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:Which has, know the power of the electrical, choose the cable formulas. And explain it
The audio line to use a shield of the special line, shielded cable and TV open to the road, the state is 1 to more than the signal line, the outer layer of metal mesh, with this line It will be disturbed.
Q:Will the two 16 square copper wire with what specifications of the trunking
How to say that interference is certainly some, if you line less words on one or two in the bridge next to do a tube it! The pipe will be a little better. Upstairs that I do not think that although in practice the construction of this practice a lot, because you do not feel the interference, but the reality does interfere with, or science should not be strong and weak must be separated.
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:PVC pipe on the GV.215-16 (C) What does it mean
SC pipe welding fluid with welded steel pipe, the general thread connection, or casing welding connection. TC pipe is a thin-walled steel pipe, referred to as wire tube, you can thread connection, tight connection, buckle type connection, not casing welding connection.
Q:What does the cable ZR-YJV22-4 * 16 mean?
ZR-YJV1KV6mm ^ 2 * 3 for the copper core flame retardant XLPE insulated PVC sheathed power cable, three core, nominal cross-section 6 square millimeters, rated voltage 1kV, model specifications specification: ZR-YJV1KV3X6mm ^ 2.
Q:What is the difference between a trough bridge and a tray tray?
The line is to be reserved, the installation will have a certain degree of tightness
Q:Can cable TV signal lines and network cables be placed in the same line when upgrading? What happens if you are in the same line? Thank you.
Sub-strong electric power cable control cable transmission cable and so on
Q:Power cable YJV22-8.7 / 15kv-3 * 300 what meaning
Power cable YJV22-8.7 / 15kv-3 * 300 Meaning: refers to the copper core XLPE insulated double steel tape armored PVC sheathed power cable, cable rated working voltage 8.7 / 15KV, cable for the three-core, single Conductor cross-sectional area of 300mm2. YJ: cross-linked polyethylene insulation V: PVC sheathed 22: steel tape armor 8.7 / 15KV: rated working voltage 8.7 / 15 kV 3 * 300 Specifications: YJV22-8.7 / 15kv-3 * : Three conductors, single cross section of 300 square feet.
Q:What is the role of patch panels generally, why should the switch connected?
If you are in a small city or town, go to some of the aluminum core series of cable (if you are in a small city or town), if you are in a big city, ask high, with copper core BV, BVVB, RV, VV series line Better, according to the level of regional economic development to purchase the cable, wire type.
