Optimised Insulator Design Part 1 – Enhancing Pollution Performance
Speaker 1: Hello. Together today we are talking about optimising insulator designs.
One of the benefits of insulator customisation is the ability to adapt the insulator design
to meet specific environmental conditions.
This is very valuable to utilities in certain geographical regions where there are high levels of contamination.
By adapting the shed profile according to the pollution grade and and environmental conditions,
the performance of the insulator is optimised, reducing maintenance requirements and overall cost of ownership.
An example of this is the customisation of the insulators in the Netherlands to counteract high
levels of saltwater fog in the environment.
By using a steep shed design, a better protected creepage distance is created and the accumulation of water is avoided.
This modification significantly increases the performance and reduces the risk of flashover.
Another good example of long rod customisation is the open shed profile, also known as the desert shed.
This design is used commonly in Kuwait to create a barrier against pollution build up due to extended dry seasons.
Station posts can also be adapted to meet specific leakage requirements.
to optimise the insulator performance in coastal areas, regions with high contamination levels
and also specific HVDC applications.
Feel free to reach out if you have a particular environmental challenge that you think might
be helped by optimising the shed profile of your insulators.

Background
When it comes to transmission line insulation, there’s no one-size-fits-all solution. However, by considering optimised insulator design, engineers can tailor their grid insulators to match environmental conditions, delivering greater performance and efficiency.
In Part 1 of our 2-part video series on Optimised Insulator Design, ITG Expert Contributor Christoph Purucker considers the performance, maintenance and cost advantages of customising insulators to maximise their performance in challenging environments.
Looking at real-world examples, Christoph explores how utilities are tailoring designs to specific pollution types, such as salt fog or desert dust, to boost reliability, reduce maintenance, and lower long-term costs.
