Q:What is the antenna cable

Divided into four layers, the innermost layer is the inner conductor layer, generally single or multi-strand copper for the best; then the insulation, with plastic, etc .; then the outer conductor layer, usually copper or copper

Q:Shielded twisted pair how to play a shielding effect?

Therefore, the entire system is required to shield the device, including cables, sockets, water [1] crystal head and patch panels, etc., while the building needs a good ground system.

Q:What kind of copper net radiation (shielding) the best effect?

The larger the mesh, the smaller the mesh. Specifically how to use to see what shield, the wavelength is how much, and then choose the copper mesh material, specifications, mesh and so on.

Q:Can copper wire prevent radiation?

One is the coating of pregnant women's radiation clothing. The shortcomings of this radiation suit is hard, breathable, can not be washed, and plated metal easily fall off into powder, such as pregnant women inhalation, will affect the healthy growth of the fetus.

Q:Barbed wire and copper mesh which shield effect is good

For the signal shielding, copper wire shielding effect is good.

Q:What is the material of the clamp material

(Such as marble slabs, granite slabs, cast slabs, etc.) to ensure the close combination of the inserts and the walls and the ease of construction. The tiles themselves are light and thin, and when they are attached, the hanging net is tantamount to superfluous.

Q:PE copper mesh skeleton plastic composite pipe connection in several ways?

The two kinds of melt are melted together, and after the cooling molding, the pipe is tightly connected with the pipe

Q:Is the cable wrapped in the electrical insulation layer and the insulation layer is not the same layer?

Filter to copper mesh as a filter material, in the surrounding open a lot of holes in the plastic or metal cylindrical skeleton, wrapped in a layer or two layers of copper mesh, the filter accuracy depends on the copper layer and the network of large school

Q:How to prevent the frequency of magnetic field? What material can protect 110KV high voltage electromagnetic radiation? Barbed wire or copper mesh is anti-high frequency or anti-low frequency?

Steel mesh as far as possible in the side of the wire but to maintain a sufficient safe distance with the wire. But remember. Steel wire mesh must be reliable ground to be effective.

Q:What is the mesh filter for the dry filter?

If the refrigerator system configuration is very good, the resulting impurities are few, will not cause ice blocking and other issues, the life of the dryer in 7-10 years.
