Electrical performance test of ferrule type cable mesh from buzai232's blog

ferrule type cable mesh it mainly includes conductor DC resistance, insulation resistance, finished product voltage test and voltage test between insulated wire cores, each of which is very important. Conductor resistance directly reflects the electric transmission performance of the cable, and directly affects the temperature, service life, voltage drop and operation safety of the cable during power on operation. It mainly checks the material and cross-sectional area of the conductor. If the material of the conductor is not good or the cross-sectional area is serious Insufficient, it will cause the conductor DC resistance seriously exceed the standard, this kind of cable laying in the line will increase the loss of current passing through the line, cause the cable conductor itself to heat, cause the insulation aging cracking of the coated conductor, cause the power supply line leakage, short circuit, and even cause fire, endanger the safety of people and property. The standard has strict regulations on the conductor DC resistance value of different specifications of cables, which shall not be greater than the value specified in the standard.To get more news about ferrule type cable mesh, you can visit boegger.net official website.

Insulation resistance, finished product voltage test and voltage test between insulated cores all examine the electrical insulation performance of cable insulation layer and sheath layer. Insulation resistance is to detect the resistance of insulating material between two conductors, which should be large enough to play the role of insulation protection. The finished product voltage test and the voltage test between insulated cores not only require the cable to have enough insulation capacity, but also require the insulation or sheath material to be uniform without impurities, the thickness to be uniform enough, and the surface to be free of invisible trachoma, pinholes, etc., otherwise it will cause local breakdown during the withstand voltage test.
