A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
A grounding clamp establishes a secure, low-resistance electrical connection between a grounding conductor and a grounding electrode or other grounded object, ensuring safe dissipation of fault currents and static electricity to earth.
Common materials include copper, bronze, galvanized steel, and stainless steel. Each offers different conductivity and corrosion resistance properties, and the choice depends on the application environment.
Check the rated current, contact resistance, conductor range, clamping force, operating temperature, ingress protection, material, surface treatment, tensile strength, and weight against your requirements. Always confirm these values with the manufacturer for the specific model.
Relevant standards include IEC 60947-1 for rated current and contact resistance, IEC 60068-2-1 for temperature, IEC 60529 for ingress protection, ASTM B16 for material and tensile strength, and ISO 2093 for surface treatment. These are reference standards for verification, not proof of certification.
