in recent years, the development momentum of

electric industry in our country is rapid, forming a certain scale and perfect industrial chain, the production level of products has been greatly improved, and the quality of products has also been improved.

is in the stage of development at present. the demand for plastic case circuit breaker is huge and it is one of the important elements to promote industrial development. domestic enterprises need plastic case circuit breaker as an electrical component to improve the reliable operation of distribution system and provide control and protection for electrical equipment. the cost of

factory building in our country is relatively low. compared with the cost of foreign manufacturers,

has laid a good foundation for the development of domestic plastic case circuit breakers.

china's labor costs are much lower than foreign countries, so in recent years, many foreign enterprises put the production process in our country. in the construction of factories in southeastern coastal cities, the low price of labor is one of the main reasons.

, however, the gap between domestic and foreign manufacturers of plastic case circuit breakers is also obvious, mainly reflected in:

1. quality
          foreign manufacturers of plastic case circuit breakers attach great importance to quality management, with high quality as the production standard. plastic case circuit breakers produced by enterprises such as schneider, abb and siemens are of very reliable quality. domestic manufacturers often pay attention to the interests of materials and workmanship, so many products do not meet international standards.
          2. equipment
          many domestic plastic shell circuit breaker manufacturers'equipment are very old, and the working environment is relatively poor. under these factors, the product work level is low. it is difficult to achieve high detail processing, and the processing accuracy of internal parts is relatively low, which greatly shortens the service life of plastic case circuit breaker. moreover, the equipment has a low utilization rate of materials, and often wastes a lot of materials in the production process. and the plastic case circuit breaker manufacturers abroad, advanced equipment, product processing details in place, high utilization rate of materials. at present, the gap between our country and foreign manufacturers of plastic case circuit breakers is constantly seen, which combines the advantages of labor force with advanced science and technology. over time, plastic case circuit breakers manufactured by domestic manufacturers will compete with old brand products on the international platform.
