Conductor Metal and Materials

  • COPPER - The copper made use of in Part of RMJTCABLE items is defined in ASTM Specifications as UNS No. Copper energy covered as well as protected items could be produced in all 3 moods.
  • ALUMINUM - In many energy items, the light weight aluminum content is either readily pure light weight aluminum (Aluminum Association classification 1350) or light weight aluminum alloy - Aluminum Association classification 6201. In structure cable as well as wire items, the light weight aluminum web content is needed by National Electrical Code and also UL Standards to be an AA-8000 collection light weight aluminum alloy of electric conductor quality.


Stranding Constructions

  • CONCENTRIC - A main core cable bordered by several layers of helically used cords.
  • PRESSED - A concentric stuck conductor where each layer is gone through a closing pass away to minimize the size of the stuck conductor by 3%.
  • COMPACT - A concentric stuck conductor where each layer is gone through a closing pass away to decrease the size of the stuck conductor by about 10%.

Conductor Measurements

  • AMERICAN WIRE GAGE (AWG) - The conventional system utilized in the United States for assigning the dimension of electric conductors. AWG dimensions vary from No. 56 gage (0.00049 inch size) via 4/0 (0.460 inch size) for strong conductors.
  • ADVERTISEMENT MIL (cmil) - By interpretation, the location of a circle whose size is one mil (one one-thousandth of an inch). System is so tiny that the prefix "k" is generally made use of in signifying cable dimensions bigger compared to those covered by the American Wire Gage system. 250,000 round mils is generally signified 250 kcmil.
  • MIL - One one-thousandth of an inch (0.001 inch). Total sizes of cord as well as wire are typically revealed in mils. To transform to inches, just relocate the decimal factor 3 areas to the left or divide by 1000.
