Major projects Once the tallest building in Shanghai, the Far East helped to build!

At present, supertall buildings, as landmarks of the city, have become a symbol of
urban modernization.
However, it is undeniable that it is not easy to build a super high-rise building, because its nature determines the high cost, complex function, coupled with a large number of people, so the requirements for safety and security are extremely high, far exceeding the general high-rise building
。 Taking the Shanghai World Financial Center as an example, as early as 2008, as a landmark building in Shanghai at that time, it became the tallest building in Shanghai with a height of 492 meters, and was named "Best High-rise Building of the Year" by the World Society of Tall Buildings and Urban Habitat, and ten years later, in 2018, it also won the "'Ten-year Special Award' of the 16th Global Tall Building Award" issued by the World Society of Tall Buildings and Urban Habitat
.

The cable laying of this super high-rise building puts forward quite high requirements for the quality of the cable and the laying scheme, and even is harsh
.
In the face of challenges, Far East Cable Co.
, Ltd.
, a subsidiary of Far East Smart Energy Co.
, Ltd.
(hereinafter referred to as Far East Stock Code: 600869), has independently developed hanging cables and spreaders for super high-rise buildings through continuous research and innovation, which have been successfully applied to the Shanghai World Financial Center, breaking the monopoly of foreign technology and realizing completely independent research and development, design, production and delivery
.
Up to now, it has been operating safely for 13 years, and has become the best witness
of the quality of cables in super high-rise buildings of Far East Cable.

Construction is difficult and there are technical gaps

As the "blood vessel" of the building, cables will continuously supply blood to the building's electrical heart, so its safety and stability are crucial
.
Especially for a super high-rise building such as the Shanghai World Financial Center, its importance is self-evident, and once the cable fails, it will cause unimaginable serious consequences
.

Compared with general high-rise buildings, super high-rise buildings have higher
requirements for electrical design.
For example, the narrow vertical shaft space of cable installation and laying makes it difficult to lay and install, coupled with the heavy weight of the cable itself, it is easy to be strained in long-distance vertical laying, so that long-term safety cannot be guaranteed, which has become a pain point
in cable design and construction.
At the same time, the technology of lifting cables for super high-rise buildings is still in the hands of Japanese companies, and there is a technical gap
in the domestic cable industry in the field of lifting cables.
At that time, the investor Japan's Mori Building Co.
, Ltd.
took a fancy to the technology of Japan's Tengcang Cable Company and decided to import this batch of 10 kV hoisting cables
from Japan.

Overcome difficulties and break through technological monopoly with innovation

So how did Far East Cable break through this technical bottleneck and break the technological monopoly of Japanese enterprises? It relies on innovation and the spirit of
never admitting defeat.
Jiang Xipei, founder, chairman of the board and secretary of the party committee of Far East Holding Group, once vowed: Landmark buildings standing on Chinese land must use our Chinese cables
.
It is under the guidance of this belief that the Far East Cable technical team broke through the traditional lifting force method according to the power supply design requirements, and successfully developed the hanging cable and spreader for super high-rise buildings by reducing the weight of the cable body and improving the bending performance, and finally won the recognition
of the investors and builders of Shanghai World Financial Center 。 Among them, the longest cable is 708 meters long, weighs 14 tons, and has a lifting height of 131 to more than 400 meters, which is installed in the underground horizontal section, vertical section and high-rise horizontal section, which is the first time in the domestic super high-rise building hanging and dressing facilities at that time
.

Compared with the traditional steel wire armored cable, the ampacity of the hanging laying cable for super high-rise buildings developed by Far East Cable is increased by about 10-30%, the weight of the cable is reduced by 20-30%, and the whole cable has no intermediate joint, which greatly enhances conductivity and safety; In addition, the cable hanging section adopts a self-bearing unit, embedded in the vertical section of the cable 3 wire ropes, and equipped with a lifting disc, the wire rope and three cable cores are twisted, in the process of hoisting and long-term energized operation, the wire rope and the lifting disc are stressed, no matter how long and heavy, can support its own weight, which effectively guarantees the safety of
the building power supply system.

When laying and installing, the cable is hung in the shaft without a bridge, and the special spreader is installed and laid, which has a compact structure, small space occupation, and safe and reliable
bearing.
It not only effectively solves the construction and installation problems, but also saves installation costs and improves the overall economic benefits
.
At the same time, the cable also adopts environmentally friendly design, which has excellent halogen-free, flame retardant, fire resistance, low smoke production, low heat release and other characteristics, realizing green building safety, environmental protection, intelligent and economical power
supply and distribution.

Improve specifications and fill gaps in standards

Innovation knows no bounds
.
Through continuous exploration and research and development, Far East Cable has gradually formed a complete set of installation and laying specifications, and edited the group standard of the Architectural Society of China "Hanging Cables and Spreader for Super High-rise Buildings", which fills the standard gap in the industry and field, and has important guiding significance for the future construction and development of super high-rise buildings, and also "escorts" the safe operation of many super high-rise buildings, such as China Zun
.

In view of the special situation of continuously and safely arranging twelve cables in a strong electric well with a width of only 450mm, Far East Cable has created a number of "world firsts" such as 820 meters of special 10kV high-voltage hanging cable laying and a plate double hanging spreader, laying a total of 24 hanging cables, with a total length of 15,132 meters and a total weight of 136.
38 tons, ensuring the safe operation
of China Zun.

Over the years, Far East Cable has always adhered to the design, research and development, production and sales of intelligent cable products in the field of construction, actively served the intelligent development of super high-rise buildings, led the major changes in the power supply mode of super high-rise buildings, and contributed Far East technology and Far East solutions
to the development of super high-rise buildings.
