Q:Yjv22 cable laying pipe when the casing with plastic or steel pipe
(4 × 185 + 1 × 95) is the cable specifications, indicating that the cable has 5 cores, of which 4 cores are 185 Square millimeters, one core is 95 square millimeters. General 185 line is the main core, power with, 95 for the ground core, ground use.
Q:Emergency cable T-box and cable distribution box of the information?
1 Ordinary distribution box There is no switch device in the general distribution box
Q:The wall was sideways opened a trough how to do ah?
With steel wire, lead the bend round, but do not let the wire can hold the pipe wall, and sometimes also need two twisted wire, wire over the past OK
Q:The power cable troughs are divided once and twice
The function of the cable connector is used for the protection of the cable
Q:What is the difference between a pre-branch cable and a punched clip?
. soil buried pipe, including weak and fire, should be thick-walled galvanized steel pipe, that is, SC series of steel pipe, the best size is not less than SC. weak professional, decorative professional now basically use thin-walled galvanized steel pipe, that is JDG series steel pipe
Q:What is the radiation of the laser scanning scanner?
Shield For uniform conductive wire and insulated electric field, 6kV and above in the high-voltage power cables generally have a conductive shield and insulation shield, part of the low-voltage cable is not set shield
Q:Hello, ask about how to charge the electric car at home, use a few square millimeters of wire? How high is the demand for family lines, thank you!
What is the current good computer configuration on the market? The price of 4000 yuan or so no more than 4000 assembly parts to write down the price Thank you.
Q:Ask you a question: how the computer CD-ROM power supply 5V and 12V two lines? Another audio and video cable which group?
Cable bridge at both ends to be installed across the ground wire, ground wire diameter can not be less than 16mm2. Wire ends and wire ends of the middle box to be installed at both ends of the ground wire, grounding wire diameter can not be less than 6mm2. Full length bridge with the grounding system connected to not less than 2. Cable bridge is divided into trough, tray and ladder-type, mesh and other structures, by the bracket, arm and installation accessories and other components. Can be set up independently, can also be attached to a variety of structures (structures) and corridor stent, reflecting the structure is simple, handsome in appearance, flexible configuration and easy maintenance features, all parts are required galvanized, installed in the building Outside the bridge, if it is in the vicinity of the sea or belong to the corrosion area, the material must have anti-corrosion, moisture resistance, good adhesion, high impact resistance of the physical characteristics. According to the relevant provisions of the specification, galvanized cable bridge for a good grounding. galvanized cable tray direct board each fixed bolt contact resistance should be less than 0.005Ω, then the cable bridge can be used as a ground trunk (dusting cable tray should not be used as a grounding line), the resistance of each cable bridge can be the following formula Calculate: r = ρ · L / S where: ρ = 15 × 10Ω-6 / cm (20 ℃); L = length calculated by 100mm; S = cross-sectional area of ​​cm2. The unit resistance value of the ladder on the pallet is shown in Table 2. The unit resistance value of the cable duct is shown in Table 3 The resistance of each ladder (or each cable slot) after the installation of the cable tray is the total: R = R (r + 1 / 3r ') where: R - ladder, that is, (cable trough) total length of the total resistance (mΩ); r - ladder unit length resistance (mΩ / m)
Q:What kind of material should be selected for the fixing bracket of the cable trunking
2.5 square copper (green, with the threading tube) theory will be able to withstand about 20A current, consider the pipe, temperature and other factors, so according to the actual can withstand about 3 kilowatts of power. In fact the 2.5MM2 copper wire is generally open 16A can withstand about 3.4 kilowatts of power.
Q:3 (WDZBN-YJV-4x240 + 1x120) cable how to interpret
3 halogen-free low-burn A-class flame-retardant cross-linked insulated PVC sheathed 4 main core per core 24 square millimeters, 1 ground 120 square millimeters cable.
