Method for producing a lead ( 4 , I) 1 comprising an elongate conductor ( 7 ) and a helically shaped string ( 4 ) of insulator mate-rial coaxially carried by the conductor, which string has axi-ally spaced-apart winding turns, which abut against and along the conductor. The string ( 4 ) is formed of a tubular blank ( 1 ) having a greater inner diameter than the outer diameter of the conductor ( 7 ). The tubular blank ( 1 ) is cut along a helically shaped path ( 2 ) coaxial with the blank. The cut blank ( 1, 2 ) is threaded coaxially onto the conductor ( 7 ) and is axially extended. Also, the lead manufactured by the method is claimed. |
