Working capacitance: The average value is 52±2nF/km5. Far-side crosstalk defense: 150kHZ, with an average power exceeding 69dB/km. Differential control cables are waterproof, corrosion-resistant and damage-resistant, and can be laid in tunnels or cable trenches. Engineering cables are used on the main line of the power supply system to transmit and distribute high-power electromagnetic energy. The Control cable instantly transfers power from the power system software's power point to the power electrode connections of various appliances and home appliances.

The rated current of the power cable is generally 0.6/1kV and above, and the key working voltage of the control cable for 450/750V. When manufacturing power engineering cables and control cables of the same specification, the insulation and sheath of power engineering cables are thicker than control cables. Control cables are cables used in electrical equipment, and power cables are two of the five types of cables.

Control cable size is 9330, and power cable size is GB12706. The color of the insulating cable core of the control cable is generally gray-black with a milky white mark, and the low-voltage line of the power cable is generally toned. The cross-section of the control cable is generally not more than 10 square meters, and the power cable is mainly suitable for power engineering transmission, and the cross-section is generally larger.

Because of the above reasons, the specifications and models of power engineering cables can generally be higher, up to 500 square meters (traditional manufacturers can manufacture), There are generally fewer manufacturers that can make higher cross-sections, and the cross-sections are higher. The number of control cables is average. In terms of cable types, according to the regulations of the State Grid, power cables are generally five-core, while control cables are used to transmit control data signals, and there are many types of cables. According to specifications, it has 61 core technologies, but can also be manufactured according to customer requirements.
