Lightning arresters are critical for safeguarding electrical infrastructure from surges and strikes. However, even robust systems like Zinc oxide lightning arresters can face issues. Here’s how to address common faults and ensure reliable surge protection.

When operating critical electrical systems, the performance of High-voltage isolation switches, Disconnect switches, and Electrical isolator switches directly impacts safety and efficiency. Regular inspections and prompt troubleshooting are essential to prevent costly downtime. Here are three common issues and solutions to keep your equipment running smoothly.

Installing high-voltage through-wall conduits demands strict adherence to safety and electrical codes. Follow these critical steps to avoid risks like fires, equipment damage, or code violations

Ensure zinc oxide arresters (ZnO) in high-voltage systems perform optimally with proactive care: monitor leakage current (<1mA), inspect for pollution/cracks, and use thermal imaging to detect hotspots. Compliant with IEC 60099-4 & IEEE C62.11. Prevent equipment damage, fires, and fines—schedule professional testing today.

Oil-immersed high-voltage metering cabinets deliver precise, durable power measurement for 10kV-35kV grids in extreme environments (-40°C to +80°C). Featuring hermetically sealed, corrosion-resistant designs with insulating oil, these IEC 61869-compliant units ensure moisture-proof operation, low maintenance, and ±0.2% accuracy—ideal for substations, industrial plants, and renewable energy sites. Customizable configurations (CT/PT integration, explosion-proof) , offering reliable solutions for harsh conditions like coastal or high-humidity areas.

Zinc Oxide (ZnO) surge arresters, with their nonlinear resistance properties and superior performance, are the preferred solution for modern overvoltage protection.Widely adopted in power systems, renewables, and industrial facilities, ZnO arresters deliver cost-effective, durable protection against electrical surges.
