FOAM ELECTRIC WIRE

摘要

A foam electric wire (15) according to the present invention can be used favorably in a variety of electric wire applications because it provides a high propagation velocity and a small transmission loss and minimizes the problems that result from outgassing and defoaming. Examples of applications include plenum twisted pair cables, coaxial cables for CATV, cables for HDMI, coaxial cables for antenna wires in mobile communications, coaxial cables for medical applications, coaxial cables for security, and coaxial cables for broadband applications. The above mentioned objective can be achieved with a foam electric wire (15), comprising a conductor (11) and a plurality of coating layers (12, 13, 14) that coat the conductor (11) and consist of perfluoro resin. At least one layer of the plurality of coating layers (12, 13, 14) is an unexpanded layer.
