产品名称：RXG(T)被漆线绕可调电阻器
Product name: RXG(T)Adjustable silicon cemented wite wound resistors

型    号：RXG(T)
Type:   RXG(T)

产品介绍：RXG型涂料绕线电阻器其表面覆盖了具有阻燃，耐高温特性的涂料，性能可靠，使用方便等特点。电阻分为固定式或可调式，可调式可左右移动。固定式有两个或多个电阻脚，电阻脚厚度可根据功率大小调节。
Product introduction: RXG series cement-coated wire wound resistor is covered with dope which has inflammability and can resistance to high temperature, it has the characteristic of good ability and easy to use. The resistor can be classed to settled form and adjustive form, and the adjustive form can move right-and-left. The settled form has two or more terminals, its thickness can adjust accord to power.

用    途：涂料绕线电阻广泛用于变频器制动，电梯，起重机械以及负载电阻之用。
Purpose:  Cement-coated wire wound resistor is used in transducer trig, elevator, derrick and as load resistor widely.
