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.

The basic performance of plug accessories can be divided into three categories: mechanical performance, electrical performance, and environmental performance. Another important mechanical performance of plug accessories is the mechanical life of plug-type accessories. The mechanical life of plug accessories is a durability index, which is called mechanical operation by national standards. Plug-type accessories use one plug-in one-unplug cycle, and the judgment is based on whether the plug-type accessories can normally complete their connection function after the specified plug-in cycle. Next, let's take a look at the basic performance of plug-type accessories.

Post insulators are generally used as insulators for overhead power lines in villages and towns, and can play an important role in overhead transmission lines. Composite post insulators can effectively use narrow corridors for open-voltage power transmission, are suitable for urban network technical transformation, can reduce the height of poles and towers, and can save a lot of manpower, material and financial resources. Composite post insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to the ground. These two functions must be ensured. Composite post insulators should not be caused by changes in the environment and electrical load conditions. Otherwise, the composite post insulator will not have a significant effect and will damage the use and operating life of the entire line.
