Product Description:
The Epoxy Glass Laminated Sheet is a high-performance industrial laminated sheet. It is manufactured by hot-pressing chemically treated non-alkali glass fiber cloth impregnated with high-Tg epoxy resin, making it a Class H heat-resistant insulating material. This product features high mechanical strength at elevated temperatures and stable electrical properties under high humidity conditions, and is widely used in electrical, electronic, and mechanical fields that demand high reliability.
Advantages:
- Excellent High-Temperature Resistance: Class H insulation, it maintains high mechanical strength at elevated temperatures.
- High Mechanical Strength: The glass cloth substrate provides outstanding flexural and impact strength, making it suitable for structural components.
- Stable Electrical Properties: It retains excellent insulation properties and low dielectric loss even in high-humidity environments.
Technical Parameters:
| Attribute | Value |
| Density | 1.80~2.00 g/cm3 |
| Water absorption (3mm in thickness) | ≤ 22mg |
| Flexural strength perpendicular to laminations (normal) | ≥ 380MPa |
| Tolerances on thiness | 1±0.18mm / 2±0.28mm |
| Tensile strength | ≥ 300MPa |
| Dielectric dissipation (50Hz) | ≤ 0.04 |
| Relative Permittivity (50Hz) | ≤ 5.5 |
| Electric strength perpendicular to laminations (at 90℃±2℃ in oil), 1mm in thickness | ≥ 14.2 kV/mm |
| Insulation resistance (after 24 immersion in water) | ≥ 5.0 × 10^4 MΩ |
| Breakdown voltage parallel to laminations (at 90℃±2℃ in oil) | ≥ 35kV |
Applications:
- High-Voltage Electrical Equipment: Used for insulation plates and support components in high-voltage switchgear and transformers.
- Large Electric Motors: Serves as key components in generators and motors.
- Rail Transportation: Applied in insulation parts for locomotive traction motors and control systems.
