Scope of this standard specification standard composite insulator
is higher than the nominal voltage 1000 v ac overhead line with the definition of composite insulator, test methods and acceptance criteria.
This standard is applicable to line trailer or Zhang Fuge resistant insulator, composite insulator accidentally also may be limited by the compression or bending load, such as when used as insulator phase interval, mainly by bending load.
Line post insulator does not belong to the scope of this standard.
The composite insulator has involved this standard & other;
Mandrel & throughout;
And & other
Umbrella cover & throughout;
Mandrel is usually made from glass fiber after immersion resin.
Umbrella cover can be made of a variety of materials, including elastomer (
Such as silicone rubber, ethylene propylene rubber)
For example, alicyclic resin)
Or for fluorocarbon compounds (
Such as teflon)
This standard does not include the relevant according to the specific operating conditions to choose the requirements of high voltage insulator.
The terms of the normative reference files of the following files by reference in this standard, constitute provisions of this standard.
Every note date reference documents, its all subsequent modification single (
Not including errata content)
Or revised edition are not applicable to this standard, however, according to the agreement of the parties of this standard are encouraged to study whether can use the * new version of the file, anyone who doesn't note date reference documents, its * new version is applicable to this standard.
