Due to the large tonnage for the ocean surveillance ship, it need to install a large generator set. The conductive slip ring is used in the electromechanical system like generator system which need to transmit current or data signal to continuous rotation. It is installed in the crane slewing center, used to transfer power and signals when it up and down.
The main purpose of increasing the distance between the motor collector slip rings is to prevent the sudden lift of the unit that leading to short circuit between the upper and lower slip ring, reducing the ablation probability of collector slip ring torus.
This type slip ring used for marine surveillance ship is not only required stable performance, long life, maintenance free, but also should be fully satisfied the special requirements for military equipment in different application areas, such as high protection class, high and low temperature resistance (-60 ~+200), shock resistance, high voltage resistance, low electrical noise, isolation greater than 60dB, low loss .etc.
