Product Highlights

Copper Profile Conductors

Upper conductive circuit employs high-conductivity copper profiles, delivering excellent electrical conductivity, high mechanical strength, and superior corrosion resistance.

Graphite Silver-Plating Technology

Contact fingers utilize graphite silver-plating at engagement zones. Self-cleaning and self-lubricating properties achieve maintenance-free operation while enhancing contact reliability.

Main-Ground Linkage

Grounding switch interlocked with disconnector ensures simple and reliable operation.

Monobloc Base Frame

Support base fabricated from bent steel plate to withstand electromagnetic forces and mechanical stresses caused by line terminal faults or short-time currents.
