The busbar insulators of the P series are cylindrical in the main body and designed with a hexagonal prism shape at the lower end. They are basically applied in low-voltage environments, with a rated voltage of approximately 600-2500V. Due to the hexagonal prism design at the lower end, a clamping wrench can be used to accurately set the torque. During the assembly process, the installation torque can be better controlled. The general installation torque is between 1-3NM. This product is widely used in circuit boards, so there is a higher demand for precision.
