CONSTRUCTION:

External Disconnectors RLNR 20/400-UHL1 are intended for activation and disconnection under voltage of the sections of the electrical circuit with a voltage of 10-20 kV in the absence of load current, or for modification of the connection scheme, as well as earthing of disconnected areas by means of fixed earthworms, if any.

RLNR 20/400-UHL1 symbols:

• R is the disconnector
• L – linear
• N – external installation
• R – chopping type
• 20 – rated voltage, kV
• 400 – nominal current, A
• UHL – climate performance according to GOST 15150-69
• 1 – accommodation category according to GOST 15543.1-89

CONDITIONS OF OPERATION:

• Maximum wind pressure – 1000 Pa (40 m/s wind speed)
