我是搞电缆的,虽然有个别地方可能还不是吃得很准,但我想我已把原文的信息都反映出来了.
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料
VW-1 = Vertical Flame test (formerly FR-1)
VW－1＝垂直燃烧试验（原先是FR－1试验）
60°C = Standard temperature rating (except HPN - 90°C
60℃＝标准温度额定（除了HPN为90℃以外）
105°C = Electri-Cord's alternate rating (we normally don't stock 75°,90°C)
105 ℃＝软电线的交流额定（我们通常不库存75℃、90℃的产品）
IEC,ICC = International Color Code on the inner conductors (Blue,Brown,Green w/Yellow Stripe)
IEC,ICC＝内导体上的国际色码（蓝、橙、绿、w/黄色条纹）
N.A.= North American Color Code on the inner conductors (Black,White,Green)
N.A.＝内导体上的北美色码（黑、白、绿）
41/34 = Stranding - 41 strands of 34 AWG wire for each inner conductor
41/34＝绞合－用于内导体的34号美国线规金属线的41股绞线
T.C.= Tinned Copper inner conductors
T.C.＝镀锡铜内导体
RIBBED = Outer jacket is striated with ribs
RIBBED＝外护套带有脊型的条纹
R/S or W/S = Red or White Stripe for visual polarity inspection on Flat wire
R/S或W/S用于扁平导线目测极性检验的红条纹或白条纹
问题补充：UL线规代号和含义
UL没有线规,它是个认证机构,有一系列适用不同类型、规格电线的试验标准.AWG美国线规才表示金属线的规格,很容易查到.
