Deadend insulators provide insulation and mechanical support at terminal points where conductors end or change direction in overhead distribution systems operating at or below 69 kV. Manufactured to polymer insulator standards, they serve line terminations, angles, and tangents in suspension or deadend configurations with both bare and covered conductors.<\/p>\n

The construction combines a silicone rubber housing with a fiberglass core through injection molding and bonding. This composition delivers hydrophobic properties for wet condition performance, plus resistance to ultraviolet (UV) radiation, moisture, and chemical corrosion. The lightweight design\u2014ranging from 1.8 to 3.5 pounds\u2014and corrosion-resistant fiberglass core facilitate handling and installation while maintaining structural integrity under mechanical stress.<\/p>\n

Mechanical specifications include loads up to 70 kN with routine test loads of 35 kN and maximum torsional loads of 50 Nm. Electrical ratings span 15 kV to 69 kV, with dry flashover voltages reaching 200 kV, wet flashover voltages up to 166 kV, and critical impulse flashover ratings for transient protection. Optimized dry arc distances and leakage distances ensure reliable insulation performance.<\/p>\n

These insulators reduce maintenance requirements, minimize outages from vandalism and flashovers, and lower leakage currents for improved energy efficiency. Compliant with American National Standards Institute (ANSI) C29.13 and certified by Canadian Standards Association (CSA) and Rural Utilities Service (RUS), they meet established safety and performance standards for diverse urban, rural, and industrial applications.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>
