线规尺寸

什么是 线规的定义?

Wire/cable thickness is defined in terms of gauge.  Generally speaking,  the smaller the gauge number, the thicker the cable.  The standardized method of measuring the thickness of a cable (American Wire Gauge or AWG) was established in 1857 in the United States.  This form of measuring cable thickness is used specifically for electrically conductive wire.  Note that the diameter of the cable does not include the outer insulation - just the conducting wire on the inside.

线规术语

  • “gauge(线规)”这个术语用于1 AWG以下的导线
  • The term “aught” (zero) is used for wire 1/0 AWG and larger.  The number "0" in the size is "aught"
