resistance wire

基本解释

A copper-nickel alloy with high electrical resistance and a low temperature coefficient; used as resistance wire.
一种铜镍合金，电阻大和温度系数低，用作电阻丝。
Sliding head D can slide along the metal bars, with good contact resistance wire, changing its location can change the AC (or BC) resistance.
滑动头D可沿金属杆滑动，与电阻丝接触良好，改变其位置就可以改变AC（或BC）电阻。
Two terminal extensions are fixd on both ends of a ceramic tube on whose surface winds wave-shapcd alloy resistance wire and a high temperature-resistant and fireproof coating are applied.
在圆柱形的瓷管上固定了两个引出端子，陶瓷管表面上缠绕了扁带波浪形状的合金电阻丝，并在其表面涂覆一层具有阻燃，耐高温特性的涂层。
