FAQ

Q：What key operation and maintenance precautions apply to YB2 high-voltage explosion-proof motors?

A：Certified electricians must perform all high-voltage inspections. Regularly test insulation resistance to detect aging. Protect flameproof joints from impacts and corrosion. Inspect junction box seals to prevent gas accumulation. Maintain complete grounding to eliminate static risks.

Q：What distinguishes YB2 from YBX3/YBX4 motors?

A：YB2 provides standard efficiency, while YBX3 (IE3) and YBX4 (IE4) deliver higher efficiency with reduced losses. YB2 remains widely used for equipment renovations due to comprehensive high-voltage specifications.

Q：What special insulation design handles high voltage?

A：Anti-corona insulation prevents partial discharge. Thickened stator windings use reinforced vacuum impregnation. High-voltage terminal boxes feature isolated wiring. Optional PT100 sensors monitor temperatures continuously.

Q：What is the explosion-proof rating of YB2 high voltage motors?

A: The standard markings are Ex d IIB T4 Gb and Ex d IIC T4 Gb, which conform to the GB3836 flameproof specifications for hazardous regions in Zone 1 and Zone 2.

Q: What voltage requirements are available?

A: The normal values are 3 kV, 6 kV and 10 kV at 50 Hz. The full YB2 series includes the low voltage 380V/660V.
