3. Normal service condition of FT 16-40.5 R Series Indoor AC High Voltage Vacuum Load Switch-fuse Combinations
●altitude: no more than 1000m;
●environmental temperature: -25℃~+40℃;
●Air relative humidity: daily average value no more than 95%, monthly average value no more than 90%.
●No serious pollution in ambient atmosphere, such as dust, smog, cauterant, inflammable gas, gasoline and salts.
●seismic intensity:8°
When the service condition is different or when having special requirements, please negotiate with the manufacturer.
4. Features of FT 16-40.5 R Series Indoor AC High Voltage Vacuum Load Switch-fuse Combinations
●With separate fuse compartment, and two sides of the fuse mount with earthing switch, to ensure the safety of the maintainer when changing the fuse.
●Easy change of fuse. If it is used for wind power package substation, no necessity to stop other shunt-wound wind power unit when changing the fuse.
●When the LBS fuse’s single phase burn out, the switch will trip with the action of striker, to avoid phase-deficient operation of transformer.
●LBS has evident fracture.
●LBS has manual and motor driven operations
●LBS with compact structure and small volume, the external dimension of HXGT16 with the LBS: width 1600, depth1600, height2200.
●Perfect ‘five-protection’ function
●Cable outgoing end can connect with many cables.
●Apply unique shunt connection type vacuum arc-extinguishing device, economical and practical.
