Product Description

Specification

Product Description:
The NLL-Type Strain Clamp is a heavy-duty aluminum alloy or forged steel dead-end clamp designed for overhead transmission lines and distribution networks. It provides secure anchoring for conductors (ACSR, AAAC, or AAC cables) while maintaining mechanical strength and electrical conductivity.

Key Features:
- High Tensile Strength – Supports load capacities from 30kN to 200kN
- Corrosion-Resistant – Hot-dip galvanized or anodized finish (IEC 61284 compliant)
- Easy Installation – Bolted or wedge-type design for quick field assembly
- Thermal Stability – Suitable for operating temps -40°C to +80°C
- Low Resistance – Ensures minimal power loss in HV applications

Applications:
- Transmission lines: Dead-end termination for conductors
- Substations: Busbar anchoring
- Renewable energy: Solar/Wind farm grid connections
- Railway catenary systems: Overhead line support
