Semi-sealed power connector series

KWT's high ampere semi-hermetic sealed integrated board connector and power bolt terminal connector. KWT is to meet the high ampere connector power input motor in large machinery and equipment. In addition to the conventional matching sintering process engineering, the magnetic metal electrical conductor poles (internal and external bolts), glass and other auxiliary insulating materials and the magnetic metal jacket matrix integrated board are combined into an integrated board through the co-sealing sintering process engineering to provide power Input channel interface end. It is also possible to combine magnetic metal electrical conductor poles, screws, and glass, ceramic and magnetic metal jacket base bolts through co-sealing sintering process engineering to form an integrated power terminal, and then according to the configuration requirements of the integrated board connector, the power terminal Single or multiple wires are directly screwed into the installation integrated board for the connection of the equipment power input motor interface.

Due to the magnetic conductivity of the high-amp magnetic metal integrated board connector, KWT caused eddy currents in the integrated wiring board connector, which caused the temperature at the wiring board to be too high and burned the equipment. It developed a non-magnetic metal semi-sealed integrated board and power bolt terminal. . In addition to the performance satisfaction of the integrated board connector, the problem of excessive temperature caused by the eddy current generated by the integrated wiring board connector and the burning of the equipment is solved, the service life of the equipment is improved, and the personal safety caused by equipment failure is reduced. To a certain extent, the motor channel interface of high-ampere power input equipment is unblocked, and it provides a safe and feasible channel interface for high-ampere input power such as large air conditioners, pumps, large coolers, large screw compressors and other equipment.
