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

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.
