Multifilament twisted and drawn tubular element and co-axial cable including the same

A method of making a coaxial cable, comprising:

• a) providing a core element;
• b) arranging a plurality of metal or metal alloy filaments about said core element such that said filaments are in equilibrium, said filaments and core element together forming a rope;
• and
• c) drawing said rope through at least one die to form a cable, wherein at least one of said core element and said filaments are made of a conductive material.

A method of making a cable, comprising;

• a) twisting a plurality of conductive strands about a central element to form a multifilament rope having a first diameter;
• b) drawing the multifilament rope through at least one die or swaging the multifilament rope to form a cable having a reduced second diameter;
• and
• c) removing said central element from said cable to provide said cable with a longitudinal hollow.

A tubular cable made by the process of:

• a) twisting a plurality of metal or metal alloy strands about a central element to form a multifilament rope having a first diameter;
• b) drawing the multifilament rope through at least one die to form a cable having a reduced second diameter;
• and
• c) removing said central element from said cable to provide said cable with a longitudinal hollow.
