BK/SC-20

Fuses are an indispensable part of an electrical grids\' safety system, and BK/SC-20 is one of the most widely-used medium-voltage fuses available in the market. Although the BK/SC-20 applications may vary, they are typically used to protect transformers, high-tension lines, and distribution systems in both residential and commercial settings.

The BK/SC-20 fuse is a current-limiting device specifically designed for medium-voltage power transmission lines. Its working principle is based on the melting of the internal fuse element, which is calculated to actuate at the characteristics current. When the current through the element reaches the designed level, the element melts and then breaks the circuit, thus protecting it. This type of fuse has a short-circuit current-limiting feature, which is important when dealing with medium-voltage power transmission lines, as it limits the amount of energy released into the system when it trips.

The BK/SC-20 fuses are available in two different types: indoor and outdoor. Both types are designed to protect against over-currents, providing reliable protection for the entire system. The indoor version features a terminal cover which provides additional protection from the environment, while the outdoor version is designed to withstand harsher environmental conditions.

One of the advantages of the BK/SC-20 fuses over other types of fused devices is their low cost. Unlike some other types of fuses, these don\'t require special welding processes and are easily installed in the system. The enclosure has an IP rating that indicates its resistance to water and dust, which is important for outdoor applications, where the elements are exposed to weather elements such as rain and wind.

The BK/SC-20 also has a number of safety features that make it attractive in the market. This includes an anti-arcing device, which helps to reduce the possibility of sparking when the fuse is activated. It also has a corrosion-resistant brass pin, which helps to improve the longevity of the device. In addition, this type of fuse is designed with a self-extinguishing mechanism, so that when the fuse is triggered and the electricity is cut off, the fire risk is minimized.

The BK/SC-20 fuse is an ideal choice for many types of medium-voltage applications. It is easy to install, cost-effective, and highly reliable. It has a wide range of safety features and is designed to withstand harsh weather conditions. As a result, it is often chosen as the preferred type of fuse in many medium-voltage power transmission lines.
