TECHNICAL CHARACTERISTICS OF SUBSTATIONS TYPE «TSVPM»

Substations transformer of explosion-proof type TSVPM/6 UHL5 are designed to power three-phase current electric receivers installed in underground mines, hazardous gas (methane) and dust, аs well as for the control of active power flow, providing protection against currents leakage and overcurrent protection of low voltage lines. The level of protection and types of substations are PB 4B-3B.

Working conditions:

  • - Ambient temperature from minus 10 to plus 37˚C;
  • - Relative air humidity up to 100% at a temperature of 35±2 ˚C;
  • - Ambient dust up to 1000 mg/m3.

Dimensions and weight of substations are given in Table 1.
