MEDIUM VOLTAGERIGHT ANGLE / STRAIGHT BOOT
UP TO 36kV
Features/Applications
The medium voltage right angle boots and straight boots are made from
radiation cross-linked polyolefin. With the specially designed formulation,
the boots are excellent electrical insulators and have great anti-tracking,
UV resistant, weather proof and flame retardant properties. It can be safely
used in protecting cable ends up to 36kV against flashover or surges
induced while working in switchgear and transformer boxes.
Operating temperature: -55°C to +100°C
Minimum shrink temperature: 110°C
Minimum full recovery temperature: 130°C
RoHS Compliant
