Triangular Yoke Plates Core Advantages
1.Stability of Triangular Structure: Symmetrical distribution of three isosceles holes ensures uniform stress and no eccentric load, providing superior torque and wind vibration resistance compared to straight plates.
2.Complete Load Rating Range: Standard carbon steel and heavy-duty forged steel models are available, with a maximum rated breaking load of 600kN.
3.Reliable Corrosion Resistance: Hot-dip galvanizing conforms to ASTM A153 and GB/T 13912. Standard, zinc coating thickness ≥85μm, strong adhesion
4.High hole precision: High-precision punching, good hole roundness and perpendicularity, precise hole spacing, high compatibility with standard fasteners
5.Comprehensive specification coverage: Full range from light to heavy loads, equilateral and right-angled triangular structures available
Triangular Yoke Plates Load Rating Parameters
| Grade | Rated Load | Reference Weight | Application |
| Light Duty | 70 – 120 kN | 1.8 – 6.5 kg | Medium-voltage transmission lines, low-load suspension points |
| Medium Duty | 160 – 300 kN | 6.9 – 16 kg | 110kV – 220kV high-voltage transmission lines |
| Heavy Duty | 400 – 600 kN | 17.4 – 23.3 kg | 330kV – 500kV+ EHV/UHV transmission lines |
