2.Advantage:

1.1/4 weight of metal box enables easy carriage and efficient work.

2.Corrosion-resistant and superior insulation.

3.Waterproof and dust-free product which gets through strict quality inspections.

4.Proved quality in many related tests(IP 66).

3. The influence of SMC to environment

It is proved that this project does not have obvious problem of environmental pollution, since the SMC encloses intactly, and few styrene gases are discharged. According to the national standard( TJ36-79), in workshop, the styrene density must be lower than 40mg/m3, and this project is totally. According with international stipulation. Waste gas may convulsions emission. It does not have the problem of sewage disposal since the water is no need in the production process. Besides, the production makes little noise. Therefore, SMC is the environment friendly material.

4. Electronic application:

SMC meter boxes,

Cable branch boxes,

Transforming and distribution boxes
