New Implosive Connector Technology for High Voltage Conductors
نویسنده
چکیده
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.

The authors have investigated factors that contribute to overheating of connectors installed in medium voltage joints. Tests completed on connectors for 1/0 AWG and 750 kcmil conductors confirm that the currently used test for evaluating connectors for use in joints is insufficient. Furthermore, the Success Criteria for these tests cannot be modified to better align the results with connector p...
