Zheng Cable manufactures copper-clad aluminum core power cables

Zhengzhou Cable (Group) Co., Ltd. has applied for a patent for a copper-clad aluminum conductor power cable and has already put this kind of power cable into production.

Copper clad aluminum core extruded insulation (PVC, XLPE) power cable is a new type of wire and cable. Copper clad aluminum is a new type of conductor material, which is copper and aluminum as the main material and produced through special processing technology. It makes full use of the respective characteristics of copper and aluminum and effectively compensates copper and aluminum conductors in wire and cable engineering. The disadvantages of the application, such as: high density of pure copper conductors, lack of domestic resources, high prices, and difficulty in laying, etc., aluminum conductors have low electrical conductivity, poor welding performance, easy oxidation of the surface, and large contact resistance. Copper-clad aluminum power cable has the characteristics of good electrical conductivity, easy welding, light weight, easy to lay and low cost, so it has been applied in the developed countries in Europe and America and has achieved good results.

The copper-clad aluminum core power cable developed by Zheng Cable uses heat-resistant PVC or heat-resistant XLPE as the insulating material. The long-term working temperature is as high as 105°C, and the transmission capacity is better than that of ordinary power cables. Other performance indicators conform to national or international standards.

Microscope Slides And Cover Slips

1. The glass slide is used to put the sample to be tested, and the cover glass is covered on the sample to be tested.
2. The glass slide is at the bottom, which is the carrier for the material you want to observe, that is, you want to put something on it.
3. The cover glass is smaller than the slide glass. The glass slide is mainly used to hold the observation objects. The cover glass is covered on the slide glass and used for fixing.
4. The glass slide is a thicker piece of glass in the transfer slide, which is used to carry the real object. The cover fragment is the small round or square thin one.
5. Mounting is a general term for a set of things, including slides, coverslips and loaded objects

6. The cover glass is square, the slide glass is rectangular, and the width is longer than the side of the cover glass.
