What is an industrial telephone?
The telephone has been more than 140 years since Bell invented it in 1876. Industrial telephone belongs to one of the special telephone categories under the category of fixed telephone in the telephone machine. Phone type is mostly wall hanging type.
Industrial telephone belongs toindustrial grade telephone products, compared with civil products, in the design concept, selected materials, built-in integrated circuit, protection test level, adapt to the environment of temperature and humidity have different levels of strengthening.
What are the categories ofindustrial waterproof anti-noise telephone?
According to the application scenario classification: pipe gallery optical fiber telephone, campus school family phone, tunnel industrial telephone, cold storage industrial telephone, highway industrial telephone, hydropower station industrial telephone, thermal power station industrial telephone, nuclear power plant industrial telephone, mining industrial telephone, chemical and petroleum industry telephone and other emergency special industrial telephone.
-------------------------
Classification according to the standard and transmission mode:
Analog telephone (telephone line transmission), IP (VOIP / SIP / WIFI) telephone (network cable / network transmission), optical fiber telephone (optical fiber transmission), etc.
-------------------------
Classification by fuselage material
Metal: aluminum alloy, cold-rolled iron, stainless steel
Non-metal: ABS high strength, SMC composite FRP, DMC composite FRP
-------------------------
By functional classification
Industrial waterproof telephone, industrial anti-noise and noise reduction telephone, industrial explosion-proof telephone, industrial anti-freezing telephone, industrial loudspeaker alarm telephone and other industrial protection telephone.
Protection grade (dust and waterproof grade) in industrial application, generally is: IP65, * * * is IP68. But the protection grade IP54 is low, IP is the marked letter, the number 5 is * * * marked number, 4 for the second mark number * * * marked number indicates contact protection and foreign protection grade, the second mark number is waterproof protection grade.
Related standard GB4208-2008 Shell Protection Grade
IP54, IP65, IP66, IP 66 are four common protection levels, among which IP68 grade is high
