The British Rail Class 92 is a dual-voltage electric locomotive, which can run on 25 kV AC from overhead wires or 750 V DC from a third rail. It was designed specifically to operate services through the Channel Tunnel between Great Britain and France.
The Series 92 engines were introduced in 1974. [8] Compared to the Series 71 engines they were derived from, the Series 92 featured a larger bore of 4.84025 ± 0.00125 in (122.942 ± 0.032 mm) and an identical stroke of 5 in (130 mm) for a nominal displacement per cylinder of 92 cu in (1,510 cc), from which the Series 92 derives its name.
Although it bears the name of K Series, the engine has almost no components in common with the 4-cylinder version. In its Rover setup, the unit delivers peak engine power of 175 PS (129 kW; 173 hp) at 6,500 rpm, and maximum torque of 240 N⋅m (177 lb⋅ft) at 4000 rpm.
The Red Army adopted the V-2 engine in the same year in three modifications: the V-2 (500 hp (370 kW)), the V-2K (600 hp (450 kW)) for the KV line of tanks and the V-2V (375 hp (280 kW)). [ 1 ] Near the end of the 20th century, the V-2 was fitted with more modern modifications by the chief designer of the head design bureau for the Chelyabinsk ...
If two devices share the same type designation other than the first letter (e.g. ECL82, PCL82, UCL82) they will usually be identical except for heater specifications; however there are exceptions, particularly with output types (for example, both the PL84 and UL84 differ significantly from the EL84 in certain major characteristics, although ...
KV-85 (Object 239) – A KV-1S with the 85 mm D-5T cannon in a new turret, with the ball mounted hull machine gun repositioned to the right of driver (now fixed mount) and the hole welded shut; 148 of these tanks were produced in the second half of 1943 until the spring of 1944 as a stopgap until the IS tank series entered production.
IEC 62067 Power cables with extruded insulation and their accessories for rated voltages above 150 kV (U m = 170 kV) up to 500 kV (U m = 550 kV) – Test methods and requirements IEC 62068 Electrical insulating materials and systems – General method of evaluation of electrical endurance under repetitive voltage impulses
The Class 395 can operate at a maximum speed of 140 mph (225 km/h) under 25 kV AC overhead electrification on High Speed 1, and 100 mph (160 km/h) on 750 V DC third-rail supply on conventional lines. It is typically formed as a six-car train, although they can be rapidly coupled to one another to form a 12-car train as required.
