Applied Range
High Quality Materlals
High Purity Copper Material
The fuse element made of high purity copper metal material has the advantages of high electrical conductivity, good stability, low power consumption and low temperature rise.
The arc-extinguishing medium of the fuse is high-grade quartz silica. The advantage of this material is that it can extinguish the arc generated during the operation of the fuse, providing better heat resistance and higher arc discharge resistance.
High Grade Quartz Sand
High Performance Ceramics
The fuse body is made of high- performance ceramics, which has theadvantages of high temperature resistance, high insulation, high mechanical strength, and chemical inertness.

| Module | Chifeng fuse | Inferior fuse | Performance impact |
| Fusant material | High purity copper | Lead-tin alloy, common copper wire | Affect the fuse accuracy and reaction speed |
| Sheathing material | High-performance ceramics | Ordinary ceramics, recycled plastics | Affect insulation and arc extinguishing ability |
| Filler quality | High-grade quartz silica,Filling tightly | Ordinary quartz sand or substitute, loosely filled | Affect the arc extinguishing speed |
| Electrode material | Silver-plated copper electrode,low contact resistance | Ordinary metal, easy to oxidize | Affect temperature rise and energy consumption |
| Performance index | Chifeng fuse | Inferior fuse | Potential risk |
| Current-time characteristic | Precise and stable, matching the overload characteristics of the equipment | High dispersibility and instability | Mis-protection or insufficient protection |
| Breaking capacity | High breaking capacity, strong current limiting characteristics | Insufficient breaking capacity, poor current limiting effect | The fault escalates, resulting in system power outage |
| Arc control | Rapid arc extinction (microsecond level) | Slow arc extinction (millisecond level) | Cause a fire or explosion |
| Aging characteristics | Good long-term stability | Severe characteristic drift | Reliability decreases over time of use |
| Consistency | The differences between products are small | Different performance of products from the same batch | The protection effect is unpredictable |
