Indoor disconnector type OL-EL was designed to operate on the locomotive EU-07, although it is successfully used in stationary switchgears. The disconnector is designed to open and close the circuit in unloaded DC systems. In the open position it creates a visible isolating clearance.
The device has one or two poles. It can be freely reconfigured. The disconnector can be equipped with overrun earthing switch and also it can operate as a changer-over switch. Can be driven with a drive motor or manual.
The disconnector has secant construction. The base is steel structure, galvanized. On the basis there are resin insulators or glass-epoxy plates, on them there is the current path. The movable contact are moved by electrically string. The disconnector is equipped with a bimetallic silver contacts, to prevent sticking the contacts and at the same time giving a guarantee of reliability.
- simple structure
- small size
- operational reliability
- silver plated contacts
- the possibility of any configuration
