Our C1100 earthing copper strips represent premium quality in copper grounding solutions, engineered for exceptional conductivity and reliability. Crafted from high-purity C1100 copper, these strips deliver superior electrical performance, ensuring efficient dissipation of electrical charges—critical for safety in power systems, industrial facilities, and construction projects. The premium-grade material offers excellent corrosion resistance, maintaining long-term functionality even in harsh environments. With precise dimensions and smooth surfaces, they facilitate easy installation, whether through welding, bolting, or clamping. As a trusted copper product, these earthing strips meet strict quality standards, providing consistent performance to protect equipment and infrastructure from electrical faults, making them an essential choice for reliable grounding applications.
The inner and outer surfaces are highly clean and bright,the structure is uniform and dense,the dimensional accuracy is high, and the formability is good.
I. High-Purity C1100 Copper: Foundation of Premium Performance
C1100 is a high-purity oxygen-free copper grade (compliant with standards like ASTM B152/B152M or GB/T 2059), with a copper content of ≥99.90%—the key to its superior performance in earthing applications:
Minimal Impurities: Low levels of trace elements (e.g., iron, lead, sulfur ≤0.005%) eliminate "electrical resistance hotspots" in the material. Unlike lower-grade copper (e.g., C1020 with ~99.85% purity), C1100 ensures uniform current flow, avoiding localized overheating or grounding failure.
Inherent Ductility & Malleability: Premium C1100 copper retains excellent ductility (elongation ≥30%) and malleability, even after processing into strips. This allows the strips to be bent, twisted, or shaped on-site (e.g., around concrete structures, pipes) without cracking—critical for adapting to complex grounding layouts.
Stable Physical Properties: Resists brittle deformation at extreme temperatures (operating range: -200°C to 250°C), maintaining structural integrity in harsh environments (e.g., cold winters, high-temperature industrial workshops).
II. Excellent Electrical Conductivity: Core for Effective Earthing
Earthing systems rely on low electrical resistance to safely divert fault currents (e.g., short circuits, lightning strikes) to the ground. C1100 copper strips excel in this aspect:
Low Electrical Resistance: C1100 copper has a conductivity rating of ≥100% IACS (International Annealed Copper Standard) at 20°C—far higher than aluminum (61% IACS) or copper alloys (e.g., brass: ~28% IACS). For a standard 3mm-thick × 30mm-wide C1100 strip, the DC resistance is as low as 0.0005 Ω/m, ensuring rapid, efficient current dissipation.
Uniform Current Distribution: The flat strip shape provides a larger cross-sectional area and surface contact with the ground compared to round copper wires. This reduces "current crowding" (a common issue in narrow conductors) and ensures fault currents are dispersed evenly, preventing damage to electrical equipment or wiring.
Lightning & Surge Protection: In lightning protection systems, the high conductivity of C1100 strips enables them to absorb and divert large transient currents (up to tens of kiloamperes) in milliseconds, protecting buildings, power transformers, and sensitive electronics from surge damage.
