SLiM (sagging line mitigator) - mitigating excess sag in overhead transmission lines

Line-to-ground clearance often dictates line-loading limits (ampacity). Excessive sag from high conductor temperature operations, caused by line loading and ambient conditions, is often the limiting condition. Previously, expensive line reconstruction., tower raising or reconductoring was the only true solution to this problem. The SLiM-sagging line mitigator was developed as a cost-effective and easier alternative. The SLiM is a new class of transmission line hardware that fixes this problem in real time. In response to high conductor temperatures, SLiM uses state-of-the-art materials and a fully tested concept to decrease the effective length of conductor in the span. This mitigates the thermal expansion experienced by the conductor and reduces or eliminates excess sag
