The 400 kV Gutinas-Brasov overhead line is located in a mountainous area of Romania that has mostly rocky soil. Thick ice covers conductors during winter and in the past caused breakage of shield wire such that it had to be dismantled in the most severely affected sections.

South Bohemia abounds with wonders, including medieval towns with cobblestone streets and fairy tale castles. But what is truly unique in this pastoral region of the Czech Republic has nothing to do with baroque villages.

Transmission lines often must traverse mountain ranges or plateaus situated at least 1000 m above sea level. In such cases, design of transmission and distribution systems has to take into account fundamental changes in insulation performance associated with high altitude.

Lightning Arrester is an electrical appliance used to protect electrical equipment from high transient over-voltage hazards during lightning strikes, limit the freewheeling time, and often limit the freewheeling amplitude. A lightning Arrester is sometimes called an overvoltage protector or overvoltage limiter. Next, let's take a look at the introduction of Lightning Arrester. Here are some answers.

The current-limiting fuse is a closed fuse that can limit short-circuit current and can quickly cut off the fault current. Its structure is characterized by placing the melt in a closed porcelain tube filled with quartz sand. There are also additional current-limiting resistors in series to limit the short-circuit current and reduce the overvoltage caused when the current is cut off. So, let us take a look at the introduction of the current-limiting fuse. Here are some answers.

Cable Accessories are products that connect cables with transmission and distribution lines and related power distribution devices. The reliability of high-voltage Cable Accessories can be judged from the aspects of electrical performance, sealing and moisture-proof performance, mechanical performance, and process performance. So, let us take a look at the introduction of Cable Accessories. Here are some answers.
