A high safety level medium voltage frequency conversion cable for ships

Abstract

The application relates to a high-safety-level medium-voltage frequency conversion cable for a ship, and relates to the field of cables, which comprises a core, a filling part in abutment with the core, and a cabling wrapping layer, an inner sheath layer, an armoring layer and an outer sheath layer arranged outside the filling part and sequentially along an axial direction, the core comprising a conductor, a conductor shielding layer, an insulation layer, an insulation shielding layer and a metal shielding layer sequentially arranged along the axial direction. The medium-voltage frequency conversion cable has a long service life, meets the demand of long-term operation of the ship, has excellent radiation resistance, can resist 550 kGy of gamma ray radiation under normal working condition environment, can resist 935 kGy of gamma ray radiation under accident working condition environment, is stable in performance under nuclear radiation environment, has excellent high-temperature and high-pressure special accident environment resistance, and is stable in performance under 360 h of high-temperature and high-pressure accident environment.
