Grounding strands
Our earthing braids ensure reliable equipotential bonding and grounding connections in control cabinets and enclosures. They are essential for personnel safety, operational reliability, and compliance with electrotechnical standards.
Function and construction of a grounding braid
A grounding braid consists of highly flexible, often braided copper strands fitted with ferrules or lugs for secure clamped connections. It safely conducts earth-fault currents and equalizes potential between the enclosure, mounting plates, and doors to prevent touch voltages.
Applications of Earthing Braids in Control Cabinet Construction
Grounding braids are used to connect control cabinet doors, mounting plates, DIN rails, and enclosures to the ground. Particularly in environments subject to dynamic loads, they ensure long-lasting contact and prevent sparking or interference caused by electromagnetic effects.
Advantages of the Lm-therm grounding braid
Lm-therm’s earthing braids are custom-made, corrosion-resistant, and optimized for industrial use. With variable lengths, cross-sections, and mounting options, they adapt flexibly to individual control cabinet configurations and meet the highest quality standards.

Frequently Asked Questions
What are grounding wires used for in a control panel?
Grounding wires provide a flexible, low-resistance connection to ground. They reduce potential differences and help ensure the safe operation of electrical systems.
How do I select the cross-sectional area and length of a grounding wire?
The cross-sectional area depends on the current-carrying capacity and standard requirements; the length depends on the installation situation. It is important that the strand can be installed without mechanical tension.
How are grounding strands connected correctly?
Connection lugs or cable terminals are commonly used; these must be properly crimped and securely screwed in place. Ensure that contact surfaces are clean and that screw connections are appropriate.
