Climbing the peaks of the plateau, Sansi LED lights up Yunnan Tianlu
Yunnan is an important gateway for China's “One Belt, One Road†strategic planning. Rational use of superior geographical conditions, Yunnan is actively building a three-dimensional high-speed traffic skeleton network inside and outside. Among them, only in 2015-2016, Shanghai Sansi has built a number of Yunnan high-speed LED lighting and LED display projects such as Longjiang Bridge, Mazhao Expressway, Shanghe Expressway, Xiaomo Expressway and Longrui Expressway, with an amount of nearly 100 million yuan. Bright Yunnan high-speed skeleton network.
Yunnan Tianlu, comparable to the road
Yunnan is a plateau mountainous area with steep terrain, steep terrain and complex structure, which makes the construction of high-speed lighting facilities complicated and difficult to construct. In addition, the altitude difference in Yunnan is large, and extreme weather such as extreme heat, extreme cold, dense fog, snow, freezing rain, and ice icing often occur. High-speed lighting fixtures and display products are subject to harsh weather tests.
Faced with the severe environmental factors in Yunnan, there are bound to be strict quality requirements for LED lighting and LED display products used on expressways. The Yunnan High-speed Administration is cautious about the choice of high-speed LED application products. After many comparisons, Shanghai Sansi has won many high-speed LED lighting and LED display projects in Yunnan with its stable and reliable performance and excellent quality.
Asia's first bridge that shocked the world
The Yunnan Longjiang Bridge, which was built by Shanghai Sansi, is a miracle on the Hengduan Mountains in the Himalayas. The bridge is built in the high-intensity strong earthquake mountain area. The volcanic landforms are mostly along the way, the mountains are high and the valley is deep, and the geology is extremely complicated. The bridge is a twin-span single-span steel box girder suspension bridge with a total length of more than 2,470 meters. It is the largest steel box girder suspension bridge in Asia.
Sansi provides a full line of lighting equipment for the Longjiang Bridge. Sansi LED street light adopts simple and elegant arc shape design. The core lamp bead adopts standard module with unique lens design. The outer casing is made of high quality aluminum die-casting, with high protection level and stable and reliable operation. Against the backdrop of Sansi LED streetlights, overlooking the bridge, it is like two giant dragons flying in the clouds and clouds, flying over the cliffs and swaying through the misty clouds.
The Longjiang Bridge is an important section of the Yunnan Baoteng Expressway. It connects Tengchong, the most beautiful town in western Yunnan, and is one of the high-speed skeletons in Yunnan. In order to improve the backbone road network structure of Yunnan Highway, only in 2015-2016, Sansi will build a number of high-speed LED lighting and LED display projects to light up the Yunnan high-speed skeleton network.

The Mazhao Expressway, built by Sansi, is the most complex and climatically high-speed geological condition in Yunnan. It is also the first green and low-carbon highway in Yunnan and the first in the country. The Shanghe Expressway is an important channel connecting the north and south of Dali Prefecture in Yunnan. The expressway is the main thoroughfare connecting central and southwestern China and leading to South Asia and Southeast Asian countries. It is a typical demonstration project by the Ministry of Communications. Longrui Expressway is one of the “four exits†international channels that Yunnan has promoted.
Sansi provides tens of thousands of LED tunnel lights and gantry-type information boards, F-type information boards, full-color displays, mobile information boards, and variable information boards in the cave for high-speed LED applications. Technological innovation technology. Among them, the ceramic modular LED tunnel light is an important achievement of the "863" project. It has the patented technology of "reflective LED lighting" and ceramic heat sink and honeycomb convection heat dissipation technology. The light is uniform and soft, the heat dissipation efficiency is high, and the service life is significantly prolonged. . In addition, the Sansi LED application products are perfectly adapted to the intricate application environment of the plateau with excellent protection technology and excellent use effect.
The rugged terrain of Yunnan has created a beautiful landscape, which has also made it difficult to get on the road. Since the opening of the five-foot road in Qin, people have been paving the road for more than two thousand years, and finally formed a traffic skeleton network that is smooth and convenient today. Among the many traffic skeleton networks, Shanghai Sansi LED application products are lighting Yunnan Tianlu with excellent and reliable quality.
Rectifier bridge is to seal the rectifier tube in a shell. Points full bridge and half bridge. The full bridge connects the four diodes of the connected bridge rectifier circuit together. The half bridge is half of four diode bridge rectifiers, and two half bridges can be used to form a bridge rectifier circuit. One half bridge can also be used to form a full-wave rectifier circuit with a center-tapped transformer. Select a rectifier bridge to consider. Rectifier circuit and operating voltage.
