L-shaped triangular steel plates are core connectors for high-voltage transmission line guying systems. Designed to comply with the national standard (GB), they are specifically developed for securing steel strands, optical cables, and power cables. Handan Jinmai Fastener Manufacturing Co., Ltd., leveraging 20 years of experience in power hardware production, has meticulously calculated triangular mechanical structures to ensure exceptional structural stability in extreme environments. This product is compatible with pre-twisted tension clamps, anti-vibration hammers, and other accessories, and is suitable for 220kV to 500kV transmission and transformation projects.
1. High-Strength Load-Bearing
Forged from Q235B carbon steel, with a tensile strength of ≥500 MPa, it can withstand dynamic loads exceeding 10 tons.
2. Flexible Multiple Holes
6-8 standard bolt holes (Ø16-24 mm) are reserved, allowing for quick assembly with various sizes of connecting plates and clamps.
3. Triple-Effective Corrosion Protection
The surface is hot-dip galvanized (zinc layer ≥86 μm), passivated, and epoxy-coated. Salt spray resistance exceeds 3,000 hours, making it suitable for harsh environments such as coastal areas and industrial pollution zones.
1. Precision Forging
Hydraulic forging technology based on CAD/CAM modeling ensures accuracy within ±0.5mm.
2. Laser Calibration
Utilizing a fiber laser cutting system, we ensure hole concentricity of ≤0.1mm, minimizing stress concentration.
3. Full-Process Quality Inspection
ISO 9001 certified, each batch undergoes tensile testing, metallographic analysis, and zinc coating adhesion testing.
