Usage Guidelines

Installation Warning

Safety Distance: ≥3m from Buildings, ≥4.5m above Ground (Road)
Grounding Requirements: Independent Grounding Electrode Resistance <10Ω, Grounding Wire Cross-Sectional Area ≥25mm²

Troubleshooting Guide

Phenomenon	Possible Cause	Emergency Measures
Abnormal humming	Loose core	Tighten bolts during power outage
Oil temperature > 85℃	Overload/poor heat dissipation	Forced air cooling + load reduction
Bushing flashover	Dirt accumulation	Live cleaning (certification required)
