MOLDED PARTS Qualtek Electronic s QMB HEAT SHRINKABLE MEDIUM VOLTAGE BREAKOUT UP TO 36kV Features/Application s Medium voltage breakouts are made from radiation cross-linked polyolefin. This specially designed material performs exceptionally as an electrical insulator. The material will not crack and is UV resistant, weather proof and flame retardant. These breakouts can be safely used in protecting cable ends up to 36kV from flashover or surges created while working with switchgear and transformer boxes.
