Frequently Asked Questions (FAQ)

What materials are available for the SB Series Insulator inserts?

Conventional insert materials include copper and iron. However, stainless steel and aluminum inserts can be fully customized upon request.

Can I customize the screw length and height of the insulators?

Yes, type 2-4 screw lengths shown in the figure (CLASS1-5) and non-conventional screw lengths can be customized. Additionally, other height dimensions beyond the standard tables can be customized.

What does 'BD' represent in the specifications?

'BD' refers to the product's bore depth. While the values in the tables show conventional depths, we can customize the bore depth to meet your specific application requirements.

Are higher tightening torques and nominal voltages supported?

Yes, the tightening torque can be customized for greater torque demands, and nominal voltages (which comply with the IEC: 60355 standard) can be adjusted for higher voltage requirements.

How can I inquire about sizes not listed in the product tables?

For any other sizes or custom dimensions not specified in the conventional product tables, you can directly contact our customer service team by clicking the "Contact us" button.
