Mine current collector ТР

The mine current collector ТР is designed for current collection from the d.c. contact system and current supply to electrical equipment of electric locomotives with adhesive weight of 3,4, 7, 10, 14 and 28 t., exploited in non-gas-and-dust-hazardous coal mines, as well as in workings with fresh air current of mines of the Ι and ΙΙ gas-and-dust categories pursuant to the safety rules in coal mines NPAOP 10.0-1.01-05.
The current collector is designated for work under the following conditions:
- maximum altitude above sea level – 1200 m;
- environment – explosion-proof, mining;
- dust content – up to 250 mg/m3;
- environmental temperature – minus 5 to plus 35 0С;
- vibration of attaching points within the frequency band 1 to 100 Hz with acceleration of 1g.
