Transmission Line Tools Suspension Insulator , Porcelain Insulator
High-voltage line anti-fouling disc-shaped suspension porcelain insulators are generally assembled into insulator strings for power lines of different voltage levels and different pollution areas. It is used in industrial dust, chemical, saline, alkali, coastal and foggy areas for insulation and fixed wires on high-voltage overhead transmission and distribution lines.
Stain-resistant insulators are divided according to their umbrella structure:
Model | Rated electromechanical failure load kn | Tension load by tension kN | Crushing load N.cm | power frequency withstand voltage kv | Lightning shocks dry withstand voltage kv | Power frequency breakdown voltage | radio interference voltage | Weight kg | ||
Dry | Wet | Test voltage to ground kv | 1MHZ max radio interference voltage Μv | |||||||
