技术问答
关于此产品的常见问题。
Do all vacuum interrupters need CuW guide pins?
No. Most use steel or hard aluminum pins. CuW pins are specified only when the pin sits close enough to the contact gap that arc exposure matters. For new designs, evaluate whether arc exposure is real before specifying CuW. It's often not necessary.
What grades are available?
CuW70, CuW75, and CuW80. CuW70 is typical for guide pins; higher tungsten content is rarely needed since the pin doesn't see direct arc duty.
Can pins be supplied with threaded ends?
Yes. Threading, chamfers, flanges, and other end features are routine per drawing.
What tolerance can you achieve on diameter and straightness?
General machining tolerance per drawing. Tight tolerances on straightness for long pins may require post-machining straightening; specify in your order.
What is the typical lead time?
Lead time varies by grade, dimensions, features, and order volume. Contact us with your spec for a project-specific timeline.
