Jiujin Electric Power’s Parallel Groove JBB Clamp is engineered to create durable and electrically efficient connections between parallel wires in overhead power lines. Fabricated from high-quality steel and finished with a heavy-duty hot-dip galvanized coating, this clamp offers superior protection against rust, corrosion, and environmental wear. The parallel groove design distributes pressure evenly across the conductors, minimizing contact resistance and preventing overheating. Its simple yet robust construction allows for easy installation with standard tools, reducing labor time while ensuring long-term performance. Manufactured in our Hebei facility under strict quality control, this clamp meets international standards for electrical safety and reliability in distribution and transmission networks.
