Company is a research and development, production, sales and service as one of the high-tech enterprises. Has been committed to for each family, manufacturing industry, service industry, party and government organs, the junior college. Research institutions. The use of products because of because of the humidity of the environment problem of mildew, qualitative change, oxidation and precision electronic components NPL ratio provide a full range of humidity solutions. The company produced the moistureproof box series industrial electronic ultra-low humidity moistureproof box, MSD anti electrostatic electronic moistureproof box, semiconductor electronic moistureproof box, electrical equipment damp. First, in the equipment insulation performance degradation, insulation aging acceleration. According to the theory of medium, environment humidity increases the dielectric conductivity, relative dielectric coefficient and dielectric loss angle tangent value increases, the breakdown field strength decreased. Worthy of note is that insulation failure process is often under the action of heat is brittle and cracking by vibration, moisture into the crack
