Products Description

1. Gapless Protection Performance Breakthrough
The 27kV gapless porcelain-housed metal-oxide surge arrester realizes zero-delay overvoltage suppression with its advanced gapless design. The high-purity metal-oxide varistors ensure ultra-sensitive response to transient surges, clamping abnormal voltages to safe levels in milliseconds to avoid equipment damage.
2. Premium Material & Structural Durability
Adopting high-strength alumina porcelain housing and corrosion-resistant internal components, this arrester boasts excellent mechanical strength and electrical insulation. It resists harsh environmental factors like salt fog, dust, and extreme temperature changes, maintaining stable performance for over 25 years.
3. Energy-Saving & Low-Maintenance Advantages
With ultra-low leakage current (≤5μA) during normal operation, the arrester achieves remarkable energy-saving effects. Its gapless structure eliminates the need for regular gap inspection and adjustment, reducing maintenance workload and long-term operational costs significantly.
4. Wide Application & Grid Compatibility
Designed for 27kV power systems, this arrester is widely applicable in substations, industrial distribution networks, and overhead transmission lines. It perfectly matches various power equipment, providing reliable overvoltage protection and enhancing overall grid stability.
5. Safety & Compliance Assurance
The arrester complies with international IEC standards and domestic electrical industry specifications, undergoing strict type tests and quality inspections. Its stable performance and reliable protection capability ensure the safe operation of power systems and reduce the risk of power outages.
