Product Description

Product Description:

3240: A High-Performance Electrical Insulation Laminate

The Phenolic Epoxy Glass Fiber Laminate 3240 provides outstanding electrical and mechanical performance. This alkali-free reinforced laminate, with its Class B thermal stability, is the ideal choice for manufacturing critical insulation components and structural parts. It performs consistently even in challenging operating environments, including high humidity and immersion in transformer oil.

Advantages:

Excellent Dielectric Strength & Stability: Combines high perpendicular electric strength (≥14.2 kV/mm at 90°C in oil) with low relative permittivity (≤5.5 at 50Hz), ensuring reliable insulation against breakdown and minimal energy loss for enhanced operational efficiency.
Superior Mechanical Durability: Features a high-density (≥1.8 g/cm³), robust structure that provides exceptional long-term mechanical strength, making it ideal for demanding applications.
Impeccable Surface Quality: The smooth, defect-free surface facilitates easy installation and prevents performance issues such as partial discharges, guaranteeing consistent quality and long-term reliability.

Technical Parameters:

Attribute	Value
Color	Yellow
Shape	Board
Surface	Smooth/no Significant Defect
Density	≥1.8g/cm3
Water Absorption	≤0.5%
Tensile strength (MD)	≥200MPa
Compressive strength	≥350MPa
Vertical electric strength (at 90℃±2℃ in oil), 1mm in thickness	≥14.2kV/mm
Parallel breakdown voltage(at 90℃±2℃ in oil)	≥35kV
Relative permittivity(50Hz)	≤5.5
Insulation Resistance (Normal)	≥5.0×10^12 Ω
Temp. Index	120℃
Flammability	HB

Applications:

Ideal for Transformers: Relies on its exceptional dielectric strength (both parallel and perpendicular) for internal insulation.
Critical for Switchgear: Valued for its mechanical durability and impact resistance in high-strength environments.
Essential for Busbar Supports: Ensures stable power distribution thanks to its low and stable permittivity.
