YB2 Series Explosion Proof Three Phase Asynchronous Motor
1.2 YB2 series implement the standards of JB/T7565.1-2004 (YB2 series explosion-proof three-phase asynchronous motor technical qualification) and has obtained the explosion-proof certification. It consists of 15 frames ranging from 63 to 355. with a wide power range from 0.12 to 315 KVV, totally 82 specifications.
It has two types: dl and dll ,with dl applied coal mine and dll applied in factory.
1.3 Characteristics:
1).Highly standardized, unversal design. The installation size is basically the same as YB series
2).The motor has a unique design of parallel and vertical radiating slices which not only improve the radiating capability but also make the appearance more elegant
3).Insulation class: F
1.4 Working conditions:
1).Ambient temperature: -15℃≤θ≤40℃. Dl type -15℃≤θ≤35℃
2).Elevation: Belower than 1000 meters.
3).Relative humidity: Not higher than 95% for dl. Not higher than 95% for dll
4).Rated voltage: 380V, 660V, 380/660V
5). Frequency: 50HZ
6).Cooling method: IC411
7).Protection class: IP55
