The electric motors of three -phase asynchronous explosion -proofs with the contact rings of the VAK series are designed to ensure operation (reduced rotation frequency) of stationary machines and mechanisms in mines, dangerous gas and dust, as well as in explosive rooms of all classes and external installations, where explosive gas mixtures may form, gases, and gases may form, vapor or dust with air, attributed by explosion to the category of LLA and groups of ignorance of T1, T2, T3, T4.
The type of climatic performance and the category of placement of engines made for the needs of the national economy and for supplying to countries with a temperate climate - U2, 5 to countries with a tropical climate - T2, 5.
The engines are designed for a long operating mode of the long S1 and the interspersonable S8 with two rotation frequencies of NOMU and 0.1NNE, from an AC network of 50 and 60 Hz at a voltage of 380/660V for engines with a capacity of 200 kW and 660V for engines with a capacity of more than 200 kW.
- Explosion protection engines - RV 3B (EXDL for export supplies).
- The degree of engine protection - IP54.
- The heating resistance class of the stator winding - F and h.
Engines have two boxes of conclusions (for the stator and for the rotor), ensuring the introduction of armored and flexible cables with copper veins with dry seal, both boxes of the findings (at the request of the customer) can turn into an angle, multiple 90.
