<p>PURPOSE:To enable the generation of an unbalanced compressive force distribution to be extremely reduced, by contriving the profile of the steel sleeve of a compression type wire extending clamp to be similar to the shape of the internal surface of compression dies for compressing the steel sleeve. CONSTITUTION:Before a steel sleeve 11 is pressure-fitted on an electric wire 1 like an optical fiber composite aerial earth wire, then the profile of the steel sleeve 11 is formed to be similar to the shape of the internal surface of compression dies 20. In its case, if needed, a slit may be formed longitudinally in the steel sleeve 11. Before the steel sleeve 11 is pressure-fitted on, first an aluminum sleeve 12 fitted outside the steel sleeve 11 by the compression dies 20 is compressively deformed, and after that, the sleeve 12 is compressed further, and the steel sleeve 11 is contrived to be pressure-fitted on. As a result, a device can be designed so as not to apply bad influence upon internal electric compression.</p> |
