HEAT SHRINKABLE MEDIUM VOLTAGE BREAKOUT
UP TO 36kV
Features/Applications
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.
Operating temperature: -55°C to +105°C
Minimum shrink temperature: 110°C
Full Recovery Temperature: 120°C
Standard color: Red
RoHS Compliant
