marine electrical cycle

There is no hard life cycle for marine electrical appliances. It is mainly judged based on the type, purpose, specification and maintenance of the ship. Generally speaking, the service life of electrical appliances on board ships is related to factors such as their design life, manufacturing quality, working environment, operating load, maintenance, etc. Different appliances also have different life cycles, such as:

Generator: The service life of a generator is generally 10-15 years, but it should also be evaluated based on its operating time, load conditions, maintenance, etc. The service life of the generator is also limited by ship regulations. IMO's SOLAS stipulates that the ship's emergency generator should undergo performance testing every five years.

Cables: The service life of cables is generally 20-30 years, but they must also be inspected based on their installation location, moisture, mechanical damage, insulation aging, etc. The service life of cables is also limited by ship regulations. IMO's SOLAS stipulates that fire-resistant cables on ships should be tested for fire resistance every 10 years.

Electric motor: The service life of an electric motor is generally 15-20 years, but it must also be evaluated based on its working conditions, load conditions, maintenance, etc. The service life of the motor is also limited by ship regulations. IMO's SOLAS stipulates that the ship's steering gear motor should undergo performance testing every five years.

There is no rigid service life for marine electrical appliances. It only needs to be comprehensively judged based on the type of electrical appliances, ship conditions, specification requirements, etc.
