Requirements for environmental conditions of explosion-proof motors and description of special environmental code

For motors used under special environmental conditions, the special environmental code should be added after the motor model when ordering.
Climate-protected places: indoors or places with better shelter (the building structure can prevent or reduce the impact of daily changes in outdoor climate, including the conditions under the shed).
Non-climate-protected places: places in the open air or with only simple shelter (which can hardly prevent the influence of daily changes in the outdoor climate).
For the models used in special environments, there are certain special environment codes, and the special environment codes are represented by the following letters: "Gao" was originally code-named "G", "ship" (sea) was code-named "H", "Household" The code for "outside" is "W", the code for chemical anti-corrosion is "F", the code for "hot" belt is "T", the code for "humid heat" is "TH", and the code for "dry heat" is "TH". TA".
The special environment derivative series is essentially a structure derivative series. It makes some changes on the basis of the basic series structure design, so that the product has a certain special protection ability (such as explosion-proof, chemical anti-corrosion, outdoor and marine, etc.). Some structural components and protective measures of these series are different from the basic series. Environment derivatives are:
Humid heat type, code name for climate protection places is "TH"
Dry heat type, codenamed "TA" for climate-protected places
Tropical type, codenamed "T" for climate-protected places
Damp heat type, code name "THW" for places without climate protection
Dry heat type, code name "TAW" for places without climate protection
Tropical type, codenamed "TW" for places without climate protection
Indoor, light anti-corrosion type without code
Indoor, the medium anti-corrosion type code is "F1"
Indoor, the strong anti-corrosion type code is "F2"
Outdoor, light anti-corrosion type codenamed "W"
Outdoor, medium anti-corrosion type codenamed "WF1"
Outdoor, strong anti-corrosion type code-named "WF2"
