Segmented Multi-Chamber Arc-Quenching Surge Arrester (Active Arc-Quenching)
For 6-35 kV overhead distribution lines that need stronger lightning-trip prevention, especially pole-mounted line sections exposed to lightning-induced transient overvoltage, pollution, condensation or severe outdoor service conditions.
What it doesThe segmented multi-chamber arc-quenching surge arrester uses built-in arc-quenching valve plates in each chamber to actively extinguish lightning power-frequency follow-current arcs. It does not require coordination with substation auto-reclosing equipment. The fully enclosed core arc-quenching unit helps protect the device from contamination and condensation, while the resistor-free full-air arc passage increases lightning-current carrying capability and reduces thermal-breakdown risk.
Why buyers choose it- Active arc-quenching design helps significantly reduce lightning-induced tripping on distribution lines.
- Segmented multi-chamber structure creates multi-angle and multi-layer arc breakpoints for reliable arc compression, stretching and extinction.
- Fully enclosed structure improves tolerance to pollution, condensation and harsh outdoor environments.
- Resistor-free full-air dielectric arc channel supports high current carrying capability and low residual voltage performance.
- 10 kV models support live-line installation, reducing outage losses during construction.
- Type-tested product family covers 10 kV and 35 kV models and supports optional discharge counters and remote monitoring devices.
Please confirm voltage class, line type, pole arrangement, installation quantity, altitude, ambient conditions, live-line installation requirement, and whether discharge counters or remote monitoring devices are needed.
