Development of Electric Wire Using Biodegradable Polymer

We developed an interesting instrument in manufacturing a biodegradable polymer-insulated cable, with a variety of new functions. By using this instrument, we manufactured a poly-l-lactic acid (PLLA)-insulated cable. We measured the basic electrical insulation characteristic of the PLLA-insulated cable, and the following results were obtained. The mean breakdown strength of the PLLA-insulated electric wire was approximately 3.5-fold that of a polyvinyl chloride insulated and polyvinyl chloride sheathed flat-type cable (VVF cable). In addition, a bending test of the PLLA-insulated electric cable was performed.
