Q:Home improvement, the wire specifications generally how to choose? Lighting, sockets, air conditioning with a few square lines? Ground specifications can be lighter than the line of fire, zero line?
Sailing cold drill. The The Cool cold supreme. The The Pioneer (burner). The The
Q:Is the power cable considered a fixed asset?
Is fixed assets fixed assets - machinery and equipment - conductive equipment
Q:What is the use of wire and cable per square meter of residential building?
Generally wear SC65 tube. If the distance is too long, elbow and more, then the choice will be larger.
Q:Power cable inspection, how many meters should be sampled?
in the wide-linked pricing software GBQ40 to achieve, directly enter the corresponding quota, click on the quota below the" standard conversion ", the cable laying five core check , You can achieve the fixed sub-sub-multiplied by the coefficient of 13 For example: YJ - cross-linked polyethylene insulation (insulation) V - PVC jacket (outer jacket) did not mark the conductor material that is the default copper wire, if the aluminum wire should be YJLV4 * 70 + 1 * 35 core (Mm ^ 2) + Neutral core (indicated by "1") × Neutral core cross section (mm ^ 2) CT - Indicates the cable tray in the laying mode
Q:Ceiling on the wire after the tube is the tube on how to fix it on the ceiling?
Or with 6 points to the difference, but almost a few money, but you know when threading, 6 points is absolutely more effort, the line is also effort, the wire protection is also good!
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:How to find the phone number on the 110 patch panel
Cable ends should be marked with cable head symbols, the middle line should also be different from the ordinary wiring. Bv at the beginning of the general wire, with YJV or vv is generally a cable, but not limited to these
Q:What is the fire wire pipe laying? What is the galvanized steel pipe?
Inverter special cable General power cable difference shielding requirements higher, the number of cores is generally 3 +. three lines of the ground line of three symmetrical and phase line intersection. Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on. The inverter will adjust the voltage and frequency of the output power by the breaking of the internal IGBT, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition, the inverter has a lot of protection , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, the inverter has also been a very wide range of applications.
Q:How high voltage armored power cable is grounded
Insulated isolation of the double shield control cable is the outermost armor layer should be grounded at both ends, the inner shield one end of the ground, is conducive to the rapid release of induced current.
Q:3 (WDZBN-YJV-4x240 + 1x120) cable how to interpret
3 (WDZBN-YJV-4x240 + 1x120) cable is a low smoke halogen-free flame retardant (B grade) XLPE insulated - PE sheathed copper core power cable. The model of the cable is usually composed of eight parts: First, the use of code - not marked as the power cable, K for the control cable, P for the signal cable; so the power cable. Second, the insulation code -Z oil-impregnated paper, X rubber, V polyvinyl chloride, YJ cross-linked polyethylene; so for the cross-linked polyethylene insulation. Third, the conductor material code - not marked as copper, L is aluminum; therefore copper. Four, inner layer code-Q lead package, L aluminum bag, H rubber sleeve, V PVC jacket; so for the PVC jacket. . derived code-D no drip, P dry insulation. Sixth, the outer layer code. . special product code-TH wet tropical, TA dry tropical, ZR- (flame retardant), NH- (fire), WDZ- (low smoke zero halogen, enterprise standards); so low smoke halogen-free flame retardant The . rated voltage - unit KV; general cable are marked, the problem is estimated to write missing 0.6 / . the use of: rated phase voltage of 0.6KV, line voltage of 1KV. In the cable, 4 * 240 + 1 * 120 that there are 4 core 240 square copper wire, a 1-core 120 square copper wire.
