Diamond Dotted Paper

Diamond dotted paper is one of insulating materials, which is made of electrical Kraft paper coated on one side or both sides with modified special epoxy resin in diamond-shaped form. It has higher electrical strength and mechanical property

Product Application

Diamond Dotted Paper is a high-performance insulating material, mainly used for turn insulation and interlayer insulation of oil-immersed power transformer coil conductors.
Diamond Dotted Paper’s conventional thickness is 80um 130um 180um 200um 250um 300um Width: 625mm 980mm

Product Features

1. Unique diamond-shaped coating:
Diamond Dotted Paper forms a unique insulation structure by coating special modified epoxy resin in a diamond-shaped pattern on high-performance insulating paper. This structure not only improves the insulation performance, but also promotes the infiltration of oil and the discharge of gas in the insulating material, effectively avoiding the occurrence of corona and partial discharge.

2. Excellent insulation performance:
The special modified epoxy resin has good insulation performance, which can ensure that Diamond Dotted Paper maintains a stable insulation effect under high voltage environment and prevents the occurrence of current leakage and short circuit.

3. Reliable adhesion:
During use, the coating layer of Diamond Dotted Paper will begin to melt at a certain temperature and produce adhesion. As the temperature rises, the coating layer will begin to solidify again, so that the adjacent layers of the winding are reliably bonded into a fixed unit. This adhesion ensures the stability and durability of the insulation structure.

4. Good heat resistance:
Diamond Dotted Paper can maintain stable performance in high temperature environment and is not easy to age and fail. This characteristic makes it particularly suitable for electrical equipment that needs to withstand high temperatures, such as oil-immersed power transformers.
5. Environmental protection:
Diamond Dotted Paper meets environmental protection requirements during production and use, does not contain harmful substances, and is harmless to the environment and human health.
