Frequently Asked Questions (FAQ)

1. What materials are used for the SB Series Insulator inserts?

The conventional materials used for the inserts are copper and iron. However, stainless steel and aluminum inserts can be customized based on your specific requirements.

2. Can the screw length of the insulators be customized?

Yes, while Type 2-4 screw lengths are standard (as shown in figure CLASS1-5), any non-conventional screw lengths can be fully customized.

3. What does 'BD' refer to in the specification tables?

'BD' stands for the Bore Depth of the product. The values shown in the tables represent standard bore depths, but alternative bore depth requirements can be customized.

4. Can I request a higher tightening torque for these insulators?

Yes. The tightening torque values listed in the tables are for standard installations. If your application requires greater torque capacity, we can customize the product to meet that demand.

5. What voltage standards do the nominal voltage ratings follow?

The nominal voltage ratings listed in the product tables refer to the IEC: 60355 standard. Higher voltage configurations are also available through customization.

6. What should I do if the size or height I need is not listed in the tables?

The sizes and heights listed are our conventional products. If you require other heights or dimensions, please contact our customer service team directly to inquire about customization.
