There is a large demand for cable accessories in the future power market

The cable and accessories industry will continue to be in development for the next fifteen years. The annual installed capacity of new power generation will exceed 100 million kilowatts, and the newly added power will be delivered to users. The power transmission transformers will be four times the installed capacity. To connect these devices, wire and cable accessories are required. .

It is predicted that by 2020, China's power generation capacity will reach 1.47 billion kilowatts. Even so, the average per capita is only 1 kilowatt. Compared with the average of nearly 3 kilowatts in the United States, there is still a big gap. With such a large installed capacity, more power transmission and transformation equipment is required, and the cable required to connect these power transmission and transformation equipment will naturally be very large. It is estimated that for every additional kilowatt of power generation capacity, a 100-meter cable will be required.

Attachment is required for so many cables, ie cable terminations. Only when the connector is installed with it can it be connected to other electrical equipment. According to the main insulation molding process, commonly used cable terminals and intermediate connectors of 35KV and below can be mainly divided into packaged cable accessories, heat-shrinkable cable accessories, prefabricated cable accessories, cold-shrinkable cable accessories, and plug-in terminals. At present, the use of wrapped and heat-shrinkable and prefabricated cable accessories is declining, and the use of cold-shrinkable cable accessories and plug-in cable accessories is on the rise.

It is not difficult to see from the above cable accessories product classification that the cold shrinking technology that simplifies the on-site installation requirements has occupied an important position in the development of cables, and the recent proposal by the state to replace the heat-shrinkable cable accessories with cold-shrinkable cable accessories. The main force of the future cable accessories must be the cold-shrink cable accessories.
