Dielectric Properties of HFO-1336mzz(E)/N₂ Mixture as a Possible SF₆-Substitute Gas

Characteristics of perfluoromethyl vinyl ether: A new eco‐friendly alternative gas for SF6

“…In recent years, exploring eco-friendly insulating gas to replace the most potent greenhouse gas sulphur hexafluoride (SF 6 ) for new-generation gas-insulated equipment (GIE) has consistently garnered significant attention worldwide. Researchers have successively proposed various candidates such as perfluoroisobutyronitrile (C 4 F 7 N) [1][2][3], heptafluoroisopropyl trifluoromethyl ketone (C 5 F 10 O) [4][5][6], trans-1,3,3,3-tetrafluoropropene (HFO1234ze(E)) [7][8][9], trans-1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336mzz(E)) [10][11][12], etc. and systematically investigated the insulation, arc extinguishing, stability/decomposition, material compatibility, and biosafety.…”

Thermodynamic, transport, and radiation properties of HFO-1336mzz(E) mixtures as eco-friendly SF6 alternatives

“…Kothe et al tested the insulation strength of several new fluorides through lightning impulse test and found that the mixture of HFO-1336mzz(E) with CO 2 /N 2 has excellent insulation performance similar to C 4 F 7 N/CO 2 and C 5 F 10 O/CO 2 [10]. Tang et al conducted DC breakdown experiment on HFO-1336mzz(E)/N 2 mixture [11], measured the critical breakdown field strength of HFO-1336mzz(E) mixed with CO 2 and dry air through the Pulse Townsend experiment and inferred that they have potential for application in medium voltage (MV) power equipment [12]. Zhang et al carried out breakdown tests of HFO-1336mzz(E) mixtures and found that the insulation strength of 30% HFO-1336mzz(E)/CO 2 and 30% HFO-1336mzz(E)/Air at 0.12 MPa are equivalent to that of SF 6 at 0.1 MPa [13].…”
