After four years of scientific research, Anhui Xinyi Cable Company has successfully developed the “aluminum alloy cable†and cracked the technical problem of “aluminum substitutes for copper†in cable conductors that have not been broken through for years. An expert review organized by the Science and Technology Development Promotion Center of the Ministry of Housing and Urban-Rural Development believes that the comprehensive performance of this technology has reached the international advanced level and has great value for promotion and application.
According to reports, unlike the traditional copper core cable, this kind of aluminum alloy cable adopts high elongation aluminum alloy material. Through the addition of iron and other materials in pure aluminum, and through the press-stranding process and special annealing, the alloy aluminum The gap in the "squeeze" clean and reduce the cross-sectional area, so that the cable has a good flexibility. This aluminum alloy cable is also superior to the copper core cable in terms of safety performance. When the surface is in contact with air, a thin and strong oxide layer can be formed to withstand various corrosion. Even when overloaded or overheated for a long time, the stability of the connection can be guaranteed. To achieve the same electrical performance, the direct procurement cost of aluminum alloy cable is 40% lower than that of copper cable, and the general construction and installation cost can save more than 20%.
Globe Valves and angle valves are designed for throttling or regulating flow in commercial and industrial applications. Bronze, cast iron, or cast ductile iron materials. Threaded, flanged, or solder end connections.
Angle valves for use in commercial and industrial applications. Typical services include hot and cold water, HVAC, steam, compressed air, gas and other general utility services.
Vacuum angle valve is used for turn on or shut off the airflow in the vacuum pipeline, the applicable media is air and non-corrosive gases.
It has two structures, one is angle type and another is a 3-way type within an ISO-KF or ISO-F various flange end pre-pump port.
a) Small diameter (≤DN50) valve body are precision investment casting.
b) Large diameter (> DN50) valve body are molding shaped seamless steel or steel plate.
c) Bellows sealed structure can withstand 150ºCtemperature, metal sealed structure can withstand 450ºCtemperature.
d) Can install on any position to control the airflow in the vacuum pipeline, as an on-off valve purpose
