The Role of Grounding in Safety

Grounding serves crucial functions in protecting both people and buildings. It mitigates the risks associated with malfunctions or electrical surges from systems, whether triggered by lightning strikes or technical errors. The grounding connection operates on a simple principle: a metal wire or component creates a permanent bond with the earth. Through this connection, surges are channelled into the ground, a method known as potential equalization. Different building techniques require specific grounding inlets, and Hauff-Technik provides effective solutions for every circumstance, whether for new constructions or retroactive grounding applications.

Grounding Connections by Hauff-Technik for Every Application Scenario

Hauff-Technik provides numerous grounding connection solutions designed for a variety of application scenarios. These solutions primarily differ according to the type of construction. Hauff-Technik offers grounding connections for double and element walls, as well as flush-mounted wall installations in buildings. These connections include external sealing that complies with DIN 18533 and are suitable for structures with black basements.

The product range also features flexible grounding connections, where a steel cable establishes the link between two formwork panels, allowing for complete positioning flexibility both inside and outside the building. Moreover, Hauff-Technik's flexible grounding connections include a patented anti-twist mechanism.

These connections are intended for installation during formwork and can also be integrated in precast plants. Hauff-Technik also supplies insulated connections specifically for station construction, providing specialized cross and terminal clamps to ensure proper connection. Additional accessories such as connection bolts and lugs are included.

Hauff-Technik’s grounding connections are designed to resist corrosion and are equipped with waterproof connection threads on both ends. These threads facilitate the grounding connection, streamlining the installation process. All necessary components are included, enabling immediate potential equalization in accordance with current building standards.

For installing existing deep ground rods, Hauff-Technik offers the right solutions, such as grounding wall collars for round and flat conductors. These collars are suitable for all common types of grounding conductors and feature an integrated water barrier flange that ensures a gas- and watertight transition at the ground level. Grounding wall collars can be utilized in concrete floor slabs or walls as foundation grounding.

Optimally Implementing Retrofitted Grounding Connections

Retrofitting grounding systems in existing structures is a common task, particularly for older buildings where electrical installations often lack proper grounding. Installing a grounding connection is essential during upgrades to ensure safety and compliance.

Typically, this is done with a deep ground rod or a lateral grounding entry through the wall. Hauff-Technik offers various options specifically tailored for walls with perimeter insulation. For wall penetrations, holes with diameters of 18 to 22 mm are sufficient. Inside the building, the grounding connection is made to an electrical cable or flat/round steel, using attachment lugs with cross clamps. Hauff-Technik’s approach simplifies the process of implementing retrofitted grounding connections.
