For industrial and mining enterprises, energy and transportation sector, for the AC rated voltage 450/750 volts below the control, protection and other occasions the use of PVC insulation, PVC sheath control cable.

Performance characteristics

DC resistance: 20 C, 0.4mm copper wire, less than equal to 148 /km, 0.5mm copper wire, less than equal to 95 /km.

Dielectric strength: 1kV 1min between the conductor and the shield 3KV 1min does not breakdown

Insulation resistance: each core wire and the rest of the wire grounding, control cable is greater than 10000M.Km, HYAT cable is greater than 3000M.Km.

Working capacitance: the average value is 52 + 2nF/km

The distal crosstalk ratio: the specified combination of average power value is greater than 69dB/km 150kHZ.

Performance difference

The power cable is used to transmit and distribute the high power electric energy in the main line of the power system, and the control cable can be directly transmitted from the power distribution point of the electric power system to the power supply connection line of all kinds of electric equipment. The rated voltage of the power cable is generally 0.6/1kV and above, the main control cable is 450/750V. The same specifications of the power cable and control cable in the production, the power cable insulation and sheath thickness than the control cable thickness.

(1) the control cable is a kind of electric cable and power cable, which is the 2 of the five major types of cable.

(two) the standard of the control cable is 9330, the standard of the power cable is GB12706.

(three) control cable insulation wire color is generally black and white printing, low voltage power cable is usually color.

(four) the control of the cable section is generally not more than 10 square, the main power cable is the transmission of electricity, the general is a large section.

Due to all of the above mentioned reasons, the specifications of the power cable can generally be large to 500 square (conventional manufacturers can produce range), another big section generally do manufacturers is relatively less, and control of cable section is generally relatively small, most commonly less than 10 square.

Speaking from the cable core number, power cable according to the requirement of the power grid, most generally 5 core, and control cable transmission control signal, the number of core, according to the standard of a 61 core, but also can according to user requirements production.
