ABSTRACT
A new method of reducing the shock loads on electric transmission structures due to broken wires and other longitudinal disturbances was invented. It consists of a post spring-damper assembly, which replaces the standard suspension insulator assembly that supports the conductor. The concept was developed through finite element dynamic modeling using ADINA.
