JUNW GB1 Insulated Dead End Clamp for Multi-Conductor Lines

JUNW GB1 Insulating Dead End Clamp
1. Multi-Conductor Tensioning for Overhead Distribution
The JUNW GB1 is purpose-built for tensioning multi-conductor overhead lines, supporting 4×(35–50mm²) conductors with a 11–14mm messenger diameter and a robust 15kN breaking load. It is ideal for three-phase four-wire or multi-circuit distribution lines, providing reliable terminal tension fixation for commercial, industrial, and rural power networks with multi-core overhead configurations.
2. Reinforced Bolt-Tensioned Structure for Secure Grip
Featuring a heavy-duty galvanized steel framework and bolt-tensioned clamping mechanism, the GB1 distributes uniform pressure across all conductors, eliminating strand damage or slippage. Its serrated, multi-contact jaws lock firmly onto insulated wires, maintaining consistent tension even under wind vibration, thermal cycling, or heavy load fluctuations.
3. Weather-Resistant Insulation & Corrosion Protection
The integrated UV-stabilized polymer insulation housing provides full electrical isolation and anti-aging performance, resisting harsh outdoor conditions including rain, UV exposure, and coastal salt spray. Galvanized metal components prevent rust and degradation, ensuring long-term reliability in high-pollution or humid environments.
4. Streamlined Installation & Low-Maintenance Operation
Designed for stripping-free, tool-assisted installation, the GB1 mounts quickly to standard pole or wall hardware using common hand tools. Its maintenance-free construction eliminates the need for periodic retightening, reducing operational costs and downtime for remote or hard-to-access multi-conductor overhead lines.
