KDHF-03 Molecular Sieve Adsorbent Desiccant Zeolite For Power Transmission Electricity Distribution
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.
GIS controling, measuring, protecting and transforming the electric transmission line, consists of circuit breaker, current transformer, disconnector, earthing switch, main busbar, bushing and surge arrester, etc. The interrupter of circuit breaker is designed as double-break structure, and the hydraulic operating mechanism avoids the oil leak and slow-opening at zero pressure.
With rated current of 5000A and rated short-circuit breaking current of 50kA, this kind of GIS have been adopted in Substation of 750kV power transmission project in Northwest China.
