AI Technical Summary
Existing technologies lack testing devices for longitudinal water resistance, and these devices are complex in structure and inconvenient to operate, which affects the testing of the waterproof performance of cross-linked polyethylene insulated power cables.
A waterproof testing device for rail transit cables, comprising a stuffing tube, end caps, support components, and transparent materials, was designed. It employs a threaded connection, sealing ring, and spring sheet structure, combined with a support base and snap-fit plate, to achieve stable cable fixation and reliable sealing. It is equipped with exhaust and water inlet pipes to control the water pressure environment, and the support components enhance the stability of the device.
It achieves efficient and accurate testing of the longitudinal water-blocking performance of cables. The device has a simple structure, is easy to operate, has reliable sealing, strong environmental adaptability, and provides accurate test results, thus improving the reliability and adaptability of the test.
