About the Bushings and Insulators Research Facility
Traditional insulator and bushing designs using either ceramics or glass have been superseded by polymeric and composite designs, areas in which we have a lot of experience.
Our salt fog chamber is also capable of supplying mist or rain at flow and dispersion levels that meet modern test standards.
1000-hour testing of outdoor insulation systems is a common occurrence and consequently early notice of a likely test is appreciated.
In addition to the salt fog testing, we also have a controlled humidity and temperature room for conditioning samples (when required) prior to high voltage testing. We can also undertake capacitance, tan delta and partial discharge measurements to the relevant BS and IEC standards.
We also perform forensic investigation of bushings that have failed in service - for more details please see Forensics.
If you are considering a bushing test, please contact us and include the following information:
- the relevant section of a standard or details of the test schedule that you wish to have performed
- the dimensions of the bushing (preferably a design drawing)
- the required ac voltage if your test involves the salt fog chamber
- your requirements with respect to reports
