Frequently Asked Questions

How to choose insulators for different conditions?

Selection depends on voltage level, pollution severity, altitude, mechanical load, and environmental exposure. We provide technical guidance based on IEC and ANSI standards.

Do you provide tracking and erosion test reports?

Yes, upon request, our silicone rubber materials are tested according to IEC 60587 for resistance to tracking and erosion under severe ambient conditions.

Are your insulators suitable for high-altitude installations?

Yes, we design insulators with increased creepage distance and special configurations for high-altitude applications where air density affects insulation performance.

What is the delivery time for custom orders?

Standard delivery is 4–6 weeks. For urgent or large-volume orders, we can expedite production and shipping upon request.
