GB/Z 28818-2012Selection guide for polymeric materials for outdoor use under HV stress (English PDF)

1 Scope

This guideline documents the important material properties of outdoor polymeric insulation and, where applicable,

Standard test method with minimum requirements. If there is no applicable standard test method, refer to the test summarized in this technical document method.

This guideline is applicable to outdoor high-voltage polymer insulation materials for system voltages above 1000VAC and includes

Enclosures are an integral part of the device, for example in surge arresters and cable terminations. The scope of this guidance document is limited to these materials material. Insulator performance depends on several factors, such as the type of material, design, environmental conditions. Therefore, when choosing a material, satisfy the following

Column requirements are necessary, but this does not guarantee that the material will meet performance standards when used outdoors for insulation.
