power cable is the main line of power system,
for the transmission and distribution of electrical energy.
rated voltage is generally 0.6 / 1kv and above.
the power supply is directly transmitted by the control cable to the power supply equipment,
the rated voltage is 450/750v.
this makes the time of production,
power cable insulation and sheath thickness ratio control cable thickness.
the difference is summarized as follows:
a control cable belongs to the electrical equipment cable,
and the power cable is the five major categories of cable in the 2.
two. the standard of control cable is 9330,
power cable standard is gb12706
three, control cable insulation wire is usually printed on the black color,
there are low voltage power cables are generally color separation.
four, control cable cross-section will not exceed 10 square,
power cable is mainly the transmission of electricity, are generally large cross-section.
