China is a country lacking in copper resources. With copper heavily relying on imports, people in China have long been looking forward to having a new type of conductor material to replace the scarce copper conductor material. It can be said that the idea of "popularizing aluminum alloy cables with aluminum" has long been expected by the Chinese people for years. As the technology advances, it is possible to realize this. The advanced conductor aluminum alloy technology solves the...
For the wire and cable industry, the most obvious material alternative is to use aluminum conductors instead of copper conductors. In the copper, aluminum cable relative cost, you need to consider the price, weight and conductivity and other factors, in order to draw the aluminum conductor is the real cost-saving answer. Copper is heavier than aluminum. The specific gravity of copper is 8.9g.cm3, the specific gravity of aluminum is 2.7g / cm3, that is to say, the weight of copper conductor is...

The 10 meter frequency band is the highest frequency band in the HF band. This band has many magical characteristics. Because the attenuation of the ionosphere is very small when it is open, even with small transmission power, unexpected long-distance communication can be performed. Due to the high frequency of the 10 meter frequency band, the small size of the antenna, it is easy to make and set up, and the cost of the materials used for manufacturing is low. As long as it is made, set up and...

Because the hull is affected by ocean waves, random sway (rolling, pitching, yaw) will cause the antenna's boresight to sway, which can easily cause the tracking performance of the narrow-beam antenna to deteriorate and even cause the target to be lost. In order to accurately track the target and reduce the disturbance caused by the movement of the carrier to the antenna tracking, it is necessary to establish an anti-disturbance stabilization system to make the antenna output visual axis...
In order to complete the ocean-going space measurement and control and communication business, large precision tracking antennas should be installed on the measurement and control and communication measurement ship. Because the hull is affected by ocean waves, random sway (rolling, pitching, yaw) will cause the antenna's boresight to sway, which can easily cause the tracking performance of the narrow-beam antenna to deteriorate and even cause the target to be lost. In order to accurately...
At the end of 2010, the total number of mobile phone users in China was 859 million, and the total number of 3G users was 47.1 million; in July 2011, the total number of mobile phone users in China rose to 930 million, of which the total number of 3G users reached 87.2 million. The large-scale growth of mobile users and communication data traffic has prompted telecom operators to continuously optimize and expand their networks. Shuiqing Muhua Research Center pointed out that in 2011 China's...
