Abubuwa

• Wide Voltage Range Compatibility：Covers 6kV to 220kV systems, with rated voltages precisely matched to diverse medium - high voltage grid needs. Adapts to both distribution and sub - transmission networks, providing uniform surge protection across multiple voltage classes.

• Composite Housing Advantages：The composite (silicone rubber) enclosure offers superior performance: excellent hydrophobicity resists pollution and moisture, reducing flashover risks; high mechanical strength withstands wind, seismic forces, and thermal cycles; lightweight design simplifies installation vs. traditional porcelain, cutting labor and transport costs.

• Post - type Structural Design:Vertical post - type layout enables space - efficient installation in substations, aligning with standard insulator/post mounting configurations. Simplifies integration into existing grid setups, reducing spatial requirements and facilitating maintenance access.

• Low Maintenance & Long Lifespan:Composite housing resists aging, UV degradation, and chemical corrosion, lowering maintenance frequency. Built - in thermal stability and MOV self - healing properties (to an extent) extend service life, ensuring reliable protection for 15 + years with minimal upkeep.

• Compliance & Safety:Meets international standards (e.g., IEC 60099 - 4, IEEE C62.11) for surge arresters. Undergoes rigorous testing for impulse current withstand, thermal stability, and environmental endurance, guaranteeing safe operation in harsh grid conditions.

• Surge Current Diversion Efficiency:Effectively diverts large surge currents (from lightning/switching) to the ground, limiting overvoltages to levels safe for connected equipment (transformers, cables). Reduces downtime risks and equipment damage, enhancing overall grid resilience.
