Granite (2ES10, 3ES10)
Granite electric freight locomotive fitted with asynchronous traction motors is designed for hauling freight trains on 1,520 mm gauge railways electrified with 3 kV direct current.
Able to haul a train weighing 9,000 tons on sections with a plain track profile (up to 6 0/00) and a train weighing 6,300 tons on sections with mountainous profile (up to 10 0/00).
Booster section was designed to increase the traction properties of 2ES10 electric freight locomotives for the purpose of hauling trains of increased weight on railway sections with a particularly rough track profile.
Electric locomotives are operated on the transport network and regularly undergo warranty and after-sales service.
Years produced: 2010-2023
Advantage
The microprocessor control system of MPSU and D includes the functions of auto guidance, diagnostics, data transmission via technological radio communication channels, parameter registration, GPS/GLONASS positioning
Integrated asynchronous traction drive with axial torque control based on traction converters with IGBT transistor modules ensures high traction power
Booster section was designed for 2ES10 electric freight locomotives for the purpose of hauling trains of increased weight on railway sections with a particularly rough track profile
Use of latest energy-saving lighting technology (LEDs)
8‑10% less specific energy consumption for traction (compared to the 2ES6 electric locomotive)
Modular equipment arrangement, high reliability and maintainability
The BLOCK system ensures traffic safety
