«Granite» (2ES10, 3ES10)
The 2ES10 freight two-section electric locomotive with asynchronous traction motors is designed for driving freight trains on 1520 mm gauge railways electrified with 3 kV direct current.
It is capable of driving a train weighing 9,000 tons on sections with a flat track profile (up to 6 0/00) and a train weighing 6,300 tons on sections with a mountain profile (up to 10 0/00).
To increase the traction properties of 2ES10 electric freight locomotives, a booster section has been developed for driving high-weight trains along railway sections with a particularly complex track profile.
Years of production: 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
A booster section of 2ES10 electric freight locomotives has been developed for driving high-mass trains along sections of railways with a particularly complex track profile
It is possible to operate an electric locomotive according to a system of many units, as well as the autonomous operation of one section of an electric locomotive
An integrated asynchronous traction drive with axial torque control based on traction converters with IGBT transistor modules allows for high traction
Reduction of specific electricity consumption by 8-10% (compared to the 2ES6 electric locomotive)
Modular arrangement of the equipment, high reliability and maintainability
The use of modern energy-saving lighting technology (LEDs)
The BLOCK system ensures traffic safety
