Description
The G10 sleeve for bolt isolation is the chosen material for this purpose, as it is highly resistant to galvanic corrosion. It is made of high-quality fibreglass woven with epoxy resin and can withstand high temperatures. It possesses outstanding electrical and mechanical qualities, chemical resistance, low dielectric loss, and no deformation or delamination.
The main difference between NEMA grades G10 and FR4 is that FR4 is a fire-retardant grade of G10. Therefore, G10 can be replaced by FR4, while FR4 can never be replaced by G10.
Advantages
The G10 sleeve for bolt isolation has exceptional dimension stability, outstanding isolation properties, water resistance, and excellent electrical properties.
