1. The features of the high quality fuse cut out 10kv polymer or drop out fuse cutout

The function of a fuse is to protect current. A fuse is composed of a melt and a melt tube, which are connected in series as metal conductors in a circuit. When the current exceeds a certain value, the fuse will generate heat to melt the melt, thereby disconnecting the current and achieving protective effects. Fuses are widely used in various electrical and electrical equipment due to their simple structure and convenient use.

Fuse cut out refers to a protective device that uses the heat generated by itself to fuse the melt and disconnect the circuit when the current exceeds the specified value. It mainly consists of three parts: the melt, the shell, and the support, among which the melt is a key component for controlling the fusing characteristics. The material, size, and shape of the melt determine the fusing characteristics. Melt materials are divided into two categories: low melting point and high melting point. Low melting point materials such as lead and lead alloys have a low melting point and are prone to melting. Due to their high electrical resistivity, the cross-sectional size of the melt produced is larger, and the metal vapor generated during melting is more. They are only suitable for fuses with low breaking capacity.

High melting point materials such as copper and silver have a high melting point and are not easy to fuse. However, due to their low electrical resistivity, they can be made into smaller cross-sectional sizes than low melting point melts. They produce less metal vapor during melting and are suitable for fuses with high breaking capacity. The shape of the melt can be divided into two types: filamentous and banded. Changing the shape of the variable cross-section can significantly change the fusing characteristics of the fuse. Fuses have various different fusing characteristic curves, which can be suitable for the needs of different types of protection objects
