A30 Bus Insulators

What are A30 Insulators?

Bus insulators with the A30 designation are a specialized type of electrical insulator designed for applications with high mechanical stresses. For high voltage applications where dependability and optimum uptime are crucial, A30 bus insulators are the solution.

A30 bus insulators are used by manufacturers of switchgear, power transformers, and bus ducts where a high cantilever strength is required. This is because, there are significant mechanical loads put on epoxy A30 bus insulators. The design of A30 insulators should comply with the electrical and mechanical industry standards, including IEEE, IEC, NEMA, and ANSI.

A30 bus insulators, also known as bus supports, bus bar insulators, and 30A bus insulators, don't need to be maintained. These insulators feature a distinct profile, often characterized by concentric sheds, which provide an extended surface area for enhanced insulation performance and reduced risk of electrical flashovers. Copper bus-bars can be supported by aluminum or zinc-plated steel inserts without suffering from corrosion.

Polycast A30 insulators are manufactured from high-quality composite epoxy materials, ensuring excellent mechanical strength and durability, even under harsh environmental conditions. Widely utilized in power distribution networks, A30 insulators play a critical role in maintaining system reliability and safety by isolating high-voltage conductors from supporting structures, thus preventing electrical discharge and potential damage to equipment or harm to personnel.
