As the chief architect of China Construction International Design Consultancy Co., Ltd., “Water Cube†is undoubtedly the most beautiful work worthy of showing off in Zheng Fang’s design career. In more than four years of design and construction, this world's most advanced polyhedral space steel frame structure technology, the world's largest, most complex structure, the most comprehensive membrane structure installation engineering and the most advanced environmental protection and energy saving technology is equal to The Olympic venues, the design team composed by Zheng Fang and colleagues experienced an insurmountable and difficult breakthrough, and finally turned the design concept of “water house full of bubbles†into the “water cubeâ€.
At the festive moment of the completion of the "Water Cube" today, Zheng Fang walked into the evening newspaper dialogue room and revealed to the readers of the evening newspaper the secrets of this crystal-clear "water house" that was unknown.
Evening News: Why is the final scale of the “Water Cube†smaller than it was originally designed?
Zheng Fang: At the time of design, the size of the original "Water Cube" was 194 meters long and 35 meters high. Later, considering the factors of saving construction cost, controlling the scale of the building and reducing internal energy consumption, the designers The plan was reduced, and the length and width of the Water Cube was finally determined to be 177 meters, while the height was reduced to 31 meters.
Evening News: The appearance of the “Water Cube†looks like some transparent soap bubbles stacked together. What kind of new material is used?
Zheng Fang: More than 3,000 irregular bubbles that make up the "Water Cube" skin are air pillows made of a new environmentally friendly energy-saving material, tetrafluoroethylene film (ETFE). The air pillows composed of these two inner and outer films are not the size. First, the shape is different, the largest is about 9 square meters, and the smallest is less than 1 square meter.
Thirty years ago, ETFE film was first put into use as an aviation material, and was later adopted as a building material by the Allianz Arena in Munich and the Garden of Eden in the UK. Although its thickness is only 0.2 mm, the ETFE film has good ductility and pressure resistance. The 1 meter long film can be stretched to 3.5 meters long and has a melting point of 275 degrees Celsius. Therefore, it is called "plastic king".
The “Water Cube†uses a total of 110,000 square meters of ETFE film, which is the largest ETFE film building in the world. At present, a factory has been set up in Shunyi. The cost of the domestic ETFE film is not as expensive as people think, probably just like the glass curtain wall.

Consumer Electronic Cable Assembly
Consumer electronic Cable Assembly: The product is mainly used in the signal, power, power transmission machine control inside the home appliance.
Common consumer electronic cable assemblies include air conditioner power wiring harnesses, water dispenser wiring harnesses, computer internal power cords, coffee machines, egg beaters and other signal lines, TV wiring harnesses and other product wiring harnesses that we can call white goods. The wiring harness is the main body of the circuit network. There is no home appliance circuit without a home Wire Harness . At present, whether it is a high-end luxury home appliance or an economical ordinary home wire harness, the braided form is basically the same, which is composed of wires, connectors and wrapping tapes. Home appliance wires, also known as low-voltage wires, are different from ordinary household wires. Ordinary household wires are copper single-core wires with a certain hardness. The consumer electronic wire harnesses are all copper multi-core soft wires, some soft wires are as thin as a few hairs or even dozens of soft copper wires are wrapped in a plastic insulating tube (polyvinyl chloride), which is soft and not easy to break. Common specifications of wires in consumer electronics harnesses include wires with a nominal cross-sectional area of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0, etc. square millimeters, each of which has an allowable load current value for use in different power electrical equipment. Different gauge wires.
The consumer electronics connection cable harness industry has had a profound impact on people's lives, cutting into all aspects of life from market conditions, industry services, service conditions, and market scale. Therefore, Kable-X has made an in-depth understanding of the consumer electronics industry to provide customers with better wiring harness.
In addition to Instrumentation Cable Assembly, we also have Vehicle cable assembly and Industrial Cable Assembly.
