ZTELEC Insulation Materials | 18-06-29

Many people find that if you search for DDP directly on Google Chrome, two search results will appear.
The first is the insulating material DDP.
Insulation DDP is an abbreviation of Diamond Dotted Paper.
DDP is a kind of insulating material made of special modified epoxy resin on electric insulating paper.
ZTELEC DDP is widely used for interlayer insulation and inter-turn insulation of oil-immersed power transformers. When used, the coating begins to melt at a certain temperature during the process of coil drying, producing adhesion, and curing as the temperature increases. This allows the adjacent layers of the winding to be reliably bonded into one fixed unit. The adhesive strength of the epoxy resin is sufficient to prevent the displacement of the layers of the winding in the event of a short circuit, thus ensuring the long-term electrical and mechanical properties of the insulating structure.
The resin coating of DDP is in the shape of a dot, which ensures the immersion of the oil and the discharge of gas in the insulating material, effectively avoids corona and partial discharge, thereby ensuring the safety and reliability of the insulating structure.
