FR4 insulation board for switchgear components

FR4 insulation board, a crucial material in the electrical equipment field, plays a key role in the insulation of switchgear components. This board, composed of epoxy resin and glass fiber composites, has become a preferred solution in industrial insulation due to its stable dielectric properties and mechanical strength. XUJUE ELECTRICAL‘s FR4 insulation boards utilize mature processes to effectively meet the customized needs of switchgear of various specifications. They can also process FR4 insulation material according to customer-provided drawings to create customized parts.

In high-voltage switchgear manufacturing, FR4 insulation boards are mainly used in core components such as circuit breaker supports and busbar isolation plates. Its high heat distortion temperature characteristics can withstand the instantaneous temperature rise during equipment operation, and precise thickness tolerance control ensures the tightness of component assembly. Compared with traditional insulation materials, the flame retardant rating of FR4 insulation boards better meets the safety standards of modern power equipment.

XUJUE ELECTRICAL optimizes the fiber weave structure of FR4 insulation boards, giving the finished product more balanced mechanical properties. This characteristic is particularly suitable for switchgear connection components that need to withstand mechanical stress for extended periods, significantly reducing the risk of insulation failure due to vibration. The availability of multiple specifications allows purchasers to flexibly select the appropriate model based on specific operating conditions, avoiding material waste.

Key Advantages of FR4 for Circuit Breaker Supports

Stable volume resistivity ensures safe equipment operation.
Low water absorption design is suitable for use in humid environments.
Environmentally friendly resin formulation meets environmental standards.
UL certified and compliant with IEC standards.

Procurement Advice

When purchasing FR4 insulation boards, it is recommended to focus on interlayer adhesion strength and flatness. XUJUE ELECTRICAL provides professional factory testing reports and third-party testing reports for each FR4 epoxy board to help users verify material parameters. For the processing requirements of irregularly shaped components, pre-impregnated FR4 insulation board blanks can be used to reduce subsequent processing steps.

With the advancement of smart grid construction, the application of FR4 insulation boards in new switchgear continues to expand. XUJUE ELECTRICAL has further improved the arc resistance of the boards by refining the epoxy resin curing process, providing equipment manufacturers with a more reliable basic material guarantee.
