Dielectric breakdown occurs when electrical stresses converge overa small area. Stress control tubes are used to distribute electricalstresses at the end of the semi-conducting cable screen, to preventdielectric break down. The tubes have high permittivity and aresuitable for applications up to 36kV. Colour of the tubes is blackand the maximum delivery length is 1000mm RANGE & DIMENSIONSNO.SIZESI.D As supplied(mm)I.DAfter recovery(mm)Wall ThicknessAfter recovery(mm)1ST 30/1230122.102ST 35/1535152.403ST 40/1840182.504ST 50/2050202.505ST 60/2560252.506ST 75/3075302.507ST 95/4295423.00SPECIFICATIONSNO.PropertyTest MethodTypical value1Tensile StrengthASTM D-41212 N/mm22Ultimate ElongationASTM D-412300%3Heat Shock@ 250º C / 30 minASTM D-2671No Cracking / No Flow4Low Temp.
