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 are the requirements for the spacing between the strong and weak wires?
- with a white cable to facilitate the distinction between the cable
- Q:The TV shows no signal. The What is the reason for this?
- We usually say how many square millimeters (wire) refers to the cross-sectional area of the wire core, that is, according to the diameter of the core calculated cross-sectional area. The larger the cross-sectional area of the wire, the greater the capacity of the power transmission.
- Q:Why does the sparrow stand on the wire without electric shock?
- the network patch panel is now more mainstream network system patch panels, generally every 1U height can accommodate 24 8-core network port, back line, front jumper plug in addition, look at the Google Encyclopedia on the 110 patch panel instructions, found a little problem, that is 110 patch panel documents, but the picture is not 110 patch panels, that should be called Kelon, we also Called this thing for the VDF, it should be noted that the 110 system is AT & amp; T, that is, Lucent (Lucent) company's standards, and Kelon is the German Kelon (kelone) company's standard, not the same thing, Dragon frame is generally used in large-scale voice wiring system, and generally fixed for the wall, if placed in the standard cabinet will have to install the backplane, the Kelon frame steel frame fixed on the backplane The 110 patch panel is a standard 19-inch equipment, can be directly fixed in the standard 19-inch cabinet As the 19-inch standard cabinet has been widely used in the civilian areas, so Kelon is now less application, mainly in the use of operators these with a number of tattoo and fat ancient mix of full-chip cable is integrated wiring system in the most basic connector, the product range is also very much on the market, of course, there are many changes in the form On the use of network patch panels and 110 patch panels, Google Encyclopedia and the library have a detailed description, you can refer to
- Q:Choose the configuration of good or bad computer graphics card memory processor, etc., how to choose a different manufacturers
- Is not the power cord is loose, or is the motherboard battery power
- Q:The UV lamp is fitted with ozone and no ozone difference
- Man, your weak tube is not quite long? If the length of the pipeline is very long, you need to wear the wire, unless you have no wire can be threading method. Your length of the pipeline is very long, in the tube when the tube has been added? There is no wire box to make up.
- Q:Where the computer can be a bare chassis. Which hardware inside the framework
- Depending on how much of the 24 switches that U ah, 1U, then up to 42 slightly, but still empty position good heat dissipation, 2U, then installed a 20 up to the bar.
- Q:TV tiger when the set-top box when tv / ay look for a look on the platform
- . the first two said two cables, KW is KVV that PVC insulated jacket control cable. . the control cable for industrial and mining enterprises, energy and transportation sector, for the exchange rated voltage 450/750 volts below the control, protection lines and other occasions, the use of PVC insulated, PVC sheathed control cable. . the performance difference: the power cable in the main line of power systems used to transmit and distribute high-power power, control cable from the power system distribution point of electricity directly to a variety of electrical equipment, power equipment, power lines. The rated voltage of the power cable is generally 0.6 / 1kV and above, the control cable is mainly 450 / 750V. The same specifications of the power cable and control cable in the production, the power cable insulation and sheath thickness than the control cable thick.
- Q:What recycled rubber is suitable for the production of wire and cable?
- Symmetrical receptacles need to be treated differently, with color distinctions most convenient.
- Q:What is the warranty period for wire and cable?
- General cable shelf life is 10 years, look at the jacket and the insulation with or without cracks, shake the insulation resistance of the general do not breakdown can be used, but the best people to do some pressure test. The withstand voltage test must have been used.
- Q:1omoons / days sensitive quad-core network set-top boxes can be used on old-fashioned televisions.
- Pipe protection cable to wear metal hose, metal hose and galvanized pipe to use metal lock connection, the connection can not pull the light pull on the line. If there is no metal hose or no metal lock, in the pipe when the pipe toward the cable to the appropriate bending, preferably in the mouth of the cushion cable skin, and then use the electrical adhesive tape sticky, sticky. After the nozzle cut with a polisher smooth grinding, the provincial scratch cable.
