Waterproofing of Outdoor Jumper Cable
19
• Spiral-wrap one layer of insulating adhesive tape: After the feeder is connected, spiral-wrap one-layer insulating adhesive tape around the connector with 50% overlapping, ensuring that an excess of 10 mm insulating adhesive tape is reserved at the tail of the connector. Remember that you must apply proper force while spiral-wrapping the insulating tape.
• Spiral-wrap three layers of waterproof adhesive tape: Stretch the waterproof adhesive tape two times as long as its original length. Use approximately 50 cm waterproof adhesive tape for each connector. Spiral-wrap three-layer waterproof adhesive tape around the connector in the direction that you tighten the feeder. This can protect the feeder from being loosened during the spiral-wrapping process. Smooth over the waterproof adhesive tape by applying proper force to secure it on the feeder.
