Applications
The ED-2B shackle insulator is primarily used in low-voltage overhead distribution lines, including:
- Terminal poles
- Corner poles
- Tension poles
- Secondary racks
- Overhead service connections
It is mounted on a spindle, bolt, or bracket, and the conductor is secured using soft-bending tie wire. The brown porcelain glaze offers excellent weathering resistance for long-term outdoor service.
Installation Notes
- Mount the insulator securely on the pole bracket, spindle, or bolt.
- Secure the conductor using suitable tie wire.
- Ensure correct alignment to maintain mechanical and electrical performance.
- Inspect for cracks or glaze damage before installation.
- Follow local utility installation guidelines.
