PT Journal AU Cech, R Burval, L Klaus, P TI Measuring the Electric Strength of Board Composite Materials and Insulators SO Transactions on Transport Sciences PY 2011 BP 19 EP 24 VL 4 IS 1 DI 10.2478/V10158-011-0003-y DE Electric strength; composite; insulators. AB This article contains the results of electric strength measuring of board composite materials and electrical insulators. It describes and briefly specifies the measured materials, i.e., the composites based on Glass, Kevlar and Carbon fiber. The composite electrical insulators are Kartit, Glasstextite and Textite. The measurement description shows the measurement system diagram and parameters of the used testing high-voltage source. The evaluation suggests the possibility of using composite materials as electromobiles' construction components which require specific electrical properties. ER
