What is this standard about?
This first part of BS 3288 outlines the requirements for insulator and conductor fittings for use on overhead power lines. This includes definition of testing procedures and inspection sampling.
Who is this standard for?
- Suppliers and purchasers of overhead power line fittings
- Distribution network operators
- Consultants, inspection agencies, specifiers and overhead line contractors
- Those working on the National Grid
Why should you use this standard?
This revision outlines the most up-to-date performance and general requirements for overhead power line fittings. It covers insulator and conductor fittings such as joints, clamps and fasteners, and gives requirements on performance, corrosion protection and dimensional tolerances.
It makes users aware of testing regimes and inspection sampling, as well as giving guidance on mathematical calculations and sampling methods, including:
- Type testing
- Mechanical testing
- Tensile testing
- Electrical testing
- Deflection tests
- Thermal-cycling tests
What’s changed since the last update?
It’s been updated by technological experts to harmonize with the relevant European and international standards.
