ShareTHERMAL CONTRACTION AND CRACKING OF EXTRUDED POLYETHYLENE ELECTRICAL INSULATION AT CRYOGENIC TEMPERATURES.

Summary
THERMAL CONTRACTION AND CRACKING OF EXTRUDED POLYETHYLENE INSULATED MODEL CABLE WERE INVESTIGATED AT CRYOGENIC TEMPERATURES. IT WAS POSSIBLE TO COOL DOWN SAMPLES TO 77 OR 4.2 K WITHOUT CRACKING BY GRADUAL COOLING. RAPID COOLING OR LOCALIZED COOLING CAUSED LONGITUDINAL CRACKING. THE EXPERIMENTS AND THEORETICAL ANALYSIS SHOWED THAT GRADUAL GAS COOLING TO AT LEAST 135 K IS ESSENTIAL TO PREVENT CRACK FORMATION. EFFECTS OF CABLE BENDING AND MECHANICAL DEFECTS IN THE POLYETHYLENE INSULATION LAYER WERE EXAMINED.
