Introduction

Defining the Physical Properties of Outdoor Polymer Insulation Materials Needs Common Material and Industrial Materials Standards. This demand is there IEC /TC36 and IEC /TC15 meeting discussed and identified, including IEC /TC15 SC15E integrated into IEC /TC112. because This, in.2001 CIGRE (International Large Power Grid) D1.14 working group set up to undertake the definition of outdoor polymer insulation materials necessary physics Parameters and tasks related to the development of test methods. As a first step, CIGRE publishes a technical specification report in the 255 handbook. Determine 12 kinds of sex Can, unified one of eight kinds of performance standardization test methods and minimum requirements. For the remaining four kinds of performance, test methods and minimum requirements still need to know Indeed, this will be the next task of the D1 Working Group. The IEC Technical Report as a CIGRE Conclusion introduces outdoor polymer insulation Important material properties, their applications, standardized test methods and minimum requirements. If there is no applicable standard test method then Refer to the test methods summarized in this Guidance Document. Guidelines for the Selection of Outdoor Polymer Materials at High Voltages

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.
