Measures to prevent or reduce electrical interference typically involve three main approaches. First, grounding a spare core in the control cable has proven effective. When an unused core is grounded, it can reduce the amplitude of interference voltage by 25% to 50%. This method is simple to implement and only slightly increases the cost of the cable.
Second, for circuits that are highly sensitive to electrical interference, it's advisable not to use standard control cables. This applies particularly to situations where weak signal loops and strong signal loops coexist, or where low-level and high-level signals share the same circuit. Additionally, using the same control cable for different phases of AC circuit breakers may lead to induced potential when laid in a loop, causing interference. To avoid this, it's better to use a single control cable for return conductors of weak current loops.
Third, the use of metal shielding and proper grounding is crucial. Metal shielding—such as total shielding, sub-shielding, or double-layer shielding—can significantly reduce interference. The type of shielding should be selected based on the level of possible interference and the need for comprehensive suppression. The more advanced the shielding, the higher the cost. For example, steel tape armored and braided shielding can increase the cable price by 10% to 20%.
In strong electric circuits, unshielded control cables may be acceptable unless in UHV power stations or near high-voltage cables. However, for weak current signal control systems, shielded cables are recommended if there's a risk of external interference. If feasible, keeping these cables away from power lines or enclosing them in steel conduits can also help minimize interference.
For control cables used in computer monitoring systems, the choice of shielding depends on the signal type. Switch signals can usually be handled with a total shield. High-level analog signals may benefit from a total core shield, and in some cases, sub-shielding might be necessary. For low-level analog or pulse signals, individual core shields or composite shields are recommended to ensure maximum protection against interference.
