Kraft Paper Covered Insulated Wire – advanatges

1.Due to its high electrical, chemical and mechanical integrity, elasticity, flexibility, tear resistance, moisture and abrasion resistance, and excellent acid and alkali corrosion resistance, it will not be destroyed by insects, molds and fungi. It is compatible with all kinds of varnishes, adhesives, transformer fluids, lubricants, and refrigerants. Transformers using paper-covered wires can bring many economic, environmental and safety benefits to customers.

2.Reduce cost, reduce size, reduce weight. Using an insulated transformer, its temperature rise can be designed to 180°C, requiring less wires and iron cores, which can reduce the size and weight, thereby reducing infrastructure costs and facilitating installation. Smaller cores also mean less no-load loss;
