Key Application Areas
1. Power Transformers
Electrical insulation materials are essential components in power and distribution transformers. They provide:
Electrical isolation between windings
Mechanical support under short-circuit forces
Thermal stability under long-term operation
Common applications include insulation cylinders, spacers, end rings, clamping structures, and structural components.
Materials such as GPO-3, UPGM series laminates, phenolic laminates, and epoxy-based composites are widely used.
2. Switchgear and Power Distribution Equipment
In medium- and low-voltage switchgear, insulation materials ensure:
Safe phase-to-phase and phase-to-ground separation
Flame resistance and arc fault protection
Structural stability and dimensional accuracy
These materials are extensively used in busbar supports, panel insulation plates, arc barriers, and mounting components, especially in compact and high-load systems.
3. Motors and Generators
In motors and generators, insulating materials must withstand:
Electrical stress
Heat generated during operation
Mechanical vibration
Applications include slot wedges, insulation boards, structural supports, and terminal components, where high mechanical strength and thermal resistance are critical.
4. Railway and Rail Transit Equipment
Railway and urban transit systems require insulation materials that meet strict fire safety standards. Insulation components are used in:
Traction transformers
Converters and inverters
Control cabinets and power modules
Compliance with standards such as EN 45545 is increasingly essential in this field.
5. Industrial Electrical Equipment
Electrical insulation materials are also widely applied in:
Industrial control cabinets
Energy storage systems
Renewable energy equipment (wind and solar inverters)
High-end electronic and automation systems
These applications demand materials with consistent quality, long service life, and environmental compliance.
