Control cable, control cable manufacturer in Shaanxi, shielded control cable

Control cable maintenance control cable prices formula is as follows: the weight of copper in copper X = (wire diameter ÷ 2) ^ 2X3.14X yarn root number X8.9X was + 10% copper processing fees. Control cable cable manufacturing materials price = cost + fixed costs + taxes + operating expenses + profit control cables - security measures due to electromagnetic induction interference generated by the electric current. In general, when the near presence of high voltage, high current source of interference, electrical interference is more serious, since the distance between the same cable core is small, the degree of interference is much greater than the immediate vicinity of the cable laid in parallel. For example, a split-phase operation EHV substation circuit breaker control circuit, a three-phase combined with a cable, there had been such an accident, the split-phase operation of the pulse so that other phase thyristor trigger, leading to a three-phase linkage error, later renamed with each separate cable, it does not happen again Malfunction. Another example of a power plant computer monitoring system, since the low level of the analog transmitter signal line and power line in combination a four-core cable, which has caused interference in the signal line voltage to 70V, which is in millivolts The low signal circuit will obviously affect the normal operation.
