Corrugated Waveguide Termination

Corrugated resistors, also known as wire-wound power resistors or braking resistors, are industrial components specifically designed to **consume high-power electrical energy and enable rapid heat dissipation**. Their core function is to convert excess electrical energy in a circuit—particularly the regenerative energy generated during motor braking—into heat and release it, thereby **safeguarding main equipment such as frequency converters and servo systems**.

Product Introduction

It is an "energy discharge valve" born for high-energy consumption industrial scenarios. Through its physical design of corrugated vertical winding, it prioritizes ensuring exceptional heat dissipation capability, low inductance, and high reliability even under harsh conditions involving high parasitic inductance, significant mechanical stress, and extreme thermal cycling. Its high-temperature resistance is the foundation of its normal operation, not a flaw.
