cylinder cartmobilefor distribution switchgear

Filling of gas : 0 - 10 bar Evacuation of air : < 1 mbar DILO couplings : DN8/DN20 Operating voltage : 220 - 240 V Frequency : 50 - 60 Hz Operation : manual Standard version • vacuum pump for evacuation of air (16 m³/h [at 50 Hz]; 19m³/h [at 60 Hz]), final vacuum 1 mbar • pressure reducer for SF6 • SF6 cylinder connection W 21.8 x 1/14" • gauge 0 to -1,200 mbar • primary gauge NG63, class 1.6, 0 - 60 bar • secondary gauge NG100, class 1.0, 0 - 10 bar • indication units in bar, ps, kPa • ball valve DN8 with hand wheel • 6 m long wire-braided hose DN8 • DILO couplings DN8 and DN20 • 3 m long electrical connecting cable • solid tyre wheels • paint: orange For evacuation of air and safe refilling of SF6 into gas compartments by overpressure This device covers two important functions: The integrated vacuum pump allows the evacuation of air down to < 1 mbar so that no air/gas mixture is produced during the subsequent filling process. The use of gastight and selfclosing DILO couplings guarantees emission-free gas handling. The weight of the gas to be refilled can be conveniently registered (with the 3-001-4-R022 / R122 version) by means of the integrated weighing scales. The weight is indicated on the illuminated display which switches off automatically if the scales are not used for a longer period of time. Thanks to the tare function, the gas can be precisely quantified. Advantages & functions • frame • hose reel • couplings can be exchanged without any gas loss • most common global cylinder connections available as accessories
