Comments: The impact of the property "purchase restriction" on the wire and cable industry

Wire and cable is an indispensable building materials in the real estate industry, with the implementation of the property "purchase restriction", also affected to a certain extent, but with China's investment in the power grid and the construction of light rail will bring greater opportunities for the development of wire and cable, especially the average annual growth of power conductors and cables up to 15%.

Cables can be divided into electromagnetic wires and general-purpose insulated wires according to their main applications

The difference between wire and cable depends on the size of the wire is generally small, the electrical conductor cross-section is very large (more than 6 square millimeters) called large wire and cable, smaller (less than or equal to 6 square millimeters) called small wire, insulated wire is also called cloth wire. But sometimes the cable is also classified as theoretical wire.

AWG calculation method

AWG is another way of making into DWDM. A grating formed by a set of optical waveguides arranged in a specific length is used to have the ability to split waves. It is mainly used in the production of high-density wavelength multi-T./demultiplexer (DWDM). Its principle is: first the light source to start using (including a variety of wavelengths of light modulation signal) through the splitting element into several to dozens of roughly equal amplitude sub-sources, and then these sub-sources into the pre-designed length of the array waveguide......
