In Okken, Rusty cutting edges of cable tie support 87176 & 87177 are visible to customer, How to avoid this problem and what is the solution?
The problem:
The cable tie supports 87176 & 87177 are usually made of pre-plated Galvanized Iron sheets (FTR00052 - DX51D+Z275-M-B-C), In some environmental conditions the cutting egdes become quickly rusty and visible. The paint touch up on these edges is not recommended.
Solution:
We have recommended to use the Steel sheet DC01, finish the fabrication process and then go for plating Fe/Zn8/C1. Which is mentioned in the attachment - HRB7180100
Hereby we do not recommend to go for paint touch up on the rusty edges or full painting of these parts due to the following reasons,
The painting or power coating will make these parts non-conductive.  Inside the swichboard we have to maintain the continuty between different sections for earthing purpose. (Non earthing will lead to performance issues)
In Okken, these parts are not only to fix the cables but also to fix the protective earthing (PE) busbars which is subjected to continuity and short circuit withstand.
