저항기의 구조는 절연강도내압이 좋은 절연체 위에
저항선을 감은후 불연성 도료로 도포하여 내열성이
우수하므로 고전력이 요구되는 산업용기기에 적합
합니다.

RWH type resistor is optimum for industrial and high-power
instruments from 20w to 2kw.
The structure of RWH type resistor is that nickel-chrome
wire is wound on aninsulator that has good insulation,
strenght and withstanding voltage and, it is coverd with
glaze.

When Loading for a short time with a cycle of over 30 minutes, the load can be more than the rated power. To avoid short circuits between cables, do not exceed the maximum capable voltage between terminals.
