Why settle for 3-prong rods when 4-anchor systems deliver 62% better stability? Our cọc nối đất 4 chân features:
Feature | 3-Prong | 4-Prong |
---|---|---|
Resistance (Ω) | ≥15 | ≤5 |
Lifespan | 8-10 years | 15+ years |
Our thanh nối đất bằng đồng 4 chân uses 99.9% pure copper - 3X more conductive than galvanized steel. Tested to withstand 200kA lightning strikes (IEC 62305 certified). Competitors' rods? Most fail at 80kA.
Red soil? Coastal site? Our modular cọc nối đất systems adapt. Choose from 1.5m to 6m lengths. Need hybrid configurations? We'll engineer them in 72 hours.
A Da Nang telecom tower cut downtime 94% using our rods. A Ho Chi Minh factory eliminated $280k/year in equipment damage. Your success could be next.

A: A 4-legged grounding rod provides stable electrical grounding by distributing current across four electrodes. It’s ideal for high-resistance soil or critical infrastructure. This design enhances safety and reduces resistance.
A: A 3-legged grounding rod has fewer electrodes, making it lighter and cheaper but less effective in high-resistance environments. The 4-legged version offers better stability and conductivity for demanding applications.
A: Copper’s high conductivity and corrosion resistance improve grounding efficiency. The 4-legged design ensures even current distribution, making it perfect for industrial or sensitive electronic systems.
A: Yes, but it may require specialized installation techniques like pre-drilling or chemical backfill. The 4-legged design helps overcome soil resistance by spreading the grounding load.
A: Most 4-legged copper grounding rods meet standards like IEC 62561 or IEEE 80. Always verify certifications for corrosion resistance and conductivity to ensure compliance.
