New Aquaria's revolutionary arrester core design combines extremely high mechanical strength and stiffness along with good electrical insulation properties, high heat resistance, plus outstanding ease of processing. This polyamide alloy gives good mechanical strength & electrical insulation properties as compared to the conventional glass fibre wrapped design, which are hazardous by its nature of procesing. This internal structure is fully encapsulated in a robust and non-tracking material which provides the required flashover resistance for the application.
