Description
Overhead power lines need insulation that is light, tough, and recyclable, and the standard material fails on the last two counts. Xindong Zhao and co-authors rebuild the recipe around polypropylene, filling it with hollow glass microspheres to cut weight and a rubbery copolymer called SEBS to restore toughness. The standard, cross-linked polyethylene, cannot be recycled and its density makes cables sag.
The glass spheres cut density by fifteen percent, from 0.890 to 0.757 grams per cubic centimeter, but left the material weak. Adding SEBS fixed that: tensile strength more than doubled, and stretch at break leapt from 72 to 671 percent. Electrical tests stayed strong, with breakdown strength near 109 kilovolts per millimeter and very low dielectric loss. The authors conclude the blend achieves light weight without giving up insulation quality, suiting it to overhead lines.
