Technical FAQ – Copper Bronze Bolted Lugs

Which material should be specified?

Specify whether the bolted lug body is copper or bronze and confirm the alloy, fasteners and finish. Conductivity and corrosion resistance depend on the grade and complete design.

How do I confirm connection compatibility?

Match the conductor material, cross-section, stranding and clamping arrangement, as well as the equipment stud size and palm-hole spacing. Use only conductor combinations approved for the selected lug.

What dimensions are needed for selection?

Provide cable details, lug and palm dimensions, mounting-hole pattern and installation clearance. Confirm model-specific conductor range and fastening torque.

What determines suitability and operating limits?

Bolted lugs connect conductors mechanically to equipment or busbars. Permitted current and temperature rise depend on the complete joint; they cannot be derived from bolt size or bulk material conductivity alone.

What finish and inspection documentation should I request?

State the required surface finish, coating thickness where relevant, and critical dimensions on the order. Material certificates, dimensional reports and any specified performance tests should be agreed in the quotation. A reference to a standard is not a declaration of third-party certification.

Can I request a custom part or export quotation?

Send a drawing or clearly dimensioned sample specification, material, quantity and delivery destination. Identify application conditions and required approvals. Brass Parts India can review the requirement and confirm feasibility, price, documentation and lead time for the quoted part.
