The moving transformer

---

Rail net­works world­wide are usu­al­ly oper­at­ed with 15 or 25 kilo­volts of
alter­nat­ing cur­rent. Depend­ing on the trans­former, these are con­vert­ed into an appro­pri­ate out­put volt­age that sup­plies the elec­tric motor, which gets the wheels turn­ing.

100 — 150 °C
is the oper­at­ing tem­per­a­ture.
Flame-retar­dant esters are there­fore used as insu­lat­ing agents.

< 25 HERTZ
The trans­form­ers are oper­at­ed at a much low­er fre­quen­cy than pow­er trans­form­ers (50/60 Hz).

2.5 — 4.5 METRIC TONS
due to the trans­former. They have to be com­pact and light so that the loco­mo­tive isn’t too heavy.

30 YEARS
The trans­former is in use for at least this long, and trav­els approx­i­mate­ly 600,000 rail kilo­me­ters per year.
