Type: ECR-glass Epoxy Rod (ECR Rod) Main Features: ECR rod has all performances that FRP Rod has, but also has extra good stress-corrosion resistant performance as well as high temperature resistance. 1. Pultrusion technology 2. Diameter: 6mm to 130mm; length according to requirements. 3. Superior mechanical strength, corrosion resistance and flame resistance. 4. Excellent electrical insulation performance. 5. IEC, ASTM, GB Standards.
Application reference: Diameter 16--38mm for composite tension & suspension insulators Diameter 22--54mm for composite pin insulators Diameter 24--80mm for composite line post insulators Diameter 28-130mm for composite station post insulators Diameter 20--36mm for composite fuse cutout (insulators) Technical Specifications (Φ18mm ECR Rod Sample) No. | Description | Unit | Value | 1 | Density (20±2℃) | g/cm3 | ≥2.0 | 2 | Water Absorption Rate | % | ≤0.05 | 3 | Tensile Strength | MPa | ≥1200 | 4 | Bending Strength | MPa | ≥900 | 5 | Torsion Strength | N/mm2 | ≥90 | 6 | Compressive Strength | MPa | ≥590 | 7 | Thermal Bending Strength | MPa | ≥300 | 8 | Dye Penetration Test | Min | ≥15 | 9 | Volume Resistant Test (140℃, 96h) | Ω·m | ≥1010 | 10 | Water Diffusion Test 0.1%NaCl, 100h, 12kV, 1 min. | mA | ≤0.03 | 11 | D.C Puncture Voltage Test | kV | ≥50 | 12 | Dry Lightning Impulse Withstand Voltage Test (1.22/50.8 us; ≥100kV) | Withstand Times | ≥5 | 13 | Heat Deflection Temperature | ℃ | ≥155 | 14 | Stress Corrosion Test | h | ≥96 |
