2. Principle of increasing breakdown voltage

Breakdown voltage refers to the critical voltage in which the insulating material loses its insulating properties under the action of an electric field. Increasing the breakdown voltage of the insulating layer means enhancing the equipment’s ability to withstand high voltages, which is crucial for the safe operation of high-voltage power equipment.

Mechanism of action

Tri(dimethylaminopropyl)amine increases the breakdown voltage of the insulating layer in the following ways:

Enhanced intermolecular forces: By forming hydrogen bonds or other types of chemical bonds with polymer chains in insulating materials, it increases cohesion between molecules and reduces molecular movement under the electric field.
Improve surface characteristics: Change the charge distribution on the surface of the insulating layer, reduce the local electric field strength, and prevent breakdown caused by the concentration of the electric field.
Inhibition of the growth of electric branches: Electric branches are conductive channels formed inside the insulating material under high voltage, and tris(dimethylaminopropyl)amine can effectively inhibit the formation and development of these channels.

Experimental data support

According to many domestic and foreign studies, after adding an appropriate amount of tris(dimethylaminopropyl)amine, the breakdown voltage of the insulating layer can be significantly increased. For example, some experimental data show that under standard conditions, the breakdown voltage of the polyethylene insulating layer without tri(dimethylaminopropyl)amine is 20 kV/mm, and can be increased to above 25 kV/mm after addition.

Material Type	Raw breakdown voltage (kV/mm)	Breakdown voltage after addition (kV/mm)
Polyethylene	20	25
Silicone Rubber	18	22
Polypropylene	16	20
