PURPOSE AND APPLICATION

Voltage takeoff cabinet SHON is intended for voltage takeoff from the coupling capacitors in existing and projected power transmission lines with nominal voltage 35 to 750 kV AC at fre-quency of 50 and 60 Hz, as well as for transmission of measuring data signals to automatic circuit reclosers and synchronizing devices.

SPECIFICATIONS
Main technical data and specifications meets TU 3433-005-46569277-2002 and the design documentation developed by Rosenergoservis. Small cabinets are intended for work in the weather and climatic conditions
according to GOST 15543.1-89 and GOST 15150-69 of category II (U1 and HL1).

Operating conditions:

Recommended operating temperature: -50 °C to +40 °C, operating temperature limits: -60 °C to +45 °C. SHON shall be placed at maximum height of 2000 meters above sea level, all the factors de-creasing dielectric insulation strength shall be eliminated to the maximum extent possible. The environment shall be non-explosive and free from current-conducting dust and the con-centrated aggressive vapours that destroy metal. Cabinet protection rating: IР54
