Disconnectors are intended for closing and opening dead sections of alive electrical circuits as well as for earthing disconnected sections with the help of earthing switches. Disconnectors are used also for switching off idle current of transformers and charging currents of overhead power lines.
Advantages
• all conductive circuit terminals are coated with galvanic tin and silver, and detachable terminals are made of plastic silver with mechanical lifetime of 10,000 CO cycles;
• 30 mm sleet-proof;
• resist the wind speed of up to 40 m/s when there is no sleet, and not more than 15 m/s in the case of 20 mm sleet;
• terminal lead is symmetric about the insulator axis, which allows connecting both flexible and rigid busbars without using adaptors;
• feature a reliable fixing in C position against throw forces of short circuit currents;
• easy-to-operate due to the fact that all friction units are fitted with maintenance-free bearing units with lubed-for-life closed ball bearings and hinge joints;
• all parts of disconnectors have durable corrosion-resistant hot-dip galvanized coating;
• fitting dimensions of disconnectors series RDZ fully match the dimensions of the replaced series RG;
• possible to supply disconnectors on supporting steel structure;
• supplied with support brackets for installation of drives.
