21 Advantages of Using MICAFLUID Technology in 2021

Efficient degassing with the single-stage vacuum. MICAFLUII3 plants require only the smallest suction capacity from the vacuum pumps as the operating pressure for effective degassing is between 1 mbar – 9 mbar. Optimised electric heating system with horizontal configuration. The oil is indirectly heated and automatically regulated to within 1°C of the setpoint while ensuring a thermal flux of< l W / cm², which prevents hot spot cracking of the oil and guarantees its integrity. The complete system is vacuum tight. The entire system is vacuum leak-tested with a guaranteed leakage rate of< 0.025 mbar • l / s, eliminating any entry of air into the process. Variable flow-through. Due to an oil level control system, espe­cially developed by MICAFLUID, the oil flow is automatically adjusted to the flow-throughput setpoint without the risk of flooding.

21 Advantages of using MICAFLUID technology in 2021

Furthermore, due to an array of technical features which guarantee effective vacuum tight treatment without the risk of microbubbles or contamination, MICAFLUID systems ensure process integrity without any compromises to the asset whether in a production line or substation. 21 Advantages of using MICAFLUID technology in 2021Get price

Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, gaz sf6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in sf6 gas gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what insulating gas can do in centimeters.Get price

Measuring partial discharge in GIS - Think Grid

To overcome this constraint, a parallel technology was developed, the Gas-Insulated Substation (GIS), using a gas, for example sulphur hexafluoride (SF 6), at high pressure. SF 6 has excellent dielectric properties and is used as the insulating medium between the phases and between the phases and earth. As a consequence, a GIS is much more compact.Get price
