Developed a submarine cable laying operation for the use of optical cable laying equipment,
Special motors that can withstand sea pressures up to 4,000 meters.
The product is required to work well even when withstanding the huge water pressure at a depth of 4,000 meters
The motor is made with a special oil-filled structure, a special production process and advanced testing methods, which is enough to withstand the water pressure at the deep sea
A special motor that is indispensable for laying submarine communication fiber optic cables in various seas around the world
Since the laying of submarine fiber optic cables between Dover in United Kingdom and Calais in France in 1850, submarine fiber optic cable laying work has been carried out in various seas around the world. Whether it is the development of wireless or the emergence of satellite communication, the quality of communication and the size of communication capacity make submarine fiber optic cable the protagonist of contemporary communication, connecting countries around the world. Submarine fiber optic cable laying ships equipped with special equipment for fiber optic cable laying are mainly used in submarine fiber optic cable laying operations. When laying, the sediment on the seabed is washed away, and then the cable is buried in the cable trench to prevent the cable from being washed away by ocean currents. The optical cable laying equipment is equipped with a birdcage induced AC motor for deep-sea developed and produced by Japan Denco KINETEK Co., Ltd. Deep-sea AC motors have a special structure and are filled with oil. Unlike air, oil is not affected by external pressure in that its volume is sufficient to withstand water pressure at a depth of 4,000 meters.
The inside of the motor is filled with a special structure that resists pressure oil in the deep sea and is resistant to high pressure
In order to ensure the function and performance of the motor, special processing technology is adopted in all aspects of production and testing
On the other hand, since the inside is filled with oil, the rotor is resisted by the oil as it rotates, and the rotational speed decreases. In order not to reduce the rotational speed due to the resistance of the oil, we have improved the shape of the rotor. In addition, the manufacturing process adopts a special manufacturing method unique to deep-sea motors. For example, the stator is made by centrifugal casting and has a delicate structure with no internal gas defects. In addition, vacuum and pressure impregnation is used to prevent voids when coiling copper wire into the stator. Before shipment, a series of rigorous tests such as heat resistance test, torque, speed, current and voltage test with brake load applied, overvoltage and devoltage test, and leakage test are carried out. The tests were carried out in a simulated tank that simulates all the effects of the electric motor in a deep-sea environment, and the data can be recorded and interpreted by a computer. As a result, a comprehensive quality assurance system has been established to ensure that it can fully perform its functions at a depth of 4,000 meters.
In the production process, centrifugal casting method, pressure reduction/pressure resin impregnation method and other processing technologies are used to ensure the sealing of the inside of the motor
