Since the advent of the vacuum switch tube, the product has been developing towards miniaturization, long life, low cost, high current, etc. With the continuous expansion of the application scope of this product, its development direction has become more and more clear.

The future development direction of vacuum switch tube is as follows:

1. Miniaturization. With the optimization of the internal electric field, the volume of the product can be made smaller and smaller, especially the use of composite insulation technology, which also reduces the structure of the product. At present, the research and development of the miniaturization of this product has achieved certain results in the industry. Some companies have developed products that can be reduced to half their original size.

2. Low cost. The miniaturization of this product can undoubtedly save a lot of raw material costs for enterprises. The cost is reduced, and the price of natural products will also be reduced. In addition, the greatly improved process level also leads to improved production efficiency and further reduced production costs.

3. High current. The rated working current of some places of use is relatively large, so it is required that the product needs to have a higher recovery speed after the short-circuit current is interrupted. Therefore, there will be certain restrictions on the use in this area. In recent years, with the progress of research and development technology , many manufacturers can produce high-current products.

4. Long life. Since the product needs to be disconnected and connected frequently, its service life should not be too short. With the emergence of new operating mechanisms, the improvement of bellows technology, and the realization of assembly process optimization, long-life products are also coming out. For a product to have a long lifespan, it still takes time to develop.

In today's market division of labor is constantly subdivided, the vacuum switch tube is also developing in the direction of specialization, and many special products have emerged as the times require.
