| 注：1.阻燃型本安用控制电缆型号只需在表中型号前加ZR, 如ZR-IA-DJYPV 2.低烟无卤胡天的本安用控制电缆型号只需在表中型号前加WDZ, 如WDZ-IA-DJYPV 3.因低烟无卤和低烟无卤料均为阻燃料，故型号中ZR可省去。 4.耐性105℃型本安用控制电缆型号只需在表中型号后加-105，如IA-DJYPV-105;ZR-IA-DJYPV-105 Note：1.Flame-retardant type control cable for intrinsically safety circuit only need add“ZR”before type Of the table such as ZR-IA-DJYPV 2. For low-smoke,free-halogen sheath control cable for intrinsically safety circuit only need add“WDZ”before type Of the table such as WDZ-IA-DJYPV 3. Because low-smoke,low-halogen and low-smoke free-halogen compound are flame-retardant compound，“ZR”may be omitted 4.
