“This year, domestic aluminum alloy cable is very hot, but it should be noted that the advantage of copper in high conductivity and high reliability is very obvious, which makes the speculation of aluminum alloy wire and cable impractical.†On November 21 The Asian Copper Week held by the Asian Copper Association met with the media. Zhou Sheng, president of the Association of China and South East Asia, answered the media's question on aluminum substitute copper. It is reported that in 2012, the total output value of China's wire and cable industry has reached a record 1.2 trillion yuan, ranking first in the world. With the huge industrial output value spawned, there has been a growing demand for “copper-based copper†in recent years because, from a cost perspective, the price of aluminum alloy cables is about 40% lower than that of pure copper cables, and copper cables are Cases of price theft were repeatedly reported in newspapers. However, in spite of this, Zhou Sheng still believes that in view of China's increasing emphasis on the safety, reliability and environmental protection of wire and cable, the future use of copper in wire and cable will have a brighter future. "It should be pointed out that the performance of copper on the cable connection is very safe and reliable, and this point, aluminum alloy cable is difficult to compare with it." Zhou Sheng frankly. It is understood that copper core cable connection performance is more stable, and will not cause accidents due to oxidative corrosion; aluminum core cable has the potential risk of heat due to oxidation caused by contact resistance, and thus cause accidents, so the safety is relatively lacking . In addition, Zhou Sheng also said that the current level of electrical installation in China is still at a relatively low level. According to research conducted by the National Fire Protection Association, fire caused by the failure of electrical lines accounts for two-thirds of the total electrical fire. In this case, the installation of the line and the selection of the line are all the more important in China. "Even if the installation specification, personnel technology, etc. are not in place, the possibility of problems with the copper cable line is very small, but if it is replaced with aluminum alloy, it will not be." In terms of safety, copper cables are difficult to compare with aluminum alloy cables. In addition, from an environmental point of view, Zhou Sheng believes that copper cables are also irreplaceable. “From the point of view of sustainable development, aluminum alloys are difficult to recycle, and even if they are recycled, they can only return to the form of alloys, but copper can be recycled 100%, of which the copper wire is one of the main forms of recycling. From an environmental point of view, the use of copper wire will continue." President of International Copper Association John? Hollander supplemented this issue by saying that “the problem China currently faces is the restriction of resources. If purely from the perspective of front-end cost, aluminum alloy is indeed cheaper than copper, but if it is from the perspective of recovery rate, the regeneration of copper Sex advantage is incomparable."

Wedge prism has
plane inclined surfaces. It deflects light toward its thicker portion.
It can be used individually to deflect a beam to a special angle. Two
wedge prisms work together can assembly an anamorphic prism to correct
the elliptical shape of laser beam. The wedge prism is ideal for laser
beam steering applications.We can make deviation angle from 1deg to 10deg. Other angle can
be realized upon request.Custom optical wedges and
thin wedge prisms used in variety of applications. Flat optical wedged
windows with a wedge angle are typically used in laser applications for
beam steering and beam displacement or for preventing stay-back
reflections,but can also be used in virtually any type of optical
component to change the direction of light.
