钨铜梅花触头

When the contact sees arc exposure during insertion or break, not just continuous current. Standard tulips handle plug-and-unplug at MV current well; they don't handle arcs. If your application opens or closes under load, CuW tips are worth the cost.

Yes, that's the standard construction. Brazing is done in-house with copper-silver fillers under controlled atmosphere. Full-CuW fingers (no copper body) are available but uncommon, heavier and more expensive without performance benefit for most duty cycles.

Tip length depends on duty cycle. For occasional fault current breaking, a short tip is enough. For repeated load switching with arcs, a longer tip extends service life. Specify your operating cycles and expected arc current with your inquiry.

Yes by default. The plating reduces contact resistance at the mating stud interface; the CuW tip stays bare to handle arc duty.

The CuW Contact Finger is for single-finger applications (sliding contact, disconnector finger). This SKU is for multi-finger plug-in tulip assemblies. The tip-vs-body construction principle is the same.
