Wiring column thread depth: In order to effectively avoid the phenomenon of slippery wire in the process of use, the thread depth to 15.7mm. let the connection voltage line more solid, not easy to loosen, to eliminate hidden problems. Sealing gasket: In the case of screw tightening, it can make the sealing between the product and the plate better. Tin plating process: with high chemical stability and good electrical conductivity. PA66 material: 1, has good insulation and dielectric properties, the use of safe and secure. 2, has a good heat resistance to aging, flame retardant.·Widely used in energy storage, batteries, storage cabinets, high-current machines and equipment, and other scenarios.
