Theoretically speaking, the shielding network cable business outsourcing has metal material shielding layer, its anti-interference ability should be stronger. However, the shielding of network cables requires that all system software must choose shielded components, and the fireproof cloth also stipulates that the building has excellent grounding protection, otherwise it is very likely to make the shielding layer of network cables into interference signals. Therefore, if the non-unique must and standard has, the Internet wiring selection of non-shielded network cable.Flame retardant fabric
Fire cloth is not what we often say can not fire cloth, it has a unique solution, can block the spread of fire, in a certain time to fully automatic extinguishing. Therefore, the flame retardant grade of textile is generally determined by the ignition speed of textile. In other words, the flame-retardant carded fabric touches the flame for a certain period of time in the required manner, and then the flame is removed to determine the re-flame and flame ignition time of the fabric, as well as the level of damage to the fabric. The less the flame ignition time, the less the non-flame ignition time, Flame retardant fabric the lower the damage level, the higher the flame retardant grade of textiles; This, in turn, indicates that the textile has a poor flame retardant rating.
At present, twisted pair cables can be divided into unshielded twisted pair (UTP=UNSHILDEDTWISTEDPAIR) and fireproof cloth shielded twisted pair (STP=SHIELDEDTWISTEDPAIR). What do you mean, block it out? A simple understanding is to wrap aluminum around the outside of the 4 pairs of network cables, similar to the layer of aluminum and platinum outside the satellite signal line. The purpose of shielding: shielding the system software is to better ensure the transmission characteristics of the system software in the natural environment with interference signals. The anti-interference ability here should contain 2 levels, that is, the ability to resist external interference signals and the ability of the system software to work outward radiation source interference signals.Flame retardant fabric
Fire safety data signal cable: generally flame retardant/fire retardant blue and red twisted-pair soft cable (red positive and blue negative), smoke detector, temperature detector manual alarm button data signal control module and other connected to the data signal cable. For example, water flow indicator, wet alarm valve, smoke exhaust fire valve, quick exhaust valve and other control modules are connected to the data signal line and the alarm equipment according to the data signal. Switching power cable: Generally flame retardant/fireproof black and red twisted pair soft wire or flame retardant BV hard wire (red positive and black negative). The module must be connected with both the data signal cable and the switching power cable.
