What happens when long length of cables are bundled together?
The Latest Bundling Issue
And the larger the bundle, and the smaller the gauge, the more the cables will heat up . When a cable's temperature rises, so does insertion loss—the loss of signal power that can prevent proper data transmission.
What happened when long length of cables are bundled together?
If you have many cables in a bundle all conducting the full rated current bundled together the air cannot surround the cables in the center to naturally dissipate the heat. This means the center cables will overheat causing the insulation to over heat and deteriorate .
Is it OK to tape wires together?
Electrical tape is good for insulating wire. It cannot hold wires together . In this case, the solder is holding the wires, but I really wouldn't trust solder for electrical wires. Wires can get warmer when in use, which could weaken or break the solder.
