we stand out as the only provider offering certified F600 performance. Electrical safety is ensured through compliance with IEC/EN 60947-3 and UL 508 / CSA 22.2 this guarantees global reliability and trust in critical underground applications.
Gave will exhibit our solutions for tunnel safety at AFTES 2026
From October 12 to 14, 2026, Gave will take part as an exhibitor at AFTES 2026, a key international event focused on underground engineering and tunnel infrastructure, bringing together leading experts, companies, and professionals from across the sector.
At this edition, Gave will showcase its advanced safety solutions for tunnel applications, designed to ensure safe, reliable operation in demanding underground environments.
Visit us at stand P8, it will be an excellent opportunity to know about our solutions first‑hand, exchange perspectives, and continue driving innovation in the underground infrastructure sector.
¡We look forward to meeting you in Lille!
