Our forged end accessories are high-strength, precision-engineered
components designed for galvanized steel composite insulators,
ensuring reliable performance in overhead transmission lines,
substations, and other high-voltage applications. Manufactured
through advanced forging techniques and hot-dip galvanization,
these accessories deliver exceptional corrosion resistance,
mechanical durability, and long-term stability even in harsh
environments.
Key Features :
- Premium Material : Forged from high-grade steel for superior tensile strength and
fatigue resistance.
- Corrosion Protection : Hot-dip galvanized coating extends service life in humid,
coastal, or polluted areas.
- Precision Engineering : Tight tolerances ensure seamless compatibility with composite
insulator cores.
- High Load Capacity : Optimized design withstands mechanical stresses (wind, ice,
conductor loads).
- Versatile Applications : Suitable for transmission lines, railways, substations, and
renewable energy projects.

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.
