最新消息,最新標準UL2263-Standard for Electric Vehicle Cable(電動汽車線纜標準)于2022年05月09日發布第一版。電動汽車線纜原來被描述在UL62標準的4.8章節,現也全部被UL2263所取代,所在認證和測試時,切記一定要引用新的UL2263標準。

1、主要型號
UL2263 主要有6個型號,分別為 EVJ EV ; EVJE EVE ; EVJT EVT
第一組:熱固性材料絕緣型號:EVJ EV
Type EVJ — Rated 300 V, contains two to six 18-12 AWG thermoset-insulated circuit conductors, and may employ one or more insulated grounding conductors. The cable may contain hybrid data, signal, communications, and/or optical fiber cable in any AWG size.
型號EVJ 300V(供電線徑為:18-12 AWG) :使用的絕緣材料主要為熱固性材料(如EP, CR, CSM, CPE等)
Type EV — Rated 1000 V, contains two or more 18 AWG to 500 kcmil thermoset-insulated circuit conductors, and may employ one or more insulated grounding conductors. The cable may contain hybrid data, signal, communications, and/or optical fiber cable in any AWG size.
型號EV 1000V (供電線徑為:18-500 kcmil ) :使用的絕緣材料主要為熱固性材料(如EP, CR, CSM, CPE等)
備注:常用的熱固性材料有:
CR( polychloroprene,氯丁橡膠),CSM( chloro-sulphonyl-polyethylene,氯磺?;垡蚁?,
CPE( chlorinated polyethylene氯化聚乙烯) EP(ethylene propylene rubber,乙丙橡膠)
第二組:熱塑性彈性體絕緣型號: EVJE EVE
Type EVJE — Rated 300 V, same as Type EVJ except that the cable employs thermoplastic-elastomer-insulated conductors and jacket.
型號EVJE 300V(供電線徑為:18-12 AWG) :使用的絕緣材料主要為熱塑性彈性體材料(如TPE等)
Type EVE — Rated 1000 V, same as Type EV except that the cable employs thermoplastic-elastomer-insulated conductors.
型號EVE 1000V (供電線徑為:18-500 kcmil ) :使用的絕緣材料主要為熱塑性彈性體材料(如TPE等)
第三組:熱塑性絕緣型號: EVJT EVT
Type EVJT — Rated 300 V, same as Type EVJ except that the cable employs thermoplastic (PVC) insulated conductors.
型號EVJT 300V(供電線徑為:18-12 AWG) :使用的絕緣材料主要為熱熱塑性材料(如PVC等)
Type EVT — Rated 1000 V, same as Type EV except that the cable employs thermoplastic (PVC).
型號EVT 1000V (供電線徑為:18-500 kcmil ) :使用的絕緣材料主要為熱熱塑性材料(如PVC等)
2、電壓
This standard specifies the requirements for electric vehicle cables rated up to 1000VAC and DC.
UL2263電壓最高1000V AC 或DC ,主要300V, 600V ,1000V三個電壓等級。
3、溫度
It is rated 60 °C, 75 °C, 90 °C, or 105 °C
UL2263溫度等級為:60 °C,75 °C, 90 °C, 105 °C, 四個溫度等級。對比歐標EN50620和國標GBT33594的耐溫最高為90度,所以美國UL標準的溫度是要高出很多的。
60 to 105°C (140 to 221°F) dry:干燥環境(主要室內):60 to 105°C
60°C (140°F) wet: 潮濕環境:60°C
60°C (140°F) where exposed to oil: 耐油環境60°C
4、導體
Conductors shall be of annealed copper in compliance with ASTM B3 or NMX-J-036-ANCE, or annealed coated copper in compliance with ASTM B33 or NMX-J-008-ANCE.
導體主要為軟銅或電鍍軟銅, 合金銅和鋁合金這些金屬導體是不能選擇的。
5、線徑大小
Electric vehicle cable employs flexible stranded copper conductors in a size range of 18 AWG to 500 kcmil
主供電線的線徑:從18 AWG(0.824mm2 )到500 kcmil(253mm2),信號傳輸和控制線纜不受此約束。
6、絕緣材料和護套材料
The insulation and jacket are both thermoset on Types EVJ and EV, thermoplastic elastomer (TPE) on Types EVJE and EVE, and thermoplastic (PVC) on Types EVJT and EVT.
