Power cable fire-proof plants, substations and industrial and mining enterprises are widely used power cables, low-voltage cables, cable once caught fire and exploded, would cause serious fires and power outages, in addition, produce a lot of smoke and toxic gas when cables burning, not only pollute the environment, and endanger the lives of people. Therefore, we should pay attention to the power cable fire. Low voltage cable voltage drop ΔU = Uae-Ube = UR + UL voltage drop ΔU = Uae-Ube = UR + UL, Meixian low voltage cable spot, while UR = IR0, UL = I · jX0, Baoji supply of low-voltage cable, so, ΔU = I (R0 + jX0), with an effective value of the voltage drop ΔU per unit length is: ΔU = Ibe · R20 + X Sang 20 (3) (3) Convert to l (km) length of the line voltage drop is the formula (1). As can be seen, the voltage loss that is after the beginning of the voltage cable to the terminal voltage vector projection vector, the Bin County low-voltage cable outlets, the terminal voltage is higher than the beginning of the voltage reduction amount, that figure BD segment. Since BD = BC + CD and BC = Ibe · R0 · cosΦ, CD = Ibe · X0 · sinΦ it ΔUф voltage loss value is: ΔUф = Ibe · R0 · cosΦ + Ibe · X0 · sinΦ = Ibe (R0 · cosΦ + X0 · sinΦ) (4) (3) and (4) are voltage drop and voltage loss value of each phase, to be converted into a line voltage drop and line voltage loss value, shall be multiplied by Formula 3. The formula (4) is converted to the line voltage loss value, and then compared with the rated line voltage, and multiplied by 100%, that is, the percentage of line voltage loss formula (2). Low voltage cables, cables in the Middle East, gold power cables, low-voltage cable factory in Xianyang in Shaanxi Baoli cable provided by the Company. Shaanxi Baoli Cable Co., Ltd. (www.jinlidl.com) (www.jinlidl.cn) is a professional, "Wire and Cable, the Middle East cable, gold power cables," the company. Since its inception, we adhere to the "good faith, sound management" approach, the courage of healthy competition in the market, so that the "golden power cables, the Middle East and cables," the brand has a good reputation. We adhere to the "service first, customer first" principle, the Middle East and cable, power cable Kim won the customer's trust in the power cable in the congregation, and establish a good corporate image.
