Outdoor disconnecting link 110 kV

Outdoor disconnecting link 110 kV

Outdoor disconnecting link 110 kV provides reliable nominal current conduction and provides interruption in current lines with frequency 50, 60 Hz with rated voltage 110 kV. Disconnecting link provides safe commutation of excitation current and line charging current. Outdoor disconnecting link 110 kV is applicable to transformer substations KTP-SESH-B (M) and indoor and outdoor distribution gears.

The disconnectors are manufactured in single-pole and three-pole versions. The design of the disconnectors, both for the main and for the earthing blades, provides for the installation of the following types of drives: PD SESH (motor), PR(M) SESH (hand). The disconnector can be fitted with both porcelain and polymer insulators. It is possible to install special protective visors. The disconnector RN-SESH-110 is certified in Rosseti PJSC.
