Lightning accounts for about 60% of all transmission line trippings in China and is closely linked to season as well as region. Based on the physical processes, lightning overvoltages can fall into two broad categories: those caused by direct strike to the tower, shield wire or conductor; and those where lightning strikes the ground near lines, generating an induced overvoltage on conductors.

Composite insulators have become the dominant type selected for use on overhead lines and have also been growing rapidly in application at substations.

Increased penetration of Distributed Generation (DG) from solar and wind plants has created challenges for network operators when it comes to power quality issues such as voltage regulation, power factor and harmonics.

Heat-shrinkable accessories are mainly based on the characteristics of the cable structure, which can not only restore the performance of the cable but also ensure the extension of the cable length and the connection of the terminal. The reliability of high-pressure heat shrinkable accessories can be judged from the aspects of electrical performance, sealing and moisture-proof performance, mechanical performance, and process performance. So what are the common profiles of heat shrinkable accessories? Let's take a look next.

Porcelain and glass string insulators have been widely used in suspension applications on UHV DC projects in China due to their mechanical and electrical properties and also the depth of local operating experience.

The separable connector generally refers to the electrical connector. That is a device that connects two active devices to transmit a current or signal. So what are the benefits and product categories of separable connectors? Next, let's go take a look.
