美规线规的代号及含义
**** Hidden Message ***** 学习美规线规的代号及含义 Flat Wire:扁平导线
SPT: Stranded, Parallel, Thermoplastic
SPT:绞合的、平行的、热塑性塑料的
This is always followed by a -1, -2 or -3, signifying insulation thickness for different applications.
这后面总是跟着-1,-2,或-3,以象征不同应用中的绝缘厚度。
HPN: Heater, Parallel, Neoprene
Required for heater-type application, such as irons, toasters, etc.
HPN:加热器,平行的,氯丁橡胶
要求用于加热器类型的应用场合,比如电烙铁、烘烤机(吐司炉)等
NOTE: We can run some 20 AWG, but mostly we run 18, 16 and 14 AWG, 2 or 3 conductors. P is always Parallel Wire (Flat).
注意:我们可以经营一些20号美国线规的规格产品,但大多数经营18、16和14号美国线规,2芯或3芯的产品。P总是指平行导线(扁平导线)
Jacketed Wire:
护套线
S = Stranded (or Service Wire)
S=绞合的(或入户线、引入线)
说明:service wire在电缆中有时是业务线,如通信电缆中传业务电能或信号的线。
J = Junior Service (300 Volt).
J=初级服务(300伏)
If no “J“ is in the wire type, then it is a hard service (600 Volt).
如果在电线型号中没有J,那么该电线是重负荷工作状态(600伏)
T = Thermoplastic.
T=热塑性塑料的
If no “T“ is in the wire type, then it has a rubber jacket.
如果电线型号中没有T,那么电线采用橡皮护套
O = Oil-Resistant Compound
O=耐油电缆料
W = Weather-Resistant Compound
W=耐候电缆料
V = Vacuum - as in vacuum cleaner.
V=真空-如在真空吸尘器中
This is a small O.D. jacketed wire, very flexible and initially used for vacuum cleaners but now used on many different types of products. Available only in 18
AWG.
这是一种小外径的护套线,非常柔软,最初用于真空吸尘器,但现在用于很多不同类型的产品中。只有18号美国线规的产品。
Examples:
举例说明:
SV = Stranded Vacuum Rubber Jacketed (NO “T“)
SV=绞合的真空橡皮护套(没有T)
SJT = Stranded Junior Thermoplastic
SJT=绞合的初级服务热塑性塑料(护套)
SJTOW = Stranded Junior Thermoplastic,
Oil and Weather resistant for UL and CSA.
SJTOW= 绞合的初级服务热塑性塑料(护套)耐油、耐候,符合UL和CSA认证
说明:UL美国保险商实验室,CSA加拿大标准化协会
Miscellaneous requirements:
各项要求:
S.P. = Surface Printed
S.P.=表面印字的
N.M. = Non-Migratory compound to prevent the wire color from bleeding under unusual circumstances.
N.M.=防止电线颜色在非通常情况下渗色的非迁移性电缆 谢谢咯,哈哈 很好的學習了 受益多多,谢谢! 学习了,谢谢!
