The thick-walled construction, combined with double annealing, ensures that the cable lugs maintain optimal and long-lasting contact pressure throughout the entire service life of the cable \u2013 with no risk of spring-back.<\/p>\n<p><strong>Key Benefits of Skyllermarks Tubular Butt Connectors:<\/strong><\/p>\n<ul>\n<li>No inspection hole \u2013 protects copper strands from
