Q:W22 in the cable on behalf of what
Oh, not W it should be VVVV22 is the meaning of plastic insulated plastic sheath with armored copper cable
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:Will the two 16 square copper wire with what specifications of the trunking
WZC: W-halogen-free, ZC-flame retardant class C F46-poly perfluoro-propylene propylene Y - polyolefin sheath 2 - steel tape armor 2 - PVC outer jacket
Q:What is the meaning of "cable tray: 200 * 100 middle strip" in electrical engineering
In addition to considering the security issues, there is no problem, you can use this, there is no impact on the charging situation, rest assured
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:Power cable 5-color line, respectively, what color, what role?
YJ: XLPE insulation V: PVC sheathed 22: steel tape armor 8.7 / 15KV: rated voltage: 8.7 / 15 kV (phase voltage 8.7 = 15 / 1.. line voltage 15kV) 3 * 300: Three conductor cross-section of 300 square copper conductor Another: If YJLV is the aluminum core. Here is not marked what the material is conductor, you can default to copper conductor.
Q:Where the computer can be a bare chassis. Which hardware inside the framework
It is best not to use this, because you have no way to test the signal line. There are special 10 line 8 line terminal telephone switch patch panel
Q:Power cable yjv22-10kv-3 * 50 what it means
Yj is cross-linked polyethylene insulation, v PVC sheathed 22 is double steel tape armored, voltage 10KV, 50 square three-core copper cable
Q:1omoons / days sensitive quad-core network set-top boxes can be used on old-fashioned televisions.
Set-top box on the TV next to a method is to use the network cable connected to the computer, another method is in the set-top box next to a wireless router, the computer can not be used to use the network, if there is no dark Set the network cable, you can also use the power network adapter to the network set-top box out of the network cable connected to the power adapter, through the power line to connect the computer Internet. As long as enough 4M, regardless of rural or urban are the same, I now use the 4M broadband, basically not card.
Q:What kind of material should be selected for the fixing bracket of the cable trunking
General 2.5 square wire load is 2 kilowatts, and rubber sheathed cable, full load can reach 3 kilowatts are no problem (estimated again, it is not safe). The load level of the wire is mainly dependent on the current, but also on the voltage level. Under normal circumstances 50A below 1 square millimeter safe carrying capacity is 6A, 50 ~ 100A current 1 square millimeter of the safe carrying capacity is 5A, 100A current above the general take 1 square millimeter of the safe current is 2.5A; so many large square copper cable You can calculate the current. According to the three-phase alternating current formula: P = 1.732 * U * I * cosφ, cosφ is the power factor, select 0.8; this is the three-phase power calculation formula. Single phase: P = U * I * cosφ, cosφ is the power factor The power factor is 1 for the resistive load and 0.8 for the inductive load.
