Model NO. | DC rod-shaped post porcelain insulator |
Rated voltage | 24kV |
Rated frequency | 50/60Hz |
Series | ZCW |
DC rod-shaped post porcelain insulators are specialized components designed for direct current (DC) power systems, serving as critical elements that provide both mechanical support and electrical insulation. They are primarily used to secure and insulate conductors, busbars, or other live parts in DC substations, transmission lines, and industrial DC equipment, preventing current leakage to grounded structures and ensuring stable, safe operation of high-voltage DC networks.
DC-Specific Insulation Performance: Optimized for direct current environments, with enhanced resistance to polarization and electrochemical corrosion, ensuring reliable insulation under steady DC voltage.
Robust Structural Support: The rod-shaped post design offers strong mechanical stability, capable of withstanding conductor tension, vibration, and external loads to keep components securely positioned.
High-Quality Porcelain Construction: Made from dense, high-purity porcelain material, providing excellent dielectric strength and resistance to electrical breakdown even in harsh conditions.
Environmental Durability: Resistant to extreme temperatures, humidity, UV radiation, and industrial pollution, maintaining performance in both indoor and outdoor DC power applications.
Compatibility with DC Systems: Engineered to integrate seamlessly with DC transmission and distribution setups, supporting the specific voltage and current requirements of DC networks.
