Application Scenarios
Transformer Protection
Current-limiting fuses provide reliable protection for distribution transformers against internal faults and overload conditions, with thermal explosion indicators for quick fault identification.
Substation Equipment
Surge arresters with monitoring capabilities protect transformers, circuit breakers, and busbars in substations against lightning strikes and switching surges.
Distribution Networks
Dropout fuses offer economical protection for overhead distribution lines, providing visible disconnection and reliable fault clearance.
Industrial Plants
High-breaking capacity fuses protect capacitor banks, motor circuits, and other critical equipment in industrial environments.

FAQs About Fenarro's High Voltage Fuses & Surge Arresters
Q Do you provide monitoring systems for surge arresters?
AYes, we offer online monitoring systems that provide real-time status information and predictive maintenance alerts.
Q Can your fuses be used for transformer inrush current protection?
AYes, our transformer protection fuses are designed to withstand transformer inrush currents while providing fast protection against fault conditions.
Q How often should surge arresters be replaced?
ASurge arresters should be monitored regularly and replaced when the monitoring indicators show degradation, typically after 10-15 years or after major surge events.
Q What is the difference between current-limiting and expulsion fuses?
ACurrent-limiting fuses interrupt current before it reaches peak value, while expulsion fuses use gas generation to extinguish arcs. Current-limiting fuses provide better protection for transformers.
