It is possible to change out splices in power lines while the line is energized. The procedure also improves the reliability of the splice. A splice is usually pressed together using hydraulics while the line is down (see result in figure 1, left image). But a company names Quanta replaces and redesigns the splice using implosion to enhance the quality and replace the old splice on-the-run. The high quality result can be seen in figure 1 on the right.
