1.The use of epoxy resin automatic pressure gel craft that APG technology manufacturing, product appearance, mechanical, electrical performance.

2.Selection of high-toughness resin production, excellent mechanical properties. And selection of low-formula system reactivity, slow curing, low-stress products to maximize the mechanical properties of products. 

3.Silica add activity to further improve the mechanical properties of epoxy resin, but also to ensure that the insulation work in the humid environment of long-term to maintain a good electrical insulation properties.

4.Add organic pigment, the product color bright, does not reduce the insulation performance.
