NLL Strain Clamps Tension Clamps for transmission lines

NLL Strain Clamps Tension Clamps for transmission lines

Suitable for overhead power lines of 35kV and below. It is used to secure aluminum conductors and ACSR (aluminum-conductor steel-reinforced wires), as well as overhead insulated aluminum conductors on tension poles. It can be fitted with an insulating protective cover for insulation protection.

Model: NLL Series

Materials: Aluminum Alloy

Rated Failure Load: 40KN-120KN

NLL Series Bolt-Type Aluminum Alloy Strain Clamp

Suitable for overhead power lines of 35kV and below. It is used to secure aluminum conductors and ACSR (aluminum-conductor steel-reinforced wires), as well as overhead insulated aluminum conductors on tension poles. It can be fitted with an insulating protective cover for insulation protection.

Specifications

The NLL aluminum alloy strain clamp, also known as an NLL dead end clamp, is designed to secure conductors in overhead power distribution lines. Made from aluminum alloy, it provides a practical solution for conductor tensioning and dead-end connections.

NLL strain clamps are available in different models to accommodate various conductor sizes and installation requirements. They are suitable for overhead power line projects where reliable conductor gripping and secure mechanical connections are required.

Key Specifications
