Which standards govern overhead line fittings?
Internationally, overhead-line fittings are commonly designed and tested against IEC publications and the purchasing utility's own specifications, which define mechanical ratings, dimensions, test methods and acceptance. In practice each utility standardises on a set of fitting types and drawings, so the governing document for a project is usually the utility's own standard sheet. Silverstone Electric produces fittings to applicable IEC/utility specifications — send your standard or drawing and conformity is confirmed line by line.

Frequently asked
Do you hold certificates to a specific fitting standard?
Send the standard number and clause set you need; conformity is confirmed item by item rather than claimed in blanket fashion.
Can you work to our national standard?
Yes — quotation against your standard's drawings and ratings is the normal route.
What about insulators and cutouts?
Insulators, cutouts and arresters follow their own IEC families; see the product catalog for the applicable ranges.
