Solid Core Post Insulators RIV and mechanical design are the main aspects of insulators. The RIV performance of single post insulator styles will be tested in accordance with the standard IEC60437 upon request.

Solid Core Post Insulators RIV:
The RIV performance of single post insulator styles will be tested in accordance with the standard IEC60437 upon request. If corona rings are necessary to reach a certain RIV level for a single insulator column, the appropriate ones will be offered with the insulator column.

Solid Core Post Insulators Mechanical Design:
In-service stresses on post insulators are mainly due to bending loads (e.g., weight, wind force, seismic conditions, short circuit loads). A few applications require compression strength (e.g., capacitors banks) or torsion strength (e.g., rotating disconnectors) or tensile strength (e.g., underhung post insulator).

The high strength C 130 porcelain body allows for a reduction in the number of components on insulators comprised of multiple units. The advantages provided by the reduction of additional fittings include increased arcing distance/creep and less assembly time. All insulators up to and including the C 20-1050 are available in a one-unit design.
