常见问题

What is the primary function of an insulating spacer in core clamping systems?

To provide reliable electrical isolation between metal clamping components while maintaining structural integrity under mechanical pressure and thermal cycling.

How do I select the right insulating spacer material?

Consider operating voltage, temperature range, mechanical load, environmental conditions, and compliance requirements. FR-4 is common for general applications, while polyimide offers higher temperature resistance.

What are common failure modes of insulating spacers?

Dielectric breakdown from contamination or moisture, mechanical cracking under excessive pressure, thermal degradation, and tracking/erosion from partial discharges.
