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, finishing the fabrication process, and then going 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 powder coating will make these parts non-conductive.  Inside the switchboard board we have to maintain the continuity 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 are subjected to continuity and short circuit withstand.
