• Mount the fuse cutout on a pole using galvanized brackets and stainless straps.
• Connect incoming and outgoing conductors with proper torque.
• Insert the polymer fuse tube and lock the drop-out assembly.
• Upon fault occurrence, the fuse link melts and the tube drops visibly.
• Replace the fuse link after confirming isolation.
1)The silicone rubber housing taken shape by whole injection has good hydrophobicity, drophobicity migration and soil resistance, as well as excellent electrical insulation roperties and aging resistance, which could prevent effectively those accidents of pollution flashovers so as to ensure the safe running of high voltage transmission lines.
2)The modified ECR fiberglass reinforced epoxy resin rod is used as it has good resistance to high temperature, stress corrosion &acid attack, as well as fine damping action, high tensile strength( >1200Mpa ) and resistance to creep and fatigue failure, which effectively ensure the internal insulation quality and mechanical strength of insulators.
3)End fittings are crimped onto fiberglass rod with voice-operated displacement type crimper , The insulators with this crimping technique have high mechanical strength and small dispersion.
4)The connection location between end fittings & rods is fused with sheds housing by the overall high tempera- ture vulcanized silicone rubber injection molding as it could minimize the interface.
5)The internal radial multi-seal structure effectively guarantees a long-term reliability of seal around the connection between end fittings & rods.
