How to protect the neutral coil in a distribution box
The neutral wire in plastic weatherproof electrical box should be connected through the terminal board and separated from the terminal board to protect the neutral wire. To effectively address this issue, the following measures can be taken: 1、 Inspection and Cleaning Power outage inspection: Firstly, ensure that the power supply has been completely cut off to. When delta-wye power transformers are installed in a distribution substation, the neutral is usually solidly grounded and needs no surge protection. Narrow down the scope of influence of the fault, and act to disconnect the circuit. The rules for the disconnection or maintaining of the neutral conductor are designed to limit the risks of electrocution, which accompany an increase in potential. There should be no exposed live parts in waterproof cable box. of the neutral conductor is lower than the phase c.

Should we coil the fiber first or melt it first
The rule is to coil the fiber once after each splicing and heat shrinking of one or several optical fibers in fiber optic sleeve or optical fibers in a branch direction optical cable. During the fusion process, the “V” groove, electrode, objective lens, and fusion room. Therefore, it is necessary to avoid bird's-nest fiber coiling; to coil fiber well is a meticulous job that requires great patience and does not allow for any sloppiness. Before fiber coiling, the optical cable and pigtail should be pre-processed, and the optical cable and pigtail should be opened. A fusion splicer is a specialized tool used in fiber optic networks to join two fiber optic cables together permanently. It works by applying heat to the ends of the cables, causing them to melt and fuse together. Result is a near-seamless / lossless joint. The article below offers more detail on fusion-splicing procedures, especially the fiber “prep.
