Inona nytelefaona indostrialy? School / pipe gallery waterproof and anti-noise special telephone classification, emergency explosion-proof / mining with this safety type telephone manufacturers

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

Contact protection and foreign protection class (number 1)

Waterproof protection grade (number 2)


Scope of protection



Scope of protection



Tsy misy fiarovana



Tsy misy fiarovana



Protect against a 50mm diameter and a larger solid foreign body

Detector, with a sphere diameter of 50mm, should not be fully entered


Water drop protection

A vertical water drop should not cause damage


Protection against 12.5mm diameter and larger solid exotics

Detector, with a sphere diameter of 12.5mm, should not be fully entered


Protective water droplets when the cabinet is tilted by 15 degrees

When the cabinet is tilted to either side by 15 degrees, the vertical water drop should not cause damage


Protect against a 2.5mm diameter and a larger solid foreign body

Detector, with a sphere diameter of 2.5mm, should not be fully entered


Protect the splash of water

Water splashed from both sides of the vertical line at a 60-degree angle should not cause damage


Protect against a 1.0mm diameter and a larger solid foreign body

Detector, with a sphere diameter of 1.0mm, should not be fully entered


Protective spray

Water spray directed at the cabinet from each direction shall not cause damage


Protect the dust

It is impossible to completely prevent dust entry, but the amount of dust entering will not cause harm to the equipment


Protective shooting water

Water injection directed at the cabinet from each direction shall not cause damage


Dust closed

Dust should not be entered in the cabinet at a low pressure of 20 millibar


Protect against strong water

The strong water directed at the cabinet from each direction should not cause damage

Note: The diameter of the detector shall not pass through the hole of the cabinet


Protection for short-term immersion

When the cabinet is temporarily immersed in water under standard pressure, there should be no water immersion that can cause damage


Protection for long-term immersion

It can be immersed in water under specific conditions, and there should be no water immersion that can cause damage
