Product Overview
The disconnecting switch is made up of base, pillar insulators, contacts, wiring board and other parts. The pillar insulators and the store -to-store score are installed on the base, and the intersection angle of the two pillar insulators is 50°. The base is fixed on a bracket inclined 25 ° . A shaft connected with the operating mechanism is installed on the bracket. It can be equipped with CS17-G manual operation mechanism or CJ6 motor mechanism .
Product feature
The disconnecting switch adopts the double- post center-opening and the contact turning-in structure, which has the ability of self- cleaning contacts and improves the contact reliability.The rotating par t of the disconnecting switch i s designed to be maintenance-free. The revolving seat is designed as a sealed structure, and moisture, dust, and harmful gases cannot enter, so that the bearing and the aluminum disulfide lithium-based grease will always work in a self-contained environment. The bearing bearing will not rust, the grease will not be lost, and the mining will not dry. The operating torque after long-term operation of the disconnecting switch will not increase. The stainless steel shaft pin and the oil- free self-lubricating bearing are matched with hot- dip galvanized steel parts to ensure that the disconnecting switch is flexible, portable, reliable and never rusty.
