Main performance of control cable

Control cable performance characteristics

1. Resistance measurement: 20 ℃, 0.4mm copper core, ≤ 148 Ω / km, 0.5mm copper core, ≤ 95 Ω / km.

2. Compressive strength of electrical equipment of insulating layer: there is no penetration between 1kV electrical conductors for 1min, and there is no penetration between electrical conductors and shielding anchoring layer for 3KV for 1min.

3. Grounding resistance: the grounding device of each wire and other copper core cables, and the control cable exceed 10000m Ω Km, HYAT cable exceeds 3000m Ω km。

4. Capacitor in operation: average 52 ± 2NF / km

5. Far side crosstalk defense: the average power of specific components at 150kHz exceeds 69db / km.

The control cable produced by Qingzhou cable manufacturer has the characteristics of waterproof, anti-corrosion and anti destruction, and can be laid in tunnel construction or cable trench. Power cable is the backbone of power supply system, which is used to transmit and distribute high-power electromagnetic energy. The control line immediately transfers the power supply capacity from each distribution point of the power supply system to the power connection lines of various distribution facilities and household appliances. In general, the rated current of power cable is 0.6/1kv and above, and 450 / 750V is mainly used for control cable. The insulation resistance and sheath ratio of power cable control the thickness of cable, which is used to produce and manufacture power cables and control cables of the same specification and model.

(1) Control cable is a kind of cable for electrical equipment, and power cable is two of the five types.

(2) The specification of control cable is 9330 and the specification of power cable is gb12706.

(3) The core color of control cable insulation cable is generally gray black or milky white, and the low-voltage color is generally used for power cable.

(4) The cross-sectional area of control cables usually does not exceed 10 square meters. Electric cables are mainly used for power engineering transmission and usually have a large section.
