What are the fault terminals
As the surface of the insulator or the presence of metal residues, surface dust, flux and other pollution damp, organic material precipitates and harmful gas
the effective wall thickness of the insulator is getting thinner. This is the insulation material, injection mold precision and molding process put forward more stringent requirements.
So the insulation must have excellent electrical properties, mechanical properties and process performance. Especially with the high density, miniaturized terminal blocks are widely used
dsorption film and surface water film fusion to form ionic conductive channels, moisture absorption, mildew, insulating material aging and other reasons,
