Construction
Polymeric insulator is injection molded from grey track resistant high-density polyethylene. The insulator is designed with a specialized mechanism for securing the cable using a pair of compression jaws with a calibrated clamping force holding mechanism.
Features
• Dielectrically compatible with Southwire polyethylene covered conductors or other polyethylene covered conductors
• Insulator is molded from grey track resistant polyethylene compound
• UV resistant
• Lightweight and shatter resistant
• Special clamp with torque calibrated holding bolts
• Available for both covered and bare conductors
Application
The Polymer Vise-Top Insulator is used in 15kV overhead distribution lines with bare or covered conductors. The insulator was developed to meet the electrical, mechanical and environmental parameters typical of overhead distribution lines.
Nylon inserts are used for covered conductors and metallic inserts are used for bare conductors.
