NLL Bolt Type Aluminum Alloy Strain Clamp
Category: Power Fittings
NLL bolt type strain clamp is tension power fitting for overhead lines. It is mainly used for terminal fixing and tension connection of overhead aluminum conductors and ACSR wires. Conductors are compressed by bolts. It features high mechanical strength and easy installation, widely used in power distribution and transmission lines.
Specifications
| Material | The main body is high-strength aluminum alloy with good conductivity; fasteners are hot-dip galvanized carbon steel for rust resistance and outdoor service. |
| Structure | Composed of aluminum alloy clamp body, U-shaped pressing blocks, bolts, nuts and cotter pins. The arc grooves inside the clamp fit the outer circle of conductors. Tighten bolts to compress wires to transmit mechanical tension and electric power. Cotter pins lock nuts to avoid loosening caused by vibration. |
