摘要： A power cable system including a power cable, and an evaporator pipe assembly extending along the power cable, wherein the evaporator pipe assembly having an inner liquid pipe including a pressurised liquid refrigerant, and an outer gas pipe arranged outside of and coaxially with the inner liquid pipe, wherein the inner liquid pipe is provided with a plurality of openings distributed along its length, and wherein the openings provide fluid communication between the inner liquid pipe and the outer gas pipe, allowing part of the pressurised liquid refrigerant to escape from the inner liquid pipe to the outer gas pipe and evaporate in the outer gas pipe, thereby cooling the power cable.
