Treeing deteriolation is one of the most common cause of polyethylene failure in service, As the quality of electric insulation extremely decline due to the inside and outside influence, into the effect of different factors, probably the growth trees is quite serious problem when polyethylene is established a place of strong radioactivity.
Throw on the polyethylene specimen with Co^60 r-ray of selective quantity and apply high voltage (AC60Hz) and examine into the growth of trees with variable time.
According to the results, it has been observed that as increasing X-Ray quantity the probability of the growth of trees is large and length of trees is long.
