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:Can i connect 8 pin power cable to a 4 pin power connector?
- This is about power connector -
- Q:Can I mix different power cables / transformers for different electronics? The plug does fit in.?
- uk is now 230, the ecu voltage. (easily, capacity is transmitted under the Channel from France throughout the frenzy hour, that's a risk simply by fact the Continent is on needed ecu Time; no longer correct on your question yet exciting.) some electronics bought interior the USA of a are marked one hundred twenty˜240 and those could be utilized interior the united kingdom with basically a plug adapter. Hair dryers and another home equipment have outfitted in resister circuits and you will pass a swap from one hundred twenty to 230/240. or you elect a converter (no longer reported by way of many electricians different than as an emergency holiday expedient) or a transformer. you may desire to examine up the wattage or amperage or you will burn out the transformer. For digicam battery chargers etc, interior the no longer likely experience they are not twin voltage, you may positioned them interior the one hundred twenty v. socket of a batheroom shaver outlet (those have circuit breakers in them for a million amp or much less). I easily have not viewed any digicam chargers recently that are no longer twin voltage. yet confirm. you need to purchase adapters to extra healthful the unique British electric retailers in drug and equipment shops throughout Britain, and at airports.
- Q:LCD TV/Cable Power Issue?
- Something is seriously wrong, and you may need to get an electrician on the problem. You need to check the voltage between your set and the cable with a meter. There should be little or no measurable voltage. If you are getting a reading like 115 volts, then I suspect that the wall outlet into which your TV is plugged has been wired backwards, i.e. the black wire is on the white terminal, and vice-versa. The cable is (or should be) grounded where it comes into the house, but if the outlet has the hot wire on the wrong side, this might cause the problem you described. The wrong connection could have occurred anywhere along the line between your main panel and the outlet, so this may involve checking the connections at several outlets and light fixtures - whatever is on the same circuit as your TV's outlet.
- Q:Xbox 360 power adapter cable change?
- How might I replace it if i've got not got it linked to the internet? i think of you may obtain the replace and placed it on a flash force. How might I hook up with the internet? I don’t have a instant router, basically the Nintendo wireless usb connector for my wii. am i able to basically use cables/cords? particular it has an the two internet twine. Is on line unfastened? i think of silver is, and that i comprehend Gold is $50 in line with twelve months. particular, yet once you do the mathematics, and are available across a good deal you will get 13 months for around $40. What are the failings you're able to do and purchase on line? in general like gamer maps, there are gamer photos and subject concerns to your xbox. (those are not fairly worth it) in general upload ons for video games, or purchase archade video games. If/whilst i'm able to circulate on line, what are some on line useful properties? You play agasint others on line, you may obtain demos faster. whilst employing XBLA do the video games you purchase circulate on on your memory card/hardrive or do they stay on line after procuring it/basically play it on line? They circulate onto your perplexing force. Can Xbox arcade even use the XBLA/industry or circulate on line? i don't think of so. i think of you choose some memory card or perplexing force. Are you satisfied with yours? very plenty so! (the different questions digital mail me)
- Q:My computer will not boot unless I unplug the power cable for several minutes and replug the power. Causes?
- this sounds like an electrical problem. not a software problem. you may need to test and/or replace your power supply. or check the outlet that you're plugging it into. it may have gone bad and the computer is just reacting to it. try using another outlet that's maybe not on the same circuit. like in another room. if it still does the same thing then it's probably your power supply that has become damaged.
- Q:Amp/Sub question; power wire/RCA Cables/speaker cables placement?
- Separating the power the speaker wires is not as important in a car that uses DC voltage as it is in a home system that has AC voltage. It certainly doesn't hurt anything, tho.... If you do run them across each other, keep the intersection as close to a good right angle as possible. And, air is a very good insulator, so keeping some distance between the power the speaker wires is also very good.
- Q:How to add power and cable outlet to closet?
- if you mean a shower room then you cannot put electrical sockets in as it's illegal. Similarly you will blow the equipment up when it gets wet.
- Q:Do ferrite beads on audio leads and power cables do anything meaning full?
- Generally they are fitted to fix a narrow bandwidth issue, so you would need to know what interference issue you are trying to fix. In most coaxial application this is for the roll off between shielding types.
- Q:Does the ps4 and ps3 have the same power cable?
- Yes it does Adding to that, you need a TV with an hdmi port Also, the power cable doesn#x27;t come with a brick like the Xbox one does
- Q:Transoceans fiber optical cables need signal boosting. How are boosters powered?
- The repeaters use copper wire bundled together with the fiber optic to power the repeaters, the voltage drop is managed with an engineered choice of voltage and current. Each cable has a different combination to suite the particular distance. And each cable would be tailored for the individual application.
