技术问答
关于此产品的常见问题。
Why is CuW70 the most common grade for VI contacts?
It's the best balance of conductivity and arc erosion resistance for typical MV breaker duty. CuW75 and CuW80 trade conductivity for more arc resistance; CuW70 keeps conductivity higher while still handling the arc duty most installations see.
How does this listing differ from CuW Static / Moving / Arc Pair?
Role specificity. The static, moving, and pair listings are for contacts in specific positions in a VI. This listing is general-purpose CuW70: used when the contact's role isn't clearly static or moving, when it's a general VI component, or when CuW70 grade itself is the key spec rather than the contact role.
Can I order this in CuW75 or CuW80?
Yes. CuW75 and CuW80 are available on request even from this listing. Specify the grade in your order.
What is the typical lead time?
Lead time varies by grade, dimensions, plating, and order volume. Contact us with your specifications for a project-specific timeline.
Are silver or nickel plating options available?
Yes, on request. Plating is typically applied to non-arcing surfaces to lower contact resistance at the carrier interface.
How do I request a sample for evaluation?
Email sales@tungarc.com with the drawing or specification and intended application.
