What is the difference between fully insulated copper tube bus and fully insulated aluminum tube bus?
Fully insulated copper tubular bus and Fully insulated aluminum tubular bus What's the difference? Tubular bus has never been a strange term in the power industry. With the great increase of power demand in modern society, the application of tubular bus in power transmission and distribution industry is deeply loved and recognized by the majority of owners. This technology, which was first introduced from Germany, has been improved and innovated in China, and has been developed to meet the requirements of domestic use, Among them, the most commonly used is fully insulated copper tube bus and fully insulated aluminum tube bus, so what is the difference between the two?
What is the difference between fully insulated copper tube bus and fully insulated aluminum tube bus? The fully insulated copper tube bus is used to shield the tubular bus. The conductive part of the insulated bus is made of high-purity electrolytic copper. The traditional main insulation material is polytetrafluoroethylene. The grading layer is composed of a semiconductor layer and a main insulation layer. The grounding shielding layer is woven copper mesh, and the outer insulation is polyolefin polymer insulation sheath. And the fully insulated aluminum tubular bus is The conductive part of tubular bus is made of aluminum alloy tube, and the insulation material, grading layer, shielding layer and outer insulation material are the same as that of fully insulated copper tube bus. However, our Guangdong High Power Technology Co., Ltd. has developed domestic innovative fully insulated copper (aluminum) tubular bus. The insulation layer is made of epoxy resin, and the outer layer is made of high anti-collision ability PVC pipe, which makes the performance and life of the product superior to the traditional tubular bus, is a popular tubular bus product in the market at present.
Fully insulated copper tube bus has good thermal conductivity and high low temperature strength. Because the copper tube is easy to process and connect, it can save material and total cost, has good stability and reliability, and has the nature of maintenance free.
The shape of copper is easy to change, because copper tube can bend and deform. It can often be made into elbows and joints, and smooth bending allows copper pipes to be bent at any angle. Aluminium Ductility Yes, but it's not as good as copper. Its specific strength is close to that of high alloy steel, and its specific stiffness is higher than that of steel. It has good casting performance, plastic processing performance, good electrical and thermal conductivity, good corrosion resistance and weldability. It can be used as structural materials, and is widely used in aerospace, aviation, transportation, construction, electromechanical, light chemical and daily necessities.
Fully insulated copper tube bus has good conductivity. For the same weight and length of copper aluminum tube bus, copper tube bus conductor performance is better, but the cost is relatively high, but the service life is longer.
Compared with fully insulated aluminum tube bus, fully insulated copper tube bus is more resistant to high temperature and can be used in a variety of environments without environmental impact. It is hard, not easy to corrode, and has high temperature resistance, high pressure resistance and strong applicability.
The linear expansion coefficient of copper tube is very small, which is 1 / 10 of that of plastic pipe. It will not cause stress fatigue fracture due to excessive thermal expansion and cold contraction.
