Our FR4 epoxy sheet order was signed with a Laos customer today, which used for the transformer insulation.

Our FR4 epoxy sheet order was signed with a Laos customer today. Customers apply to transformer insulation boards. The customer chose an insulation board of 1020mm * 1220mm. This product is a plate-shaped insulating material made of glass fiber cloth impregnated with epoxy resin as an adhesive and dried and hot-pressed. It has high mechanical properties, water absorption, flame retardancy and heat resistance, and the dielectric properties are stable after immersion in water. Customers have been struggling with which epoxy board to choose, is it G10, G11 or FR4? Our business manager recommended FR4 to the customer after determining where it was used. Why is FR4 more suitable?
