波纹绕线电阻器
波纹电阻器 Wire Wound Resistor
产品描述（Product Profile）
波纹绕线电阻在圆柱形的陶瓷管上固定了两个引出端子，瓷管表面上缠绕了扁带波浪形状的合金电阻丝，并在其表面涂覆有一层具有阻燃、耐高温的涂层。陶瓷管作为电阻丝骨架的同时，又具有散热器的功效。本品可以按照客户要求定制。广泛用于模拟负荷试验，设备放电，自动控制，变频器能耗制动等。
Two terminal extensions are fixed on both ends of a ceramic tube on whose surface winds wave-shaped alloy resistance wire and a high temperature-resistant and fireproof coating are applied. The ceramic tube can function as resistance wire skeleton and heat radiator as well. This product can be customized to special needs of customers and applicable to simulation load test, equipment discharge, automated control and inverter's loss brake.
