Electric motors and generators are a common set of machine components that convert mechanical and electrical energy into each other. During the transmission and conduction process of electrical energy, cable glands are important components when connecting cables, which undertake the key task of transmitting power or signals. In order to ensure the reliability and safety of cable glands, various countries and organizations have developed a series of standards to regulate the design, manufacturing, and installation of cable glands.
There are generally international electrical engineering standard(IEC), national standard(SAC), industry standard, material standard and safety standard(NEMA). Following these standards can ensure the reliability, safety, and durability of cable glands, reduce potential risks and increase the service life of equipment.
