Short Description
Standard: Meets IEC 61284 and GB/T 2314 standards.
Body Material: High-strength, anti-corrosion Aluminum Alloy (A356/A380).
Hardware: Hot-dip Galvanized Steel (HDG) U-bolts, nuts, and spring washers.
Usage: Designed for dead-ending and anchoring ACSR, AAC, and AAAC conductors on distribution lines up to 35kV.
Key Advantage: The unique pistol-angle body provides easier installation and superior grip without damaging the conductor.
Detailed Description
Introduction:
The NLL-P Series Pistol Type Strain Clamp is specifically engineered for overhead power lines where a secure, non-slip termination is required. Unlike standard straight clamps, the pistol-shaped body allows for a more natural angle during tensioning, reducing mechanical stress on the pole-top hardware.
Core Features & Benefits:
- Energy Saving: The non-magnetic aluminum alloy body eliminates hysteresis loss (eddy current loss), significantly reducing power wastage on the line.
- Superior Durability: The cast aluminum body offers excellent resistance to atmospheric corrosion, making it ideal for coastal and industrial environments.
- High Tensile Strength: The multi-U-bolt design ensures a grip strength of at least 95% of the conductor’s rated breaking strength (RBS).
- Gentle on Conductors: Smooth cable grooves and radius-controlled bends prevent “bird-caging” or strand damage during high-tension periods.
