1000 kW 600 m cable to use much
Three-phase 380V, 1000 kilowatts load, the working current is about: 1899A. The total area of copper cable is not less than: 1200 mm2 copper cable. . the cable is usually a few or several groups of wires (at least two each) twisted from the rope-like cable, each group of wires are insulated from each other, and often around a center twisted, the entire outer package Highly insulated cover. Cable with internal power, external insulation characteristics. . the cable has power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire cables, marine cables, mining cables, aluminum cables and so on. They are composed of single or multi-strand wire and insulation layer, used to connect the circuit, electrical appliances and so on.
1000kw ah that with three groups of 400-ping line should be no problem
Depends on the load is emotional, resistive, should be too long cable, consider the pressure drop. Generally consider 2.5 or more.
Such a large load so far away, can only be transported with 10KY, near the installation of the transformer Caixing, if the 380V transmission, cross-sectional area, high cost, loss of large, not worthwhile. 10KV high-pressure delivery, current 55A, with 25mm? copper cable 35mm? aluminum cable delivery on it. If the 380V transmission, according to the line voltage loss simple calculation formula △ U% = PL / CS take △ U% = 5 copper cable S = PL / CS △ U% = 1000X600 / 77X5 = / 385 = 1558mm? aluminum cable S = PL / CS = U06 / 46X5 = / 230 = 2307mm? Line voltage loss △ U Simple calculation formula △ U% = PL / CS △ U% - Percentage of voltage loss P - Active power of conveying (Kw) Distance of L- M) C-constant, aluminum single-phase 8.. aluminum three-phase four-wire 46; copper single-phase 12.. copper three-phase four-wire 77S-conductor cross section (mm?)
