Abstract

Due to the unique structure of submarine power cable and its complex laying environment

its ampacity is of difficulty in study. To investigate the electro-thermal properties and the ampacity of the submarine cable

this study used three methods to analyze and calculate the ampacity of typical submarine cable. The losses of the armor and lead sheath

which are specially for submarine cable

were analyzed

and the methods for calculating the thermal coefficient and ampacity were provided. Taking the typical HJQF41 64/110 k V 1×500 submarine cable for example

its ampacity under different laying conditions and ambient temperatures was calculated. Moreover

the finite element analysis software Comsol was adopted to simulate the temperature field of the cable

and a thermal cycling test system with beach environment was designed to test the ampacity of the submarine cable. The three methods were compared in their performances

and they were demonstrated to be feasible for investigating ampacity of submarine cable.
