CURRENT COLLECTOR HEAD
The current collector head, attached to the top of the pole by means of its sleeve, consists of the following components:
- main body, made of aluminum alloy, integrates a sleeve, a bore for the vertical pivot bushing, a bolt to connect litz wire with the power cable and a mounted protecting shield,
- vertical and horizontal stainless steel pivots including their self-lubricating bushings,
- carbon holder, made of a special bronze alloy that due to its good sliding properties reduces contact line wear,
- carbon insert of length 102 mm, slightly conical in its longitudinal as well as its transverse sections, which enables exchanging without using any tools,
- copper litz wire bridges over the pivots in order to avoid their extensive electric corrosion,
- arcing horn which prevents the carbon holder from burnloss if the head rebounds or ice accretions accumulates on the lines,
- grease nipple to lubricate the vertical pivot.
