Composite Insulator Rod

Insulator Rod Features: 1) High quality 2) Reasonable price

Insulator Rod is widely used in composite insulators of silicone rubber, posts, cross arms, drop switches, disconnecting switches and electric railway posts. We can produce epoxy fiber glass rods with diameter from 2 to 4mm to be used in optical cables. Features: 1) Core rods length: according to customers' requirements2) No crack fault trace3) Don't allow gum deposit4) Colors: light yellow or light green which is uniform5) Can be used with saw, mill, knife plane, drill, lathe and grinder for machiningSpecifications: 1) Length tolerance: ≤±1mm2) Nominal diameter: 2 - 9mm, 10 - 18mm, 20 - 28mm, 30 - 40mm, 41 - 130mm3) Nominal deviation: ±0.15mm, ±0.1mm, ±0.3mm, ±0.3mm, ±0.4mm4) Density: ≥2.2 or 2.0g/cm³5) Water absorption: a) General: 0.02%b) Acid resistance: 0.05%6) Tensile strength: a) General: 1,680MPab) Acid resistance: 1,326MPa7) Flexural strength: a) General: 965MPab) Acid resistance: 900MPa8) Hot flexural strength: a) General: ≥300MPa/150°Cb) Acid resistance: 260MPa/150°C9) Fuchsine test: >20min10) Water diffusion test: ≤0.03mA11) Compressive strength: a) General: 965MPab) Acid resistance: 912MPa12) Fiber content: ≥75%13) Interlaminar shear strength: a) General: ≥65MPab) Acid resistance: ≥58MPa14) Industrial frequency break voltage: ≥50kV/cm15) Full wave impulse voltage: a) General: ≥95kV/cmb) Acid resistance:≥94.5kV/cm16) Stress corrosion: ≥96h
