YBT-H Series Flameproof Three-phase Marine Induction Motor for Ventilator

YBT-H the motors are designed and manufactured according to National Standard GB3836.1“Electric apparatus for explosive gas atmosphere-part 1: general requirement” and GB3836.2“Electric apparatus for explosive gas atmosphere –part2: flameproof enclosure “d”” It has the feature of high efficiency. Big rotation moment .low noise and convenient protection. The protection type of the motor is Exd II BT4, EdII CT4, It can be used on the mixture air of easy-ignition or steam and atmosphere that can be brought on explosion. This series can be matching with CBZ-II flameproof ventilating machine on board ship.
