40.5kV Shielding Contact Box for ABB Switchgear is made from Epoxy Resin by APG technology, product appearance, mechanical, electrical performance.
1. Add shielding net to improve the product structure for reducing the partial discharge quantity.
2. Selection of high-toughness epoxy 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 resion, but also to ensure that the insulation work in the humid environment of long-term to maintain a good electrical insulationn properties.
4. Add organic pigment, the product color bright, does not reduce the insulation performance.
