Leading Overhead Line Fittings Manufacturer: Engineering Excellence for Global Power Grids
As a premier Overhead Line Fittings Manufacturer, we specialize in the design and production of critical hardware for electrical distribution and transmission networks. Our products are engineered to withstand the mechanical and electrical stresses of 11 kV to 765 kV systems, ensuring the integrity of overhead lines (OHL) in the most demanding environments across India and globally.
All our fittings are manufactured in our ISO 9001:2015 certified facility and strictly adhere to IS 2486, IS 2121, and IEC 61284 standards.
Our Core Product Categories (OHL Catalog)
To meet the diverse needs of utility engineers, our product line is divided into specialized categories of OHL fittings.
1. Suspension & Tension Fittings
The mechanical heart of the transmission line.
- Suspension Clamps (Envelope & Trunnion Type): Designed to support conductor weight while protecting against fatigue at the attachment point.
- Compression Tension Clamps: Forged aluminum and steel sleeves providing more than 95% UTS for high-voltage dead-ending.
- Wedge Type Clamps: Used for rapid and secure conductor termination.
2. Insulator Hardware & String Fittings
Ensuring the secure connection between tower and conductor.
- Ball & Socket Fittings: Manufactured to IEC 60383 dimensions for global compatibility.
- Clevis & Tongue Connectors: Forged for high-tensile reliability in tension strings.
- Yoke Plates: Used for bundled conductors such as Twin, Quad, and Hexa.
3. Protection & Damping Accessories
Extending conductor life through advanced energy dissipation.
- Stockbridge Vibration Dampers: Reduce Aeolian vibration using multi-resonance designs.
- Corona & Grading Rings: Essential for EHV lines above 220 kV to control electrical discharge and RIV.
- Arcing Horns: Provide a sacrificial path for surge protection of insulator strings.
