HV Current Limiting Fuse

HV Current Limiting Fuse: Reliable Protection for High-Voltage Systems

When safeguarding critical high-voltage infrastructure, HV Current Limiting Fuses stand as the frontline defense against catastrophic failures. At Xi'an Green Power Technology, we engineer these fuses to deliver precision protection for power grids, renewable energy systems, and industrial applications. With a focus on ultra-fast fault interruption (≤5ms) and compliance with IEC 60282-1 standards, our solutions ensure your systems withstand extreme currents up to 20kA while minimizing downtime.

Product Overview

Our products are designed for indoor high-voltage distribution systems (3.6kV–40.5kV), offering robust protection for transformers, ring networks, and voltage regulators. Built to meet GB15166.2 and IEC282-1 standards, they combine rapid arc suppression with durable construction for harsh environments.

Key Specifications

Why Our HV Current Limiting Fuse Stands Out?

1. Ultra-Fast Fault Interruption

Engineered to react within milliseconds, our fuses limit fault currents before they escalate, protecting sensitive equipment in EV battery systems and grid substations.

2. Customizable Designs

Need a specific voltage rating or form factor? Our HV Current Limiting Fuse in-house R&D team tailors solutions for unique requirements, from 500V water-cooled variants to ATEX-certified models.

3. Renewable Energy Ready

Withstand temperature extremes (-50°C to +125°C) and UV exposure in solar/wind farms. Our DC-rated fuses (up to 1500VDC) reduce PV system downtime by 40%.

4. Automotive-Grade Durability

Vibration-resistant designs and hermetic sealing ensure reliability in rail traction systems and offshore wind installations.

5. Global Compliance

Pre-certified for UL, IECEx, and IRIS standards, our fuses integrate seamlessly into North American, European, and Asian markets.

Critical Applications

• Power Utilities: Protect 72.5kV+ substations from cascading grid failures.
• Solar/Wind Farms: DC arc suppression in combiner boxes and inverters.
