Rebar Grounding Clamps of Bronze
Rebar Grounding Clamps of Bronze
We are an Indian Bronze and Copper foundry manufacturing and exporting high-quality Rebar Grounding Clamps of Bronze for electrical grounding and bonding applications. Our bronze rebar grounding clamps are engineered to provide a secure, low-resistance connection between grounding conductors and concrete-encased electrodes (rebar), making them an essential component in modern electrical grounding systems.
Manufactured from high-strength electrolytic bronze alloy, our rebar grounding clamps deliver excellent corrosion resistance, superior conductivity, and long-term durability — even in the most demanding direct burial and concrete-encased environments. They are widely used in commercial, industrial, and infrastructure projects worldwide.
What Are Bronze Rebar Grounding Clamps?
A bronze rebar grounding clamp is a specialized electrical connector designed to bond a copper grounding conductor (wire/cable) directly to a steel reinforcement bar (rebar) embedded in concrete. Concrete-encased rebar used in building foundations serves as an effective grounding electrode as recognized by the National Electrical Code (NEC). The clamp ensures a mechanically strong and electrically continuous connection between the conductor and the rebar electrode.
Our clamps are cast and machined from high-grade bronze alloy, providing an optimal combination of strength, electrical conductivity, and resistance to the alkaline environment inside concrete. They are designed to accommodate a wide range of conductor and rebar sizes, making them versatile and suitable for diverse project requirements.
Key Features
- Dual Connection Points: Provides two conductor connection points to the concrete-encased rebar electrode, meeting the requirements of jurisdictions where the Authority Having Jurisdiction (AHJ) mandates dual bonding connections.
- NEC Compliant: Meets NEC standard requirements for bonding conductors to rebar as part of the grounding electrode system.
- High-Strength Bronze Alloy Construction: Cast from premium electrolytic bronze for exceptional mechanical strength and reliable long-term electrical performance.
- Direct Burial & Concrete Encased: Fully suitable for direct burial and concrete-encased electrode applications without degradation.
- Wide Conductor & Rebar Range: Accommodates conductor sizes from #8 Solid to 4/0 Stranded (10 mm² to 100 mm² Stranded) and rebar sizes #6 through #11 (20M–35M Canadian standard).
- Easy Installation: Simple bolt-tightening design ensures fast and reliable field installation with standard tools.
- Stainless Steel Hardware Option: Available with Stainless Steel A2 AISI 304 fasteners for additional corrosion resistance in aggressive environments.
- UL 467 Compliant: Manufactured to meet UL 467 grounding and bonding equipment standards.
