Waterproofing Outdoor Cables
The waterproof tape should be wrapped for an extra length of 20
mm [0.8 in.] away from the connectors at both ends.
The tapes should be wrapped around the connector from the
lower part to the upper part. When wrapped for another layer, the
tapes may not be cut.
When wrapping the waterproof tape, apply even force to extend
the tape until the width of the tape is 1/2 of the original width.
When wrapping the waterproof tape, ensure that the upper layer
of the tape covers at least 50% of the lower layer.
The insulating tape should be wrapped for an extra length of 20
mm [0.8 in.] away from the connectors at both ends.
The last layer of the waterproof tape should be wrapped from
the lower part to the upper part to prevent rainwater from
infiltrating into the tape.
1. Wrap three layers of waterproof tape.
2. Wrap three layers of insulating tape.
