Question Pros / Cons of Umbilical for Trident

[Mr_Saint]

Silicone is meant for high temperature but has high friction. The high friction limits movement in the wire bundle, increasing stress on the inner and outer wires, making the bundle act like a big fat wire. And silicone is also very flexibile which actually hurts because the flexibility means that the stresses are carried more by the copper. PTFE wire is less flexible, and generally has thicker sheathing which acts as a better strain relief, but has lower friction as well.

In my experience, PTFE sheathing is thinner than silicone, allowing you to stuff more of them in the same cable chain.

You are correct. I have FEP wires for my CANBUS setup and they are thinner than silicone given the same wire gauge, while PTFE is even thinner yet.

22 gauge outside wire diameter via McMaster-Carr:

Silicone .12"
FEP .07"
PTFE .05"

I may need to run some sort of stiffener through the cable sleeve to keep it from kinking at the top of the cable gland. It's not as bad as it appears in the pic, but I don't like it.

where can i find this stuff for the wires?
also the stls?

There was a post a couple days ago on Discord with a bunch of links. I just copied and saved them, haven't explored any yet.

The easy version is to run a piece of filament through the umbilical. that typically stiffens things up pretty well.

Where did u source ur parts for the un iCal. Am planning this mod.

You mean imbilical?
You need 4 wires, some PE sleeving, and PG7 cable glands. Or CNlinko instead as connector.
If you need printed parts, those depend on what CAN board you plan to use.
