3A Zeolite Molecular Sieve Adsorbent For Sulfur Hexafluoride Gas Sf6 Protect GE ABB
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.
1. High reliability
All live parts are enclosed inside with gas as insulation medium, ensuring the reliability
2. Strong capability withstanding the environment
GIS inner live parts will not be influenced by the nature factors, such as wind, snow and rain, external pollution, high altitude etc.
3. High-quality inspection and less site work
Modernized machining devices plus complete set of quality control system, requires less site installation work.
4. Reliable conductivity performance
Self-energizing contact is adopted to ensure the electric endurance time for CB (20 operation under full-power) and 2000 operations under rated working current).
5. Less current eddy loss
Most of enclosures are made of aluminum materials (except for PT and LA), with high anti-corrosion performance and less current eddy loss.
6. Excellent enclosure structure
Cold-flanging procedure was performed for the enclosure, improving the electric field strength and reduce the size.
7. High dielectric reliability
Insulators, rod etc. shall be tested by power frequency and PD measurement, whose requirement is stricter than IEC standard.
8. CB short-circuit breaking current 63kA equipped with pneumatic, spring or hydraulic mechanism. The CB can be operated single pole or three poles.
9. New compact type with features such as low height, small size and bay distance less than2m.
10. Improvement on layout, appearance, anti-corrosion performance etc. The product has passed all type tests at KEMA inNetherlands.
11. Modular design and production. Convenient and easy for site installation and maintenance
