- FLRN36-40.5D indoor AC high-voltage sulfur hexafluoride load circuit breakers, load switch-fuse combination appliances and cable-mounted load switches are designed and developed by our company by absorbing foreign advanced technologies and combining with my country’s operating requirements. The product has been fully type tested and its performance meets the requirements of GB3804 “3~63kV AC high-voltage load switch”
- GB16926 “High-voltage load switch-fuse combination appliances”, IEC60265, IEC60420 standards. The product has a “close-open-ground” three-position arc extinguishing chamber, reliable interlocking, high insulation strength of the break, large creepage distance design, and the outlet is protected by a voltage-equalizing protection cover. The cable-mounted load switch has a touchable cable front connector at the outlet, and high-voltage cables are installed on the incoming and outgoing lines, and is used in the cable branch (connection) box. The switch has a special dynamic seal and fixed seal design, which ensures reliable sealing. A pressure gauge is installed in a prominent position for monitoring during operation to ensure safe operation. It is a new generation of high-voltage switchgear equipped for urban power grids.
- Operating environment
- Altitude: The maximum altitude of the equipment installation site is 1000m;
- Ambient air temperature: upper limit +40C, lower limit -15C;
- Ambient humidity: daily average relative humidity is not more than 95%, monthly average relative humidity is not more than 90%;
Earthquake: earthquake intensity does not exceed 8 degrees; - Ambient air should not be obviously polluted by corrosive and flammable gases, water vapor, etc., and there should be no frequent severe vibrations.
- SF₆ Gas Insulation Technology Adopts SF₆ gas as arc‑quenching and insulating medium, stable performance for 40.5kV medium‑voltage power distribution network.
- Three‑position Integrated Structure Integrates close‑open‑earthing three‑position function; standard 350 mm pole spacing, fits 40.5kV ring‑main unit cabinet installation.
- Fully‑sealed Hermetic Tank Totally sealed epoxy metal tank, free‑maintenance for long‑term operation, protected against dust and moisture.
- Reliable Mechanical Interlock Complete mechanical interlock mechanism prevents mis‑operation, guarantees operator safety during commissioning and maintenance.
- Wide Application Range Suitable for 40.5kV ring‑network and radial power supply systems. Matched with current‑limiting fuse, it can replace circuit‑breaker for protection.
