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)

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.

- Q: Hi, my old laptop has broken: when i try to put the power cable into the socket on the laptop, it only goes in on a certain angle and never stays there even when taped, so its impossible to get the laptop on for more than a few seconds. I've tried different power cables too, and nothing seems to work, so it must be the actual laptop problem... how can I get the laptop to stay on to retrieve some photos that I have got on there? Thanks
- you will no longer get lots money for a computing device without stress. right here is what to do: (a million) purchase a caddy ( a container that turns the stress into an exterior USB stress) ?10 - ?20 (2) take the stress out of the previous device, positioned it in the caddy, connect it to a distinctive computer (3) use the different computer to wipe the stress (4) flow the stress back to the computing device (5) sell the computing device (and the caddy, in case you do no longer want it; notwithstanding that's properly worth conserving it for emergencies).

- According to the specification requirements: 8.10 cable bridge wiring 8.10.4 cable bridge horizontal laying, should be selected according to the load curve to support the best span, span should be 1.5-3m. Vertical laying, the fixed point spacing should not be 2m. Assuming that the height of the electrical shaft is 60 m and the fixed point spacing is 2 m, then the number of stents required is: (60/2) * 2 = 60 Assuming that the height of the electrical shaft is 60 m and the fixed point spacing is 1.5 m The number is: (60 / 1.5) * 2 = 80 mainly depends on your shaft height, and the bridge fixed point spacing, hope to help you, (* ^ __ ^ *)
- Q: How do I get it not to do that? Its really annoying. Whenever I remove the charger cable , the screen gets really dark. It seems like an actual function and not a defect, but is their a way to toggle it on and off?
- Thats how its made. Laptops dim screens to save battery power. To override the setting, look for a picture of the Sun on the middle-top of your keyboard. Sometimes its Blue. Once you find it, look at the bottom left of your keyboard for a FN (function) button. While holding the FN button, tap a few times at the sun button. Your screen should now be bright ;) Make sure you do this with the power unplugged, enjoy.
- Q: I used my laptop as a home computer, most of the time I keep my laptop turned on with the power cable plugged in. Is it good to do that? or is it better to plug the power off whenever the laptop's battery is full? Which one is good for my laptop' maintenance? By the way, everytime I asked this question, people give different answers. So I really need a professional opinion.
- I'm not sure what's best for your actual laptop but I just had to order a new battery for my mobile phone and laptop the other day. The guy at the battery store told me it's better to charge it up, then let it run all the way down or as close as possible to empty before charging up again. He also said you should only charge them for as long as it takes to fully charge. Apparently batteries create a 'memory' from where you start charging them so that if you charge them as soon as they get to half full they'll 'remember' that eventually and as soon as they reach half full, they'll 'think' they're empty. Well that's what he told me. That's what's best for your battery, if I were you I'd just ring a computer store and ask an IT tech this question instead of asking idiots like us.
- Q: Whether high voltage cables can be built in belt corridors
- Cable bridge spray to improve the corrosion resistance and anti-aging. Spraying the cable tray is the electrostatic powder coating equipment to spray the powder coating to the surface of the bridge, under static electricity, the powder coating will be evenly adsorbed on the surface of the cable bridge to form a powder coating, powder coating layer through the high temperature baking flow Flat and cured, into the effect of different (different types of powder coating effect) the final coating. Spraying effect in mechanical strength, adhesion, corrosion resistance, aging resistance and other aspects are better than the painting process, the bridge body metal can play a good protective effect, the cost is also under the same effect of paint. The basic principle of electrostatic spray technology is the static generator to produce negative high pressure (10KV or so), the use of corona discharge phenomenon powder coating (a variety of colors) adsorption on the metal parts, powder coating by the supply system by compressed air Nozzle, the front end of the nozzle with a high voltage generated by the high voltage static generator, due to corona discharge, in the vicinity of the dense charge generated by the powder from the nozzle when the formation of charged paint particles, it is the role of electrostatic force , Is adsorbed to the metal parts up, after heating the powder melting, and natural cooling curing, in the workpiece surface to form a hard coating. This kind of spray cable tray is made of this.
- Q: I have a yamaha dgx-300 keyboard, and lost the power cable to it about a year ago. Do any stores like circuit city or something carry a power cord that would be compatible with my keyboard?
- Here are two adapters for your keyboard, your manual or a sticker on the keyboard, should tell you which one you need.
- Q: How can you tell which lines on telephone poles are power lines, cable lines, and phone lines?
- The higher they are up, the Higher the voltage. Of course, high voltage power will usually have individual bare aluminum conductors on porcelain or plastic insulators. Lower voltage (120/240 in North Amercia) is either three or four conductors on a set individual insulators, or two or three insulated wires wrapped around an aluminum wire (steel cored actually). The 4th wire, if there, is for street lights. Telephone is a think cable, with junction boxes evert few homes, which the customer lines come off of. Cable lines are a round coax, which connect to its pole equipment with threaded connections, usually with hex fittings, and splitter/taps which customer lines conenct to. Cable lines also have power injector boxes every often. They supply the power for amplifiers. If the wires are overhead to a home, you can usually tell by what they connect to. Electricity is obvious, the individual conductors from the lateral connect to the individual conductors on the drop, which lead to the meter. Telephone and cable both usually go to similar boxes on the house, but cable continues with one or more of similar coax, while telephone goes in with a JKT, Cat 3, or 5 cable, often grey.
- Q: i have a 97 chevy malibu and i need to know where to run the power cable through the fire wall. or where could i get a diagram that is simple enough for me to understand...
- Either find a rubber boot with enough space through it (where your steering column goes through), or drill a hole and use the grommet that comes with your Amp Install kit. If you choose to drill, MAKE SURE you have enough clearance on both sides.
