On the highway, the barbed wire protective net is generally used to prevent people and animals from crossing the highway at will, so as not to interfere with driving and reduce accidents, as well as effectively prevent illegal occupation of highway land and other issues of traffic safety facilities. There are many forms of barbed wire protective nets, commonly used are metal, woven nets, barbed wire and evergreen green gracilaria. In the densely populated areas set up metal woven net, people and animals are less sparse areas of the form of barbed wire, in the toll station, service area and other sections of the structure of hedge and barbed wire. In the past two years, considering the aesthetic problem, some highways in the Pearl River Delta region adopted the fruit plastic spot welding mesh (usually said guardrail mesh), the barbed wire protective mesh is more beautiful, but also durable, the overall effect is good, but the construction requirements are higher, more expensive. General sections should not be used, in the city center, scenic spots or strong requirements for beauty of the section available.

4, the material requirements of silk: wire drawing weaving, electric galvanized wire weaving, hot galvanized wire weaving, first woven after hot plating.

Large roll galvanized wire is like the literal meaning, is wrapped in a layer of zinc on the surface of low carbon steel wire material, beautify the appearance at the same time, but also improve the corrosion resistance of galvanized wire. Zinc dissolves easily in acids and alkalis, so it is called a dissoluble metal. Zinc changes little in dry air. In moist air, a dense basic zinc carbonate film forms on the surface of zinc.

According to the habit often according to the basic galvanized hardware before plating treatment method, as long as it does not contact with water can keep 5~7 years or so without rust, of course, if it is a salt water test, it will not be over 4 hours. Hot dip zinc is to use zinc tin solution to cover the hardware, and the rust prevention time is about five times that of traditional galvanizing. The general outdoor construction is to use hot dip zinc, and the salt water test can do about 36 hours.

Insulating Motor Connections For Reliability

Insulating tape, also known as electrical tape, is a commonly used tool for insulating and protecting electrical wires and cables. It is typically made of PVC material and has a pressure-sensitive adhesive on one side that allows it to adhere to various surfaces.

You can, but it’s not the best idea.

(3) Even if it is wound around sharp complex shapes, it is still well sealed, waterproof, uniform and smooth, and can still maintain high insulation performance in high humidity environment;

According to Steve Anderson, a National Joint Apprenticeship and Training Committee (NJATC) director, the NJATC believes strongly in the importance of splice and termination taping skills for electricians and linemen. “Taping is the first thing covered in our cable splice training course, and we spend a lot of time in this area,” Anderson says.
