Molecular Sieve Adsorbent For Gas Circuit Breaker GCB Hitachi High Power Sub Station
Product Description of Molecular Sieve Adsorbent
Due to its high chemical stability and excellent insulation performance, SF6 has been widely used internationally as an insulating medium for various electrical equipment in the 1980s. However, SF6 inevitably contains trace amounts of low fluoride sulfides during its manufacturing and use, such as SOF2, SO2F2, S2F10O, etc. These gases are highly toxic and corrosive, posing a threat to equipment operation. KDHF-03 can adsorb trace amounts of low fluoride sulfides, acidic substances, and moisture in SF6 gas. According to relevant authorities, our products have surpassed similar Japanese products in terms of the speed and depth of impurity removal.
(GIS) Gas insulated metal enclosed switchgear is widely used.
SF6 was widely used as insulating medium for various electrical equipments, due to its high chemical stability and great insulating property. But SF6 inevitably has trace amounts of low-level fluoride and water mixed in production process. Thus, with the effect of high-voltage arc, it can resolve small amounts of low-level fluoride during the run, such as SOF2, SO2F2, and S2F100, etc, all of which are highly toxic and corrosive to threat both the run of equipments and perating safety. KDHF can absorb the trace amounts of low-level fluoride in SF6, acidoid and water, etc. Identified by the relevant organizations, our products are beyond Japanese competing ones in the speed and depth of removal.

Application of Molecular Sieve Adsorbent
1100kV Gas insulated Metal Enclosed Switchgear (GIS)
SF6 Generator Circuit Breaker complete set (GCB)
Rigid gas insulated transmission line (GIL)
etc.
- Circuit breakers are vital equipment for protecting transmission systems. They cut off current instantly in the event of a system failure due to lightning or other issues./li>
- With high voltage and high current distribution systems, a Gas Circuit Breaker (GCB) that uses SF6 gas, with three times the insulating ability of air, is applied.
- This technology releases a circuit of electrodes within compressed gas, extinguishes the generated arc by blowing a stream of supersonic air, and interrupts the current.
- Hitachi is developing Gas Circuit Breakers (GCB) that work with high currents, with voltages from 100 kV to 550 kV, and accurately support increases in breaking capacity.
- For a UHV (ultra high voltage) transmission project in the United States, Hitachi delivered more than 40 800 kV GCBs (double break) through its subsidiary Hitachi T&D Solutions, Inc..
- Hitachi is developing GCBs with high-level simulation technologies in R&D, including analytical elements such as high temperature, high voltage, supersonic flow, and discharge of power.
