Product features
1. Excellent insulating properties:
DDP diamond lattice dispensing AMA forms a unique insulating structure by coating special modified epoxy resin on insulating paper in a diamond lattice shape. This structure makes the material excellent in electrical insulation, can effectively prevent current leakage and short-circuit phenomenon.
2. Good heat resistance:
The material has high heat resistance and is able to maintain a stable insulating effect in high temperature environments. This characteristic makes DDP diamond lattice dispensing AMA especially suitable for electrical equipment that needs to withstand high temperatures, such as oil-immersed power transformers.
3. Reliable adhesion:
In the process of use, the coating layer of DDP diamond lattice dispensing AMA 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 not only improves the stability of the insulation structure, but also enhances the durability of the electrical equipment.
4. Excellent mechanical strength:
DDP diamond lattice dispensing AMA has high mechanical strength and is able to withstand certain mechanical stresses and impacts. This characteristic makes it better able to withstand various stresses during the manufacturing process of electrical equipment, ensuring the stability and durability of the product.
5. Promote oil immersion and gas drainage:
As the resin coating of DDP diamond lattice dispensing AMA is in the form of dots, the coating produces only a trace amount of infiltration into the insulating paper during the melting and curing process. This characteristic helps the gas discharge and oil immersion in the insulating material, which reduces the occurrence of corona and local discharge phenomena and improves the reliability of the insulating structure.
6. Environmental friendliness:
DDP diamond lattice dispensing AMA meets the environmental protection requirements during production and use, does not contain harmful substances, and is harmless to the environment and human health.
Product introduction
DDP Lattice Dotting AMA is a kind of insulating material compounded by modified special epoxy insulating resin and electrical insulating paper. It forms a unique insulating structure by coating the special modified epoxy resin on the insulating paper in the form of a diamond grid. This structure makes DDP diamond lattice dotted AMA outstanding in electrical insulation, heat resistance and adhesion.
The material is widely used in the layer-to-layer and turn-to-turn insulation of oil-immersed power transformers. In the process of use, DDP Ringer Dispensing AMA can effectively prevent current leakage and short-circuit phenomenon, and improve the stability and durability of electrical equipment. At the same time, its excellent mechanical strength and adhesion also makes electrical equipment more safe and reliable when subjected to various stresses.
It should be noted that DDP diamond lattice dispensing AMA should be protected from moisture and avoid prolonged exposure to air during use, so as not to affect its insulating properties and adhesion. In addition, a dry and clean environment should be maintained during storage and transportation to ensure that the quality and performance of the product are not affected.

6641 F-CLASS DMD Insulating composite paper
As a Class F insulating material (long-term operating temperature of 155°C), 6641 DMD excels in high-temperature environments. Its core layer uses a high-melting-point polyester film (e.g., 6020 electrical insulation polyester film), combined with Class F adhesive, which remains intact (no delamination or blistering) for 10 minutes at 180±2°C. This heat resistance makes it suitable for high-load motors, dry-type transformers, and other equipment, maintaining stable performance even during short-term overloads (e.g., 200°C).
