Reliable mounting quality to install lightning protection with confidence

DEHN’s Maxi MV clamp revolutionizes the way lightning protection systems are installed. This innovative clamp eliminates the need for welding, offering faster, safer, and more environmentally friendly installation. Whether you’re safeguarding a critical industrial site, a military facility, or a nuclear power plant, the Maxi MV clamp ensures consistent quality and peace of mind.

Lightning: A force to be reckoned with

Lightning strikes are unpredictable and devastating, releasing transient voltages that can cause fires, equipment failures, and structural damage. External lightning protection systems are your first line of defense, channeling the immense electrical energy safely away from your building and the people inside.

The Maxi MV clamp from DEHN plays a vital role in these systems, securing components like conductors and grounding rods with precision and reliability. This parallel clamp is designed with a tear-off screw for precise and reliable mounting. By simplifying the installation process and ensuring consistent quality, it enhances the overall effectiveness of your external lightning protection, helping your systems withstand even the most powerful storms.

Key features of the Maxi MV clamp

DEHN’s Maxi MV clamp is an advanced mounting solution specifically engineered for the rigorous demands of external lightning protection systems. Combining precision, durability, and simplicity, it sets a new standard in secure and reliable installations.

Tear-off screw technology

At the core of the Maxi MV Clamp’s design is its innovative tear-off screw. During installation, the screw is tightened with a standard wrench, and once the precise clamping force of 35 +/- 2 Nm is reached, the head automatically shears off. This ensures a consistent and secure connection every time, removing the fluctuations associated with traditional methods.

Corrosion-resistant materials

The Maxi MV Clamp is constructed from high-quality, corrosion-resistant materials, making it ideal for industrial environments, nuclear facilities, and outdoor installations. Its robust design provides long-term reliability, even in the harshest conditions.

Proven industrial performance

The Maxi MV Clamp has been rigorously tested and proven in some of the most demanding applications, including military installations and nuclear power plants. Its dependable performance and ease of use make it an essential component for modern lightning protection systems.

The Maxi MV Clamp transforms the way lightning protection systems are installed, ensuring high-quality results with minimal effort.

Welding vs. Maxi MV clamp: A clear comparison

Traditional methods like exothermic welding have long been the standard for mounting lightning protection and other rooftop or external building systems. However, the Maxi MV clamp offers significant advantages that redefine what’s possible for these installations.

Advantages of the Maxi MV clamp

The Maxi MV clamp delivers exceptional benefits that outshine traditional welding methods, including:

  • Time savings: Welding requires an average of 16 minutes per connection, compared to the Maxi MV clamp’s quick 30-second installation time. This dramatic reduction speeds up projects and minimizes labor costs.
  • Consistent quality: The Maxi MV clamp features a tear-off screw and a defined tightening torque system that ensures precise clamping force every time, eliminating guesswork and reducing the risk of errors.
  • No special equipment required: Unlike welding, which demands specialized tools and expertise, the Maxi MV clamp installs with a standard wrench, simplifying the process.
  • Environmentally friendly: Welding produces harmful fumes and poses environmental risks, while the Maxi MV clamp offers a clean and sustainable alternative.
  • Weather-resistant: Welding operations are weather-dependent and challenging in adverse conditions, but the Maxi MV clamp can be installed even in rain, ensuring project timelines stay on track.
  • Safety first: The Maxi MV clamp eliminates risks associated with welding, such as burns, fumes, and sparks, creating a safer working environment for installers.

The limitations of welding

While welding creates a permanent bond, it comes with inherent challenges that can slow down projects and increase risks:

  • Lengthy installation times: Each weld requires meticulous preparation, execution, and cooling, consuming valuable time.
  • Specialized expertise: Welding demands highly skilled workers and specialized equipment, increasing costs and complexity.
  • Environmental and safety risks: Harmful fumes, sparks, and the risk of burns make welding hazardous for both installers and the surrounding environment.
  • Weather restrictions: Welding is highly sensitive to environmental conditions and cannot be performed in rain or high humidity.

The Maxi MV clamp is a transformative solution that simplifies installation, enhances safety, and delivers consistent results—all while cutting down on project costs and timelines.
