因为会涉及到一些电气的专有名词,所以那些翻译软件基本翻译不大对头,
Presently,all the emerging designs have one thing in common — the use of composite material technology.
Aluminum conductor carbon fiber reinforced (ACFR) from Japan makes use of the very-low-expansion coefficient of carbon fiber,resulting in a conductor with a lower knee-point of around 70°C (158°F).The core is a resin-matrix composite containing carbon fiber.This composite is capable of withstanding temperatures up to 150°C.The ACFR is about 30% lighter and has an expansion coefficient (above the knee-point) that is 8% that of an ACSR of the same stranding,giving a rating increase of around 50% with no structural work required.
Meanwhile,in the United States,3M has developed the Aluminum Conductor Composite Reinforced (ACCR).The core is an aluminum-matrix composite containing alumina fibers,with the outer layers made from a heat-resistant aluminum alloy.As with the ACFR,the low-expansion coefficient of the core contributes to a fairly low knee-point,allowing the conductor to make full use of the heat resistant alloy within existing sag constraints.Depending on the application,rating increases between 50% and 200% are possible as the conductor can be rated up to 230°C.

目前,所有的新兴的设计都有一个共同点:使用复合材料技术的发展.
铝导体碳纤维增强(ACFR)来自日本利用very-low-expansion系数的碳纤维,导致一个导体与较低的knee-point大约70°C(158°F).核心是一种resin-matrix含碳纤维复合材料.该复合材料能够承受温度高达150℃.ACFR较轻的30%左右,膨胀系数(以上),knee-point 8%的ACSR相同的搁浅,给一个等级增加50%左右的普遍工作要求.
与此同时,在美国,3M公司已经开发出一种铝导体复合增强(ACCR).核心是一种aluminum-matrix含有氧化铝纤维复合材料,外层由一种耐热铝合金.如ACFR系数,low-expansion核心有助于knee-point相当低,使得导体来充分利用现有的凹陷内耐热合金的约束.根据用途,等级增加50% - 200%之间是有可能的,如导线可以增加到230度.
