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 (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, bore depth requirements can be customized to meet specific needs.
Are higher tightening torques and nominal voltages supported?
Yes, 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.
What industry standard applies to the nominal voltage values?
The nominal voltage specified in our tables strictly adheres to the IEC: 60355 standard, ensuring safe and reliable operation in electrical systems.
How are final product dimensions and colors verified?
Actual performance parameters, dimensional tolerances, and appearance colors are subject to specific technical drawings confirmed prior to manufacturing.
