Shielded cable and unshielded cable choice which is better?

The present application is the largest super five lines, in the material level is divided into the shielded cable (STP for each line has its own network, FTP shielding shielding layer of cable) and non shielded cable (UTP). Shielding cable relative to stronger anti-interference non shielded cable, and the transmission speed is slightly higher, but in the actual laying line both sides of the cable must be properly grounded can play a role, but also requires all related devices are shielded parts, including cables, socket,crystal head and distribution frame, building good ground contact.

Unshielded cabling casual is simple, and the manufacturing cost is lower than the shielding wire, suitable for home and office environment, if the use of line of environmental electromagnetic radiation is strong, for precision electronic equipment such as the environment, choose good shielding cable (STP).

The general Home Furnishing environment will choose electromagnetic radiation from smaller places, so the use of non shielded cable is enough for the daily life of the family, office wiring also belongs to the electromagnetic interference small area, also can use unshielded cables.

For some high (substation, electromagnetic radiation research room) environment must use shielded cable, attention must be paid to the shielded cable must be connected to ground, and the whole transmission components with shielding material and are connected to ground, or the signal is susceptible to interference.

Non shielded cable is applicable to most of the living environment, and the price is cheap, simple laying; shielding cable strong anti-interference ability, high transmission speed, but the price is high, the laying of the more difficult. Therefore, should be based on the line to select the corresponding environmental type cable.
