A new method of splicing high voltage conductors has been making its way into the electrical utility industry, displacing the conventional method at an ever-increasing pace. While conventional technology uses a hydraulic compression process, this new method uses implosive energy to make the splice. This paper describes the basic principals behind this new technology and compares the implosive method with the hydraulic method. Reference is made to case examples, test results and some of the practical aspects of working with the technology.
