What is BS EN IEC 60305 about?
BS EN IEC 60305 applies to string insulator units of the cap and pin type with insulating parts of ceramic material or glass, intended for AC overhead lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It also applies to insulators of similar designs used in substations.
BS EN IEC 60305 applies to string insulator units of the cap and pin type either with ball or socket couplings or with clevis and tongue couplings.
BS EN IEC 60305 describes specified values for the mechanical characteristics and for the main dimensions of string insulator units of the cap and pin type.
Note: For the definition of site pollution severity see IEC TS 60815-1.
Who is BS EN IEC 60305 for?
BS EN IEC 60305 on insulators for overhead lines is relevant to:
- Manufacturers of string insulator units
- Electrical engineers
- Companies involved with power transmission and distribution lines
- Industries working with high-voltage transmission lines
Why should you use BS EN IEC 60305?
BS EN IEC 60305 covers mechanical characteristics, dimensions and types of string insulator units of the cap and pin type. The characteristics include:
- Specified electromechanical or mechanical failing load (SFL)
- Maximum nominal diameter of the insulating part
- Nominal spacing
- Minimum nominal creepage distance
- Standard coupling
The corresponding values for these are provided in BS EN IEC 60305.
If you are a manufacturer, compliance with standardised parameters for string insulators of the cap and pin type can impart a high degree of consistency and uniformity in your production processes. This can further enhance credibility and reliability for your products and the end-use application.
