3. ‌NH-WDZ-YJGFP22-3KV 4 * 4 rotor high insulation cableApplication scenarios

• Mainly used for generator rotor grounding protection system and excitation system secondary control circuit

• High voltage power transmission suitable for industries such as electricity, petrochemicals, metallurgy, etc

• Excitation cable is a DC cable used as a power supply lead wire in electrostatic spray painting, electrostatic beneficiation, electrostatic flocking, and other low current and high voltage DC devices. The general structure of a DC cable consists of a core, inner insulation layer, semiconductor layer, steel armor, filling material, outer insulation layer, etc. The materials used for cables with different purposes are different, but the cores are all copper or aluminum. Currently, aluminum is more commonly used

• For transmission in power plants and power lines,

• High insulation cables have advantages such as heat-resistant mechanical properties, good electrical performance, and chemical corrosion resistance, and are therefore widely used in enterprises such as power, petrochemical, and metallurgical industries.

• Product execution standards

• HQ/TJC2008-06

• The standard flame retardant characteristic test shall comply with GB1706-8-2020 standard.
