Reducing high frequency fundamental coupling in polyphase cables

A method of forming a polyphase cable, the method comprising:

• manufacturing a plurality of conductor assemblies, such that each conductor assembly includes (i) a conductive conductor, (ii) a conductive phase shield arranged coaxially around the corresponding conductor, and (iii) one or more layers of semi-conductive material and one or more layers of insulating material arranged coaxially between the corresponding conductor and the corresponding phase shield;
• and
• arranging the plurality of conductor assemblies within a cable jacket, such that the phase shields are electrically coupled to each other.
