With the rapid development of the offshore oil industry, marine equipment has also begun to enter a stage of rapid development. Cable winches are one of the important equipment for marine scientific research, exploration, and subsea trenching operations. And slip rings are essential components of these kinds of applications.

With the rapid development of the offshore oil industry, marine equipment has also begun to enter a stage of rapid development. Cable winches are one of the important equipment for marine scientific research, exploration, and subsea trenching operations.

To answer the requirements of marine engineering related operations which are synchronously retracting and storing the umbilical cable, also being highly adaptable to the environment, there is a growing demand of high-end marine winches for high-power, ultra-high bandwidth communication and high-definition video signal transmission.

Slip ring used in offshore winches must also have high reliability and high performance to cope with the complex environment of the ocean.

Typical requirements:

l   2*50A+4* optical fiber signal

l   The protection level reaches IP65, able to endure harsh environments such as salt spray, humidity, icing and large temperature fluctuations in the marine environment

l   Anti-vibration, can resist vibration caused by hull or winch or impact load of external force

l   Power and signal transmission are stable, meeting customer’s performance demands
