Product No: LNSYJ-1
The LWMF-1 IEC 60335-1 Clause 25.15 Table 12 | IEC 62368-1 Appendix G.7.3.2.1 Table G.8 Threaded Sealing Gland Test Device is a specialized device for testing the reliability of threaded sealing gland installation in electrical products. It employs a design mode of applying torque via a fixed pulley, transmitting torque through a metal rod of specific specifications. Compared to traditional operation methods, this is more convenient and efficient, accurately simulating the actual stress conditions during sealing gland installation. The device is equipped with multiple compatible components to meet the testing needs of sealing glands of different types and sizes, including both metal and molded plastic sealing glands. It uses a two-sided chuck clamping structure, with one end fixed and the other end flexibly adjustable, ensuring the stability and coaxiality of the sample clamping and guaranteeing the accuracy of test data. By applying a standard-specified torque, this device examines the stability of the threaded sealing gland during and after installation, determining whether it meets the sealing and fixing requirements during product use, providing professional testing support for the safety performance control of electrical products.
