The first electric locomotive in China was born in Zhuzhou, Hunan in 1968. It also has a resounding name: Shaoshan. It has made great contribution to the electrification of China railway.
Shaoshan series electric locomotives should be mainly used in southwest and south China with sufficient electricity. East China, where power is tight, is rare.
Compared with diesel locomotives, electric locomotives have the advantages of light weight, high power, low cost and little environmental pollution.
The following are the parameters of Shaoshan electric locomotive:

Shaoshan 4 series freight locomotive is mainly developed to meet heavy-haul freight, and its performance is better than Dongfeng 4B freight locomotive. Even comparable to Dongfeng 8 series heavy locomotive, the cumulative production of 2 12 units. Shaoshan 4 is basically designed and manufactured with reference to 6K electric locomotive imported from Japan. Except for a few unique skills, most of the advantages of 6K have been inherited, and it belongs to a locomotive with great potential.
However, such a good locomotive cannot be used without electricity in East China. Moreover, even the railway bureau with abundant electricity will have some diesel locomotives, otherwise, once the power fails, the whole railway operation will be paralyzed.

There are two Shaoshan No.4 cars in Baoding Locomotive Depot. They don't need it themselves, but rent it to others to make money. They continue to run with Lao Shaoshan themselves, which is quite economical.
Similar to Dongfeng 6 and Dongfeng 10, Shaoshan 5 is also a technical test vehicle jointly developed by China and foreign countries, and has not been mass-produced. The backbone of China Railway Department is that foreigners will never be held hostage as long as you don't have the technology and never introduce it blindly.
Shaoshan 5 passenger electric locomotive is a key scientific and technological project in the Seventh Five-Year Plan. During the "Seventh Five-Year Plan" period, China adopted the principle of combining technology and trade, and introduced foreign advanced technology while purchasing 8K locomotives of European 50Hz Group. On the basis of digestion and absorption, combined with the experience of design, manufacture and application of electric locomotives in China, Shaoshan 5 electric locomotive is designed. The construction design was completed from June 1988 to June 1989, and two sample cars were completed in September 1990 and 10 respectively. 1990 65438+February factory, and then conducted 300,000 km operation assessment in Baodi workshop in Xi 'an.

Shaoshan 7C electric locomotive is a 6-axle passenger electric locomotive, with AC DC drive of 4800kW and the highest running speed of1.20km/h. Its running condition is similar to that of Dongfeng 4D passenger locomotive, that is, "Huahu", which is stronger than Huahu, but its running speed may be slower. Because there are many bends in the southwest railway, the train doesn't need to run very fast. But it is usually overloaded, so it needs high power.

As I said before, for the fifth speed increase, the through trains are basically driven by Dongfeng 1 1G diesel locomotives, and a few are not. Eggs can't all be put in one basket, and our railway department still understands this truth.
At present, there are Beijing Railway Bureau, Shanghai Railway Bureau, Shenyang Railway Bureau and Harbin Railway Bureau on the Beijing-Shanghai line. Dozens of pairs of direct high-speed trains running on the Beijing-Harbin line are all pulled by pig heads, and there is only one direct train on the Beijing-Guangzhou line. Its tractor is Shaoshan 7E, although lonely.
With the rapid transformation of Beijing-Guangzhou Railway and Beijing-Kowloon Railway, Shaoshan 7E will proudly put into production, keeping pace with the pig head.
Shaoshan 7E electric locomotive is a six-axle trunk passenger electric locomotive with a top speed of 170km/h/h, which draws lessons from the mature technology of Shaoshan 7D electric locomotive, and the running gear adopts 2C0 bogie.

SS3 and SS6 are both passenger and cargo mixed transport models with full strength. Although they are good at climbing mountains after overloading, they can't run fast on the flat ground and have been bullied by DF-4D.
Of course, Zhuzhou people can't tolerate it, so they developed Shaoshan 8 quasi-high-speed passenger electric locomotive with low power and high speed. 1994 was put into production and was well received. Zhengzhou Railway Bureau and Guangzhou Railway Bureau, which have realized electrification, have successively purchased. At present, about 300 sets have been produced. At present, most of the express trains in the southern section of Beijing-Guangzhou line are driven by SS8, which has pushed the "Tiger" out of Beijing-Shanghai line and Longhai line. But to tell the truth, this car is ugly, not as good as "Huahu".

Pig's head is from Changzhou, and Shaoshan 7E is from Datong. As the leader of electric locomotives in China, Zhuzhou Institute will never tolerate that it cannot produce the same competitive products.
Zhuzhou people are preparing for the fifth big speed increase, and Shaoshan 9G is specially preparing for the big speed increase.
In the foreseeable years, the locomotives of China quasi-high-speed trains are basically Changzhou Dongfeng 1 1G pig heads, Datong Shaoshan 7E and Zhuzhou Shaoshan 9G.
We will wait and see what products Dalian Locomotive Works, the leading locomotive enterprise in China, will launch to continue the glory of Dongfeng 4 Series.
