How to distinguish the quality of steel wire in optical cable
Good fiber optic cable will generally use high modulus phosphating steel wire, short-term tension is 1500N or 3000N. The inferior fiber optic cable will be replaced by iron wire or ordinary steel wire with a small diameter, which is easy to rust on the one hand;

How to distinguish the quality of steel strip and aluminum strip in optical cable
The steel strip and aluminum strip in the optical cable are mainly used to protect the optical fiber from mechanical side pressure, moisture-proof and other effects. The better optical cable generally uses chrome-plated steel strip. Low-quality optical cables replace chrome-plated steel strips with ordinary iron sheets or black sheets (uncoated steel strips) with only one side of anti-rust treatment. Over time, corrosion will occur in the optical cables and hydrogen loss of the optical fibers will increase. Moreover, due to their easy separation from the sheath, they cannot form a comprehensive adhesive sheath and their moisture-retaining performance is very poor. Some use tinned steel strips instead of chrome-plated steel strips, tinned steel strip surface, bubbles, etc. are inevitable.

Process steps for anti-corrosion of power fittings
The hardware used in the power system needs to bear a large tension in order to ensure the normal connection of the line, so the damage of the hardware may cause line failure. 10KV and above high-voltage distribution lines in addition to a small number of cables laid underground, most of the cables are set up in the open air. The cross arm of the iron tower belongs to the above-mentioned power fittings and is used to support the weight of the cable in the line. However, there is only a bottle (or overhang) distance between the high-voltage cable and the earth, and the insulation distance is short. Once the cross arm of the iron tower is exposed in the air and corroded, the safety, stability and continuous operation of the line will be affected. Especially in the industrial developed areas with high acid content in the air, due to acid corrosion, the aging speed of the cross arm of the iron tower will be accelerated, which is easy to produce corona phenomenon and trip accident.
