Ni veivosakitaki na ivakatagedegede ni itatarovi, na kena tubu na katakata ena kacabote-ivakadinadina moto sa yaco me veiganiti. Na ka dina, e rua na tikina bibi me na tarai kina na duavata:

Itatarovi ni Kalasi F:

Ena gauna oqo, sivia na 90% ni voltage cecere ka lailai na kacabote-ivakadinadina motors e Jaina o ira na kalasi F insulated. To extend the lifespan of explosion-proof motors, more than 90% of manufacturers indicate “Class F insulation, ivakarau ni katakata rise assessed by Class B limits” in their samples. Class B insulation allows a temperature of 130°C, while Class F permits up to 155°C. Considering an environmental temperature of 40°C, manufacturing process and material fluctuations of 5°C and 10°C, na volau ni nona temperature rise limit for Class B insulated explosion-proof motors is set to 80K, and for Class F, it is 90K (95K for underground explosion-proof motors).

Class H Insulation:

Class H insulation permits a temperature of 180°C. Ia, the design, buli iyaya, bearings, and lubricants for Class H explosion-proof motors are not yet widely applied in China. For manufacturers, producing Class H insulated windings is not difficult; the challenge lies in high-temperature bearings. O koya gona, unless necessary (such as in environments with temperatures of 60°C, or where motoka ni kacabote-ivakadinadina size is limited), the use of Class H insulated explosion-proof motors should be avoided.
