Waterproof Nickel Plated Brass EMC Shielded Cable Gland With EMC Spring
The use of tetrafluoro gaskets can reduce friction between rubber and metal surfaces and improve service life.Spring shielding layer is adopted, the contact surface of bottle blank is large and the installation efficiency is high.The inner rubber is made of silica gel, which can meet the normal work of the product in extremely cold weather. The product realizes the contact sealing between clamping ring and cable surface, which has little damage to cable and can effectively prevent the internal of motor or controller.
Cable joint is an indispensable part of cable line. It can realize the connection of two cables and improve the electric field at the end of two cables.The cable joint in the middle part of the cable line is called the intermediate joint, while the cable joint at the two ends of the line is called the terminal head.In order to reduce the inductive electromotive force of metal sheath, shielded cable joints are needed to realize cross transposition connection in order to eliminate the circulating current generated by inductive electromotive force.
Metal shielding and grounding treatment
The function of metal shield in cable and joint is mainly used to transmit short-circuit current of cable fault and electromagnetic interference of shielding electromagnetic field to nearby communication equipment. In operation, metal shield is at zero potential under good grounding state. When cable fault occurs, it has the ability to transmit short-circuit current in a very short time. The grounding wire should be welded reliably. The metal shield and armor band on the body of the box cables at both ends should be welded firmly. The grounding of the terminal should be reliable.
