GB/T 31489.1-2015
ActiveDC extruded cable systems for power transmission at a rated voltage up to and including 500kV―Part 1: Test methods and requirements
额定电压500kV及以下直流输电用挤包绝缘电力电缆系统 第1部分：试验方法和要求
Application Summary AI generated
This standard specifies test methods and performance requirements for DC extruded cable systems rated up to 500 kV, including cables, accessories, and their assembled systems. It is applied in high-voltage direct current (HVDC) power transmission projects, such as long-distance submarine or underground cable links, to ensure electrical, mechanical, and thermal reliability under DC voltage stress. The standard is used by manufacturers and testing laboratories for type approval, routine, and sample tests to verify system integrity before installation.
