Abstract :
The hot-ageing of electrical insulating paper made of oxygen-alkali (O-A) kenaf bast fibre was investigated. After hot kinetic stress, the mechanical strength of the kenaf bast fibre decreases somewhat, but the electrical properties do not change throughout the whole process. Either in air or in a transformer, the kenaf bast fibre electric insulating paper and press board´s deterioration rate of the hot-ageing property is similar to that of NUKP electric insulating paper and press board. Because the initial value of this property is greater for the kenaf bast fibre pulp, its absolute value after ageing is also greater
