Product application :
These high-strength forged end fittings are critical components designed for use with galvanized steel composite insulators in various electrical and infrastructure applications. Their robust construction and corrosion-resistant properties make them ideal for:
1. Overhead Transmission & Distribution Lines
- Used as suspension clamps, tension clamps, or ball-eye connections in high-voltage power lines (AC/DC systems).
- Suitable for extra-high voltage (EHV) lines (up to 1,100kV) due to their mechanical reliability.
2. Substations & Switchgear
- Connect composite insulators to busbars, circuit breakers, or disconnect switches.
- Ensure stable grounding and isolation in harsh environments.
3. Railway Electrification Systems
- Secure catenary wires and overhead line equipment (OLE) for high-speed rail and metro systems.
- Withstand vibrations and dynamic loads from passing trains.
4. Renewable Energy Projects
- Wind farms: Support offshore/onshore wind turbine earthing systems.
- Solar plants: Used in solar tracker installations and substation linkages.
5. Industrial & Harsh Environments
- Chemical plants, mining sites, and coastal areas where corrosion resistance is critical.
- Telecom towers and lightning protection systems.
Key Advantages for These Applications :
✔ Longevity: Galvanization prevents rust in humid/coastal climates.
✔ Safety: High load capacity reduces risk of mechanical failure.
✔ Compatibility: Matches global standards (IEC, ANSI, etc.) for seamless integration.
