Welding cable cadivi made in Vietnam This is a new product recently produced by Cadivi and put into the consumer market, manufactured according to domestic standards.
To choose a conductor you need to know the load current to use, along with allowable current density for each type of conductor.
We can apply the following formula to approximate calculation:
– S: is the conductor cross-section, in mm2
– I: is the current flowing through the square cross-section, in Ampere (A)
– J: is the allowable current density (A/mm2)
Permissible current density of copper wire J~ 6A/mm2
Allowable current density of aluminum wire J~ 4.5 A/mm2
In case of branch line in 220VAC voltage family (mobile line):
In case of using fan lights, TVs, refrigerators or other guest devices with a capacity of less than 1kW, the wire from the electrical outlet or switch to the electrical equipment should be used simultaneously with 1 wire, which is a soft soup wire with a cross section of 2×1. 5 mm2.
Mobile wires for electric stoves, heaters, etc. have a capacity of 1kW to 2kW, so PVC cables with 2 layers of insulation, cross section of 2×2.5 mm2 should be used to ensure both electrical and mechanical safety.
