I. Characteristics of the cables
1. Using factory prefabrication methods can substantially reduce the site construction labor intensity and shorten the construction laying time;
2. Use of cables can guarantee great length and bending property, and greatly facilitates the construction in a complex place;
3. Use of cables reduces the laying space, and cables can be installed together with gas and hydraulic gas pipelines;
4. Their reliability and reliability can be fully guaranteed, for the cables are manufactured in the factory,
5. Sub-branch parts should use high strength sealed joints, which are waterproof and have properties of moisture protection, long-term maintenance and free for repair;
6. Because the cables are directly connected with households with no need of maintenance and repair and with easy and simple construction, the cables can produce significant comprehensive economic benefits.
II. Usage of the cables:
1. To be used for high-rise building;
2. To be used for disaster prevention equipments;
3. To be used for tunnel lighting and disaster prevention equipments;
4. To replace copper bus bar with small or medium capacity in various places.
III. Standards of the cables
IEC 60502 Rated Voltage 1 ~ 30KV extruded insulated power cables and accessories (International Electrotechnical Commission standards)
GB 12706 Rated voltage 35KV and below Copper core, Aluminum core plastic insulated power cable (National Standard of the People's Republic of China)
JCS 376 branch cable (Japanese Electric Wire Industry Standard)
General Rules for JIS C2810 indoor wiring electrical connection pipes (Japanese Industrial Standard)
Types of the cables:：
Standard main cables and branch cables are all low-voltage power cables with XLPE or PVC insulation materials (IEC, GB, JIS, BS ... ...), and PVC materials covered on the outer side. Generally, the main cable is single-core or twisted multi-core cable (cables with two to five cores), the branch cables are single-core cables, and may adopt a fire-resistant, flame retardant cables in accordance with the requirements.
Their structures and types are as follows:
three cores twisted type
four cores twisted type
five cores twisted type
PVC insulated PVC sheathed branch cables
PVC insulated PVC sheathed flame-retardant branch cable
PVC insulated PVC sheathed fire-resistant branch cable
Cross-linked polyethylene insulated PVC sheathed branch cables
Cross-linked polyethylene insulated PVC sheathed flame-retardant branch cables
Cross-linked polyethylene insulated PVC sheathed fire-resistant branch cable
- Q:What is the use of wire and cable per square meter of residential building?
- You can use sc. if too long, or bend the best use of the bridge
- Q:Will the computer master, external DVD burner how external power supply, please click details. Thank you!
- You can shop on the ground floor of a layer of waterproof carpet (that is, the rural common 'kang seats'), the wire shop in the following, at the desk to stay a outlet hole, and the jack or electrical connection. Carpet can be bought in the hardware building materials store, as the traces of tape, you can go to the big supermarket to buy a special scrub, ask the salesman on the line. Wish you the best at work
- 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:A sub-eight splitter, behind the link ONU equipment, which also need to add fiber patch panels, or can be directly connected?
- How do you not say that the three-phase system or two-phase system, if the two systems is the power in addition to the voltage is equal to the current, three-phase power per kilowatt multiplied by 2 equal to the current, such as 220V, 3000W / 220V = 13.6A, 380V, 3KW * 2 = 6A. Wire 10 square below, each square can be with 5A, which is the calculation of aluminum core line, copper wire line operator count, 220V aluminum core must be greater than 2.5 square, copper core must be greater than 1.5 square, 380V with aluminum core The line must be greater than 1.5 square and the copper wire must be greater than 1 square. At this time should also consider the equipment to start the current and increase the appropriate diameter.
- Q:What is the wiring principle in the home improvement circuit?
- This is not the end of the family with a good audio and video lines are thousands of dollars I do not know what kind of advice you want to go to the local workers Duan Gengmang Gama moths tied to the supermarket stall can find!
- Q:Computer host configuration of about 1,000 yuan (preferably 1000 below) - probably as follows;
- "Electrical design of civil buildings," 8.10.13; steel cable bridge straight section length of more than 30m, aluminum or glass fiber reinforced plastic cable bridge length of more than 15m, should be set up expansion joints. Cable bridge across the building deformation joints, should be set compensation device. The telescopic section is set for temperature change; the compensating device is to prevent settlement at the deformation.
- 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:Wire inside the two lines, red and black, black line is the line of fire or zero line ah?
- According to the size of the product to open a good plastic mold and then purchase the plastic raw materials to be injected (raw materials depending on your product requirements, advanced point will use To the engineering plastics PE, PS, etc, and even to join the flame retardant, fiber material), the difference is like now with the charger on the use of only PVC3 Called the wire manufacturers according to your request to do a good line Of course, you have the conditions you can pull the wire of their own beer process: mold on the machine (ingredients test mode) --- welding wire and hardware (pin) --- then put the welding hardware on the mold (according to the mold Put five to ten range) - boot molding - detection of another: If you want to have all the country's certification, it is estimated that you no technology is not too, you can not buy that hundreds of thousands of equipment to detect The power line in the material composition and a variety of techniques to wear flattened Fenbao match platinum standard, because the formal power It is too much to be recognized, but you want to do ordinary DC line, such as mobile phone charger or no problem, but the regular factory what automation machine to do, then I do not know, but it is automated machine estimates But also the cost of scary Anyway, ordinary manufacturers do have any questions can EMAIL: qingxinghe@21cncom Do not call me in Google, I rarely said so much, add points to me, huh, huh
- Q:What is the power cable accessories used to do?
- Do not know what you want to ask? What about your situation? Normal or pregnant? Normal this radiation does not affect what, if it is pregnant, this is far away from the best. Pregnancy is most needed to stay away from the microwave!
