Designed to withstand the harshest environmental conditions and high pollution levels. The base of the Disconnector and all non - current carrying metal parts are made by formed hot dip galvanized steel.
The insulators are manufactured of high-quality brown porcelain. The Disconnector’s contacts, terminals and blade are made of tin-plated copper.
The contacts are self-cleaning and always maintain constant pressure and once secured in the closed position can withstand seismic, wind and other vibration forces without opening.
The hook is made of hot dip galvanized steel. All screws, nuts and washers are made of hot – dip galvanized steel to ensure long and trouble-free operation.
The operation of the Disconnector is done manually using a hookstick. The Disconnector can be mounted on a steel structure, vertically or at 300 .
