Underwater electrical connector is mainly used for the connection of watertight wiring trays and cables in marine operations, diving operations, mines, underwater acoustic equipment, etc., as well as the connection between electric runners and electric relays.
The existing China General Industry Standard B117?-37 General Technical Conditions for Water-saving Plugs and Sockets for Sound Exchangers> is mainly used for underwater sound projection, and is only concentrated in 0~500m underwater. The electric converter specified in this standard can be used underwater at 0~2000m. Appendix A in this standard is the appendix of the standard, and Appendix B and Appendix are the appendices of the reminder. This standard is proposed by China Shipbuilding Industry Comprehensive Technology and Economic Research Institute. This standard is under the jurisdiction of the 74th Institute of China Shipbuilding Industry Corporation. The unit of this standard is China Shipbuilding Industry Comprehensive Technology and Economic Research Institute. Shenyang Tongda Trade Display Company. The main initiators of this standard are: He Yufeng, Lin Yingde, Wang Xiaoyu, Li Qiang, Sang Chuanguo, Zhang Meiling, Wei Wei, Zhao Ruiming. 1. C/T3939—2000. Underwater electrical connectors. This standard specifies the classification, requirements, test methods, inspection rules, marking, packaging, transportation and storage of electrical connectors used underwater at depths of 2000 m to 3000 m (hereinafter referred to as "underwater electrical connectors"). This standard applies to the manufacture, inspection and acceptance of connectors used in marine exploration, hydrographic operations, underwater acoustic devices, mines, etc. 2. Reference standards. The following standards contain articles that constitute the provisions of this standard by citing them in this standard. When this standard was published, the version shown was All standards are valid, all standards will be subscribed, and the parties using this standard can choose to use the latest version of the following standards.
