The Formed Wire Dead End is a helical wire component that terminates and secures Optical Ground Wire (OPGW) and All-Dielectric Self-Supporting (ADSS) cables in overhead transmission and distribution systems. It provides a mechanical endpoint handling axial and compressive loads as an alternative to bolted dead-ends.<\/p>\n

The design features a wrap-on installation requiring no specialized tools, reducing labor time and complexity. An integrated Current Transfer Tab eliminates separate grounding clamps, lowering material and handling costs. Inner Structural Reinforcing Rods protect the cable from excessive bending strain and distribute loads uniformly to minimize damage to the core and optical fibers. The tab, captured between the OPGW and rods, provides direct electrical connection with fault current ratings from 80 to 150 kA\u00b2\/sec.<\/p>\n

Constructed from corrosion-resistant aluminum clad steel or galvanized steel, the component matches conductor types to prevent electrochemical corrosion. Specifications include diameters from 0.51 to 0.54 inches, lengths up to 48 inches, and holding capacity of 60% to 95% of cable rated breaking strength with component strengths reaching 6500 pounds. Performance validation includes 100 million aeolian vibration cycles and compliance with Institute of Electrical and Electronics Engineers (IEEE) 1138 and IEEE 1591.1 standards.<\/p>\n

Primary applications involve OPGW and ADSS cables at line or elevation angle changes exceeding 30 degrees. The dead end can be specified for right or left lay directions to match cable construction, ensuring compatibility across power and telecommunication infrastructure installations.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>
