Brass Cable Clamp for Grounding System

The Brass Cable Clamp for Grounding System requires only standard hand tools for installation, without welding powder, molds or open flames. It is therefore suitable for photovoltaic systems, power distribution rooms, communication base stations, industrial facilities and building lightning protection projects.

Key Product Advantages

High Conductivity and Stable Contact

The brass construction provides good electrical conductivity and inherent corrosion resistance. The precision-shaped inner groove closely follows the conductor surface, while symmetrical bolts provide even clamping pressure and a larger contact area.

Flame-Free Installation

Installation can be completed with a wrench without hot work. This is especially useful in basements, distribution rooms, rooftops and other fire-restricted areas, helping reduce installation time and additional fire-control procedures.

Multiple Connection Types

Saint Ni Lightning Protection provides different structures for cable-to-rod, straight cable, cross-branch and cable-to-busbar connections. This allows contractors to select the appropriate clamp according to conductor type, size and connection layout.

Easy Maintenance

The mechanical connection can be disassembled when inspection or conductor replacement is required. For outdoor or buried connections, waterproof and anti-corrosion protection can be added according to the installation environment.

Product Comparison

For projects where open-flame work is restricted or frequent inspection and adjustment may be required, a mechanical brass connection can provide greater installation flexibility. The final connection method should be selected according to conductor material, current requirements, environmental conditions and applicable project standards.

Common Mistakes

Using the Wrong Clamp Size

A clamp that does not match the conductor diameter may result in insufficient contact area or unstable mechanical fixation. The conductor size and connection type should be confirmed before ordering.

Tightening Only One Side

Uneven tightening can cause one-sided pressure and reduce the effective contact area. For dual-bolt structures, both bolts should be tightened evenly to achieve uniform clamping.

Ignoring Environmental Protection

Although brass offers inherent corrosion resistance, outdoor buried joints and damp cable trenches may still require additional waterproof or anti-corrosion protection according to site conditions.

Mixing Incompatible Materials Without Evaluation

Different metals can have different electrochemical characteristics. When combining brass clamps with other fastening or grounding components, material compatibility and the actual installation environment should be considered before bulk installation.

Treating Every Grounding Connection the Same

Cable-to-rod, cable-to-busbar, straight cable and cross-branch connections require different clamp structures. Selecting the clamp according to the actual connection point helps improve installation reliability and simplifies future maintenance.

Typical Applications

Brass Cable Clamp for Grounding System is widely used in building lightning protection and grounding networks, photovoltaic power plants, power distribution rooms, equipment grounding, telecommunications base stations, industrial anti-static systems and selected railway or industrial auxiliary grounding applications.

It can be matched with common grounding conductors such as bare copper stranded wire, copper-clad steel, aluminum-clad steel and yellow-green grounding cables. Depending on the project layout, U-type, C-type, straight parallel, cross-branch and rod-to-cable transition configurations can be selected for different grounding connection points.

Actual Engineering Application Case

Anti-Static and Lightning Protection Retrofit Project for Industrial Park Factory Buildings

The project used 70 mm² yellow-green grounding cables with a copper-clad steel grounding grid. The installation included straight cable connections, cable-to-vertical grounding rod connections and cable-to-copper-busbar transitions.

The factory had mildly saline-alkaline soil, while welding was prohibited in the basement and electrical distribution rooms. The project also required fast installation within a limited budget.

Saint Ni Lightning Protection supplied U-type, C-type and transition clamps according to the different connection points. Outdoor buried joints were additionally protected with anti-corrosion conductive paste, and installation was completed using adjustable wrenches.

More than 1,600 grounding joints were installed. After four years of operation, annual inspections found no visible corrosion on the brass clamp bodies, while the bolts showed no stripping or oxidation. Contact resistance remained stable, and no equipment failures caused by electrostatic breakdown or lightning strikes were reported during the thunderstorm season.

FAQ

Is this clamp suitable for indoor cable shielding-layer grounding?

Yes. Brass Cable Clamp for Grounding System can be used for suitable cable shielding-layer grounding applications when the clamp size and grounding method meet the project requirements.

Does a damp cable trench require additional protection?

For damp or buried installations, waterproof and anti-corrosion protection is recommended to reduce moisture and condensation entering the connection area.

Can stainless steel bolts be used?

Yes, provided the fastening components are compatible with the clamp design and project requirements. Material selection should be confirmed before bulk procurement.

Why must both sides of the bolts be tightened evenly?

Uneven tightening can reduce the contact area and cause uneven pressure. Proper symmetrical tightening helps maintain stable electrical contact and mechanical fixation.

How do I select the correct model?

Selection should be based on conductor material, conductor diameter or cross-sectional area, connection type and installation environment. Saint Ni Lightning Protection can recommend a suitable model according to the project specifications.
