定义
An insulating base is a critical component of terminal blocks that serves as a non-conductive platform to mount conductive elements, ensuring electrical isolation between terminals and the mounting surface while providing structural stability and heat resistance in electrical distribution systems.
工作原理
The insulating base functions by creating a dielectric barrier between conductive terminals and grounded surfaces, preventing electrical leakage, short circuits, and ensuring safe voltage isolation. It mechanically supports terminal connections while withstanding thermal expansion and environmental stresses.
