OUR PRODUCTS

Power Connectors

We do proper selection of materials to ensure adequate Mechanical Strength, Corrosion Resistance and optimum Electrical Efficiency. Connectors are made of Aluminium Alloy Grades as per BSEN 1676 - 2020 and Fasteners - S.S. to BSEN 3506-1-2020 & HDG Class 8.8.

In case of Aluminium Copper joints, Bimetallic Sheets of Aluminium-Copper are used to prevent Galvanic Corrosion. Fasteners used are made of Stainless Steel / HD Galvanized M.S. We provide the grade as per standard / customer requirements.
