The H05BQ-F Cable boasts high flexibility and resistance to mechanical loads. Its conductor uses flexible copper wire, and the insulation and sheath materials are made of weather-resistant and chemically resistant rubber and PUR materials. It has stable and reliable performance, and is oil-resistant, abrasion-resistant, and cold-resistant. It is suitable for 300/500 V low-voltage connections, power supply, and control applications, making it an ideal choice for industrial, building, and general equipment interfaces.
