技术问答
关于此产品的常见问题。
How is 1250A rating achieved in a tulip contact?
Through parallel finger paths. The total current divides across the finger count; spring-loaded contact pressure keeps contact resistance low on each finger. Higher current ratings (3150A and above) use more fingers and larger ring geometry.
What finger count is typical for 1250A?
Typical ranges are 16, 20, or 24 fingers depending on duty cycle and ambient conditions. For your specific application, we can recommend a finger count; provide the duty cycle and ambient temperature with your inquiry.
Can you match an existing OEM 1250A tulip contact?
If you supply the drawing or a sample. We don't claim direct interchangeability with named OEMs by reference. The drawing is the contract.
What silver plating thickness is standard?
Plating thickness varies by application and customer specification. Specify the required thickness in your order; if no spec is provided we'll quote with an industry-typical default.
What is the typical mechanical insertion cycle life?
Mechanical life depends on plating wear, spring fatigue, and insertion alignment. Specific cycle ratings are application-dependent; contact us with your duty cycle for guidance.
How do I request a sample for evaluation?
Email sales@tungarc.com with the drawing or specification and intended switchgear program.
