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 difference between VV22 and VV62?
- Cable flow current is to be hot, look at the table with a look at the current is normal, the current is consistent with the cable configuration. Laying the environment is normal.
- Q:Whether high voltage cables can be built in belt corridors
- Power cable accessories are divided into several types, commonly used is heat shrink cable accessories, cold shrink cable accessories. (1KV, 10KV, 20KV, 35KV), several models (indoor, outdoor, intermediate connection), each containing the components are not the same, but there are all kinds of cold Heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable tube, sealant and other operating accessories.
- Q:Cable yjv-0.6 / 1kv-4 * 120 + 1 * 70 What does it mean?
- To use the video card at the same time connected to the computer monitor and TV show together, have to do the following: 1) graphics card must include HDMI, including two or more signal output interface. (Such as the shadow GTX650 there are DVI, VGA, HDMI three signal output interface.) As long as the graphics card to meet this requirement, no matter which brand can be. 2) graphics card HDMI interface has to support the original sound decoding, that is to say with the HDMI cable and TV connection will have a sound output. 3) in the TV or computer monitor line to use straight, can not transfer. Because a card when the transfer may not show. 4) After installing, enter the display adapter from the Start menu. The contrast display to set, to show the same content to select the copy; to display different content on the choice of expansion on it.
- 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: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:With a i3-2100 desktop computer about how much money. To have a separate graphics card. Give a configuration alone, no more than 4000
- The length of the cable bracket is determined by how much the cable is
- Q:What does the cable ZR-YJV22-4 * 16 mean?
- Copper core XLPE insulated PVC sheathed flame retardant power cable, three core, nominal cross section 6 square millimeters, rated voltage 0.6 / 1kV, model specification specification: ZR-YJV0.6 / 1KV3X6mm ^ 2.
- 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:Lighting wire, I do not know is it. The When to use BV1 * 2.5, when to use 2 * 2.5, when to use 3 * 2.5, when to use 4 * 2.5,
- It does not look good, but also affect the wallpaper, wallpaper, in full swing, and then from the chain reaction, then it is worthless, it is recommended to use decorative decorations decorated, perhaps alone for more suitable wallpaper pattern or color ... that does not affect the wallpaper Can also play a decorative effect ... Thank you
- 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
