UL Single Core Wire long-term overload operation overload operation, because of the thermal effect of the current, the load current through the cable must cause the conductor heating, at the same time, the skin effect of charge and the eddy current loss of steel armor, insulation medium loss will also produce additional heat, so that the temperature of the cable increases. Long-term overload operation, excessive temperature will speed up the aging of insulation, so that insulation breakdown. Especially in the hot summer, the temperature rise of the cable often leads to the first breakdown of the thin insulation of the cable, so in the summer, the fault of the cable is particularly many. There are many common ul electronic wires, and the first is to rely on insulation and sheath information to distinguish. According to the different insulation and sheath data, it is mainly divided into PVC electronic wire/low smoke halogen free electronic wire/silicone wire/Teflon electronic wire and so on. The cost of ul electronic wire mainly includes the cost of copper and rubber cost, so the cost of electronic wire = copper cost + rubber cost.
UL Single Core Wire flexible mineral insulated cable is the collection of plastic cable functional advantages, "fire" is only one of its intuitive performance of the function. Non-combustible, flexible, explosion-proof, anti-corrosion, waterproof, anti-magnetic, anti-mechanical damage (including animal biting), high load, strong overload capacity, etc., the effect of any function is far better than that of plastic cable. And has a very good riot resistance, can prevent the steam flame in the cable connecting parts through. And its diameter is smaller than other rated current opposite cable, and waterproof effect, special consolidation and durability, can be destroyed through fierce machine, and will not damage other electrical function.
