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 fa
