In the case of laying power cables along marshes or water, the whole power cable capable of withstanding tensile force should be selected. When passing through a small stream, a power cable with armor (used outside the armor) should be used.
General household wires have an expiration risk of being used under normal conditions for more than 10 years. Our common household wire is pvc housing wire, 2.5mm2 wire, 4mm2 wire, 6mm2 wire, and aluminum xlpe concentric cable.
The copper core yellow is reddish, indicating that the copper used is of good quality, while the yellowish white is the reaction of low quality copper.
The complete naming of wires and cables is often complicated, so people sometimes use a simple name (usually a category name) in combination with the model specification instead of the full name, such as "low voltage cable" for all plastic insulated power of 0.6/1kV class.

Copper core and AAC conductor cost comparisonThe AAC Conductor chemical composition, it is easy to see, the above AAC Conductor elements accounted for 90 percent, is the main component of the AAC Conductor, a relatively small proportion of other trace elements, little difference in the cost of computing Since at present there are no standards regardin...
AAC conductor safety is better than copper coreUnlike traditional copper cable, AAAC conductors with high elongation aluminum alloy, in aluminum by adding iron and other materials, and pressed through a special process and stranded annealed alloy aluminum voids "squeeze pressure "clean, reducing the cross-sectional area and having good fl...
