Product Q&A

Q:What is the difference between glass and porcelain insulators?

Glass insulators offer self-breaking failure modes and superior anti-aging qualities. Porcelain insulators provide remarkable pollution resistance and robust resilience to extreme weather, making them ideal for high pollution areas and coastal zones.

Q:Do you support customized specifications?

Yes, we offer comprehensive customization including voltage grades, dimensions, creepage distance, hardware fittings, and anti-fouling levels. We provide OEM and ODM services for power grid, railway, and industrial applications.

Q:What is the warranty period and quality standard?

Products are manufactured in strict conformance with international IEC standards. We offer an enduring quality warranty with an exceptional service life of over 20 years under standard operational conditions.

Q:What is the production and delivery capacity?

Peak season lead time is within 15 workdays, and off-season lead time is also within 15 workdays. We ensure rapid production advancements and global distribution capabilities.

Q:Do you provide after-sales service and technical support overseas?

Yes, we provide professional services worldwide, including expert guidance on product selection, technical parameter verification, installation advice, and thorough after-sales support to ensure smooth experiences.
