请问电源线SPT/SJT/SVT规格是代表什么意思？

(1).美规电线(flexible cord)参考的标准为UL62、UL1581.
SPT、SJT、SVT
SPT-1:(Service Parallel Thermoplastic)热塑型平行线.最大可生产到20~18AWG(2芯或3芯)
SPT-2:最大生产到18~16AWG(2芯或3芯)
SPT-3:最大生产到18~10AWG(2芯或3芯)
SVT(Service Vacuum thermoplastic):18~16AWG(2芯或3芯)
SJT(Service Junior thermoplastic):18~10AWG(2芯~5芯)
ST:18-2AWG(2芯或多芯)
l 印刷要求:UL规定电线上必须印UL、CSA logo,最低60℃可印也可不印,印字之间距不 可超过610mm.
l UL E135710<档案>

SPT-1 SPT-2 SPT-1W SPT-2W SPT-3 NISPT-1 NISPT-2 SVT SJT SJTW ST STW l CSA LL95937<档案>
SPT-1 SPT-2 SPT-3 SVT SJT
l UL与CSA对电线的温度对照
