SOME COMMON RAW MATERIALS THAT ARE USED FOR SWITCHGEAR APPLICATION COMPONENTS
Silicone bonded Muscovite Mica is an Alumino-silicate. It has exceptional physical, electrical, mechanical and thermal characteristics. Primarily, Mica M is used in the area of high voltage and high temperature electrical insulation.
Commercial Grade Vulcanized Fibre is a proven performer that possesses good physical and electrical properties. It is often used for its superior arc quenching capability. However, its unique combination of mechanical and electrical properties make it suitable for a wide range of applications.
PolyPro FR® is a flame retardant polypropylene that carries a UL 94 V-0 flame class rating. This material exhibits excellent formability characteristics. As a result, it can be quickly formed into three-dimensional shapes. This material is known to be the economical choice for electrical insulation applications.
Grade N155 is a Class F glass mat reinforced polyester material. It is designed for applications where excellent compressive and flexural strength are combined with high temperature resistance.
GPO-3 offers excellent track, arc and flame resistance. In addition to that, it also provides good mechanical and thermal performance. The low smoke generation and flame spread characteristics of this material are what make it a highly preferred choice for transit applications.
NEMA Grade G-9 is a woven glass cloth reinforced laminate with a melamine resin binder. The glass melamine insulating materials offer high mechanical strength. Therefore, this G-9 material is going to provide excellent flame arc resistance.
Sheet Molding Compound (SMC)
SMC is a high strength polymeric composite material. It has strong mechanical and electrical insulating properties that make it ideal for supporting bus bars or other live electrical components.
Polycarbonate is utilized for its strong mechanical properties and good electrical insulation characteristics. This material is commonly used for sight windows or finger guards in metal enclosed switchgear equipment, as well as for glazing and machine guards where the need for high impact resistance is required.
The NEMA Grade FR4 material consists of glass fabric reinforced laminates that are bonded with flame resistant epoxy resin. This material has the ability to maintain excellent mechanical, electrical and physical properties, specifically at an elevated temperature to 130° C.
The RM & RMR materials consist of 100% pure cotton rag paper and electrical grade polyester film. They are laminated with a carefully selected adhesive system and are available in two or three ply combinations.
Bulk Molding Compound (BMC)
BMC is a polymeric composite material that contains strong mechanical and electrical insulating properties, making it an ideal choice for supporting bus bars or other live electrical components.
