Insulation Parts
FUYI has over 25 years of experience in epoxy resin casting, producing customized insulation parts designed to meet strict quality, durability, and performance standards for bushings and epoxy terminals used in demanding high voltage environments.
- APG casting eliminates voids, ensuring PD below 10pC.
- High mechanical strength resists bending and impact reliably.
- Creepage distance customized for any pollution level.
CT/PT Transformers
Current transformers (CT) and voltage transformers (PT) are essential components in high-voltage power systems. They are designed to step down high currents and voltages to safe, measurable levels for metering, protection, and control devices.Power systems operate at high voltages and currents that cannot be directly measured or monitored by standard instruments. CTs and PTs provide accurate and isolated signal conversion, ensuring safety for personnel and equipment.
- Accuracy classes 0.2/0.5/5P for metering or protection.
- Custom ratios and secondary windings available on request.
- Partial discharge and withstand tests on every unit.
Surger Arresters
Our Lightning Arresters are specially engineered to provide reliable protection against both direct lightning strikes and various forms of electrical surges.In addition, our arresters integrate advanced surge protection capabilities that limit overvoltages caused by indirect lightning strikes, switching operations, or grid disturbances — functions typically associated with surge arresters.
- Metal oxide varistor core for low residual voltage.
- Composite housing offers explosion-proof, pollution-resistant design.
- Available for distribution, station, and capacitor applications.
Medium Voltage Fuse
Medium-voltage current-limiting fuses are critical protection devices designed to safeguard electrical equipment from overcurrents and short circuits. They operate by rapidly interrupting excessive currents, ensuring the safety and reliability of power systems.
- Reliable overcurrent protection for 6-35kV systems.
- Fast interrupting capability limits fault current damage.
- Sand-filled quartz construction ensures arc extinction safety.
- Compact design fits standard fuse holders easily.
