The difference between the instrument cable and the low voltage power cable
Both use different. . fire bridge for 10KV following power cables, as well as control cables, lighting wiring and other indoor and outdoor overhead cable trench, tunnel laying. The fireproof bridge is mainly composed of glass fiber reinforced materials, inorganic binder composite fire board, and metal skeleton composite and other fireproof material composition, the outer layer plus fire retardant coating. Fire bridge after the fire will not burn, thus blocking the spread of fire. Fireproof bridge has a very good fire fire effect, but also has a fire, oil, corrosion resistance, non-toxic, non-polluting, the overall installation and so on. Fire retardant coating has a thin, high fire resistance, strong adhesion characteristics. . galvanized bridge, the main application in the wet, corrosive environment. According to the different production processes, divided into hot-dip galvanized and galvanized (ie, cold galvanized) two. Hot-dip galvanizing process: The process and method of forming zinc-iron alloy or zinc and zinc-iron alloy coatings on the surface of steel or castings immersed in molten zinc solution. Cold galvanized process: the surface of the steel chemical cleaning treatment into the plating solution, electroplating solution containing zinc oxide. DC a pole connected to the steel, a pole connected to the plating solution in the zinc plate. After the application of zinc to the molecular state of displacement to the steel surface. If the brightener passivation, then embodies the cloud-like bright coating. Application of galvanized steel in the general anti-rust effect is not very good, mainly galvanized capacity is not reached, and galvanized uneven, generally two or three years on the rust phenomenon, poor quality exposed to humid environment More than a few days on the rust. Hot galvanized coating thick, strong corrosion resistance. Cold galvanized galvanized layer is hot and bright, but thinner, corrosion resistance is weak.
If the words are used, the difference is not true if the front is the control cable, followed by the power cable
Two wire, to ensure that the surrounding quiet, with the ears to determine the clogging range, and then picked up the electric pick
