Product Description

The NLL-3 Bolted Type Strain Clamp is a high-strength anchoring solution designed for overhead distribution lines. Made from premium-grade aluminum alloy, it is specifically engineered to secure ACSR, AAC, and AAAC conductors without causing damage to the wire strands.

Featuring a heavy-duty 3-bolt configuration, the NLL-3 provides superior mechanical grip and electrical connectivity. Its non-magnetic body eliminates hysteresis loss, ensuring high energy efficiency for power utilities. This clamp is an ideal choice for tension towers and terminal poles in harsh environments, offering long-term durability and resistance to atmospheric corrosion.

Why Choose our NLL-3?

• 3-Bolt Heavy Duty Design: Specifically engineered for 120mm² – 150mm² ACSR, providing a longer clamping surface and higher slip strength than the NLL-2.
• Direct from Yongnian Factory: Benefit from the world’s largest fastener hub. We offer the most competitive wholesale prices for private projects in Africa and Southeast Asia.
• Zero-Tool Installation: No hydraulic press needed—just a standard wrench. This is a game-changer for remote rural electrification where heavy machinery is unavailable.
• Corrosion Resistance: High-strength aluminum alloy body stands up to tropical humidity and harsh environments.
