Why Choose Derui Drop-out Fuses?

     Derui drop-out fuses are mainly applied in 10kV-35kV distribution network lines, high-voltage sides of distribution transformers, and cable branch points. Their core functions include short-circuit protection, overload protection and line section control, which are suitable for complex working conditions such as outdoor open-air sites, high-temperature and rainy areas.Standing out from the crowd with three core advantages, Derui drop-out fuses show remarkable superiority in terms of reliability, practicality and cost-effectiveness. The core highlights are as follows:

1. Upgraded Core Components with High Precision

•      fuse Tube Material:Adopting high-strength and high-temperature-resistant quartz sand material, it can withstand temperatures above 1200℃. Compared with ordinary ceramic tubes used by peers, its impact resistance and anti-cracking performance are improved by 40%, eliminating the risk of outdoor damage and electric leakage.

•      Fusing Precision:The internal fuse wire is made of silver alloy material, with a fusing precision error ≤ ±5%, far superior to the general level of ±10% among peers. It can quickly and accurately respond to faults, ensuring the safe and stable operation of power distribution equipment.

•      Craftsmanship and Service Life: Using professional silver plating technology, it features low contact resistance, anti-oxidation and anti-ablation properties. The measured service life is more than 15 years, far exceeding the average 10-year service life of peers. It reduces the later operation and maintenance costs, with reliability far ahead of industry counterparts.

2. Adaptable to Various Complex Scenarios

•      Protection Level:The outdoor protection level reaches IP65, better than most IP64 products of peers. It can effectively resist rainstorms and sandstorms, adapt to harsh outdoor environments in both northern and southern regions, and avoid the impact of internal water ingress and dust accumulation on operation.

•       High-altitude Adaptability: Optimized insulation structure improves insulation strength by 30% compared with peers, enabling adaptation to high-altitude areas above 4000 meters and solving the limitation that most peers can only adapt to areas below 2000 meters.

•      Flexible Installation:Supporting horizontal, vertical and inclined installation methods, it is suitable for different distribution network layouts without the need for additional customized accessories. The construction is convenient, avoiding the disadvantage of single installation method of peers.

•      Low-temperature Adaptability:It can fall flexibly without jamming in the severe cold environment of -40℃, suitable for cold scenes in northern regions, and avoids the expansion of faults caused by low-temperature jamming of products from other brands.

3. Convenient Operation & Maintenance with High Cost Performance

•       Efficient Operation and Maintenance: The visual fuse tube design allows operation and maintenance personnel to observe the fuse status and judge faults without disassembly, greatly improving efficiency, saving the trouble and risk of disassembly inspection, and enhancing operation and maintenance efficiency.

•      Outstanding Cost Performance: With the same performance, the price is 20%-30% lower than that of imported brands such as Schneider and ABB. Combined with its 15-year long service life and low failure rate, it has a significant advantage in long-term comprehensive use cost, which is more than 40% lower than that of similar imported products.

     With advantages in three dimensions including components, scenarios and operation & maintenance, Derui drop-out fuses are comprehensively superior to peers. They can meet the needs of various outdoor complex scenarios, reduce operation and maintenance as well as long-term use costs, and are suitable for scenarios with high requirements for product reliability and versatility, such as distribution network projects and rural power grids.
