Alkrothal 720 No.1 JRbakeng sa brake resistor
Lisebelisoa tse tloaelehileng tsa Alkrothal 720 li ka har'a li-rheostats, li-resistors tsa braking, joalo-joalo. E boetse e sebelisoa e le lisebelisoa tsa ho futhumatsa motlakase lits'ebetsong tsa indasteri.
Alkrothal 720 ke motsoako oa ferritic iron-chromium-aluminium alloy (FeCrAl alloy) bakeng sa tšebeliso ea mocheso ho fihlela ho 1000 ° C (1830 ° F).
