Technical Edge: 4-Prong vs 3-Prong Grounding
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 |
Manufacturer Showdown: Copper Matters
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.

FAQS on cọc nối đất 4 chân
Q: What is a 4-legged grounding rod (cọc nối đất 4 chân) used for?
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.
Q: How does a 3-legged grounding rod (cọc nối đất 3 chân) differ from a 4-legged one?
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.
Q: Why choose a 4-legged copper grounding rod (thanh nối đất bằng đồng 4 chân)?
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.
Q: Can a 4-legged grounding rod be installed in rocky soil?
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.
Q: Are 4-legged copper grounding rods compliant with international standards?
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.
