NEMA P1
Product Definition:
P1 is a type of phenolic paper-based material used for electrical insulation. It is made by impregnating multiple layers of paper with phenolic resin and then pressing them together under high temperature and pressure to form a rigid and durable sheet. The resulting material has good mechanical strength, high impact resistance, and excellent electrical insulation properties.
P1 is available in various thicknesses and sheet sizes. The standard thickness ranges from 0.5mm to 100mm, and the sheet sizes can be customized to fit specific application requirements.
The material is typically used for electrical insulation in low-voltage applications, such as switchboards, panel boards, and control boards. It is also commonly used for mechanical and thermal applications, such as bushings, washers, and spacers.
In terms of electrical properties, Laminates P1 has a high dielectric strength, low dielectric constant, and low dissipation factor, which makes it an ideal material for electrical insulation. It also has good thermal properties and can withstand temperatures up to 120°C without significant degradation.
Overall, P1 is a reliable and cost-effective material that is widely used for electrical insulation in low-voltage applications. It provides excellent mechanical strength and electrical insulation properties, making it a suitable choice for various industrial and commercial applications.
