Description

Are intended for the power supply of the electric receivers installed in the underground openings dangerous in gas (methane) and powered coal with the three-phase current as well as for the protection against the leakage current and maximum current protection of the lowvoltage lines. Level and type of the implosion protection is PB-4B-3B-a (Exdial) according to GOST 12.2.020-76. Protection category ensured by the casings is JP54 according to GOST 14245-96. Running gear is fitted with the wheel pairs of the tubs for 600 or 900mm gauge.
