Hot Dip Galvanized Transmission Tower Link Fittings are essential hardware components used in overhead power transmission lines, substation structures, and telecommunication towers.
These link fittings provide secure mechanical connections between tower members, insulators, conductors, and grounding systems, ensuring structural integrity and long term reliability under extreme environmental conditions.
Manufactured from high strength low carbon steel and protected by a hot dip galvanized coating, these fittings offer superior corrosion resistance, mechanical strength, and weather durability — making them ideal for utility projects, renewable energy installations, and industrial power distribution networks.
| Feature | Description |
|---|---|
| Hot Dip Galvanized Finish | Uniform zinc coating (70–100 µm thickness) provides 30+ years corrosion protection in most environments |
| High Mechanical Strength | Manufactured from Grade 4.6, 6.8, or 8.8 steel to withstand tensile loads, shear forces, and vibration |
| Standardized Dimensions | Designed to meet IEC, ANSI, ASTM, BS, DIN, and GB standards for international compatibility |
| Wide Range of Types | Link plates, chain links, clevis links, eye links, turnbuckle links, anchor links, extension links |
| Easy Installation | Pre drilled holes with standard bolt diameters (M12, M16, M20, M24, M30) for quick bolted connections |
| Full Traceability | Each fitting is stamped with grade mark, size, and batch number for quality assurance |
| Type | Description | Application |
|---|---|---|
| Link Plate | Flat, bent, or offset plates | Bracing, cross arm connections |
| Chain Link | Welded or forged links | Insulator attachments, grounding connections |
| Clevis Link | With pin or bolt | Connecting insulator strings to tower |
| Eye Link | Round or slotted | Anchor points, suspension connections |
| Turnbuckle Link | Adjustable length | Tension adjustment, guy wire connections |
| Anchor Link | Dead end connections | Tower anchoring, foundation connections |
| Extension Link | Spacer and offset applications | Length adjustment, clearance management |
