How Cable Makes the Subway Move?

Like the dragon, the subway strides forward with numerous people's hope.

The maximum passenger volume of the subway can be up to tens of thousands of people with the length of several tens of meters; the subway has become the main force of the city transportation system with its speed of over 100 km/h.

According to the name, the subway is rapid transit systems are electric railways that are operated through the ground tunnels. How does this "underground dragon" operate rapidly?

Coal usage? No, that's one hundred years ago. The world's first subway system was the partially underground Metropolitan Railway which opened as a conventional railway in 1863 with the tractive power of the steam locomotive.

How to "electrify"? Like electric bike and electric vehicle?

This is not the common "electrify process;" common power supply modes are "third rail" and the distribution system.

Main Substation obtains high pressure (110 kV or 220 kV) from the urban area power grid that reduces the voltage; the medium voltage becomes the power source of the power supply system and the distribution system.

Now let's discover the "hidden expert" of the cable industry.

Cable for rail transit is the "real hero." They are the "hidden project" laid at hidden places but carries the essential role of connecting the entire power transmission system. So we call it is "hidden in the city."

How Important is the Cable Rail Transit?

The minimum construction cost of 1km metro system is seven hundred million for early investment consideration. Under normal circumstances, the construction period of one metro line is from four to eight years.

There are many factors to consider to excavate an underground tunnel including the shifts of the pipeline system of the city (rain, sewage, tap water, thermal power, electric power, communication and street lamp) that requires some collaborations among multi-department.

More than that, problems to overcome during the construction include the environment and the complex landscape.

Looks like the subway the "group star" of the transportation system.

The maximum daily passage volume of the metro of the first-tier city can reach more than six million that reduces the transportation pressure of the city greatly.

As an essential transporting role of the subway system, the cable for rail transit is the "forage" of the safe operation system. "Food and forage should go ahead of troops and horses," the high reliability of cable is the foundation of the safe operation of the subway system.

To fulfil the market demand, the DC Feedback Cable for Rail Transit with Rated Voltage of 1500V and below developed by Far East has great safety and reliability that is authorized to reach the advanced level in China. The "hardness" of the cable prevents infestation, rat bites and ultraviolet. The excellent water-proof property could avoid external damage and lower the level of fire hazard that provides a better choice for the city railway system.

Well, this is not enough. Far East continues to perfect its products and services in the belief of “the ultimate products and service.” Technical engineers of Far East investigate the construction condition on-site to make the appropriate layout plan. Meanwhile, they never stopped improving the product design based on the project needs, and guarding the safety of every metro line.

Far East has been participating in the metro service for many cities including Beijing, Xi'an, Nanjing, Wuxi, Wuhan and Hohhot, and will always be the safeguard of our daily travel.
