What role does wire and cable shielding play?

I. What role does wire and cable shielding play? Measures to prevent or mitigate electrical interference, there are mainly the following three aspects.1, a spare core of the control cable grounding Practice has proved that a spare core in the control cable grounding, the amplitude of the interference voltage can be reduced to 25% ~ 50%, and the implementation of simple, and the cost of the cable increases very little.2, the electrical interference will occur when the circuit of the serious consequences of the control cable is not suitable to use a control cable. These include: (1) weak signal control circuits and strong signal control circuits; (2) low-level signals and high-level signal circuits; (3) AC circuit breaker phase-by-phase operation of each phase of the weak control circuits, should not use the same control cable. However, the weak circuit of each pair of round-trip wires such as belonging to the control cable is not the same one, in the laying of the ring may form an arrangement, in the proximity of the power supply of the electromagnetic line cross-chain will be generated under the potential, the value of the weak circuit of the parameters of the low-level interference may have a greater impact on the weak circuit, so the round-trip wires should still be used together with a control cable is appropriate. 3, the metal shielding and shielding grounding metal shielding is to weaken and prevent electrical interference, an important measure, including the core of the wire to prevent electrical interference, the metal shielding and shielding is an important measure. Important measures, including the total shielding of the core, sub-shielding and double-layer total shielding. Control cable metal shielding type selection, should be based on the strength of the possible effects of electrical interference, counting the comprehensive measures to suppress interference, in order to meet the requirements of reducing interference and overvoltage. The higher the requirements for the effect of anti-interference, the greater the corresponding investment, when the use of steel tape armor, steel wire braid total shielding, the price of the cable increased by about 10% to 20%.
