Product Details

Epoxy coated insulating paper

The base paper of our new product epoxy coated insulating paper is Tervakoski Tertrans N paper,and coat the special modified epoxy resin on the paper in net shape,then solidified to step B.It’s mainly used in high-low voltage coil and main channel insulation of oil immersed transformers.After winding and baking process,the epoxy coating insulating paper will increase the mechanical strength of the transformers’ coil.Improve the transformers’ ability to resist sudden short circuit.Therefore,the oil immersed transformers will work effectively and safely for long term.

Product Solidification Conditions
First curing under temperature 90℃±5℃ for 3 hours, and then rise temperature to 125℃±5℃ and keep 6 hours to cure;curing in accordance with the provision of both parties is also available.

Storage
Store in a dry,clean and well-ventilated warehouse, and keep away from fire and heat point, also keep away from the sun. The storage period is one year, qualified products exceeding the storage period can still be used.
