Short answer: overhead line fitting models should be indexed by function, conductor size, mechanical load, fitting interface, material and hot-dip galvanizing requirement.
| Suspension fittings | Support conductors or insulator strings. Confirm conductor diameter, angle and clamp type. |
|---|---|
| Tension fittings | Carry tensile load at dead-end or strain points. Confirm breaking load and conductor grip. |
| Guy fittings | Used for pole stability. Confirm guy wire size, anchor interface and load rating. |
| Connecting fittings | Shackles, clevises, yoke plates and links must match hole size, pin size and load class. |
Overhead fittings should not be selected only from a photo. Load class and connection dimensions must be confirmed.
