2. Product Working Conditions

(1) The Maximum rated working temperature of the cable conductor is 90 °C.

(2) The Maximum temperature of the cable conductor is 250°C, when it is short-circuited( the longest duration time is 5s)

(3) The Minimum bending radius of the cable is 15 times of the diameter.

3. Packaging

(1) The cable drums for delivery should comply with the requirements of JB/T 8137.

(2) The coils of cable should be neatly wound on to the cable drums for delivery. The cable end should be tightly encapsulated.

(3) Only the cable of the same model and specifications is allowed to be wound on to one cable drum.

(4) The cables provided in rolls or bunches should be packaged in a proper way. The weight of every roll should not be more than 80kg.

(5) The cable drum should be attached with the packaging signs prescribed in 8.4 and indicate its right rotation direction.

4. Transport and Storage

The cables should adjust to all the transport means including the water, land and air transport. In the process of transport and storage, great attention should be paid to:

(1) Preventing moisture from entering into the cable.

(2) Preventing severe bending and other mechanical damages.

(3) Preventing high temperature and exposure to the sunlight.

Q: I transferred to a new University this fall as an upperclassman and the neighborhood surrounding it isn't exactly nice. It is sort of rough. I have to park in the neighborhood during the day and walk 4 to 5 blocks to school *usually* and the first week I was there I noticed a pair of white sneakers with a blue stripe thrown over an electrical wire at an intersection, like an exclamation point. A few weeks later, there is another pair of sneakers, white with a RED stripe. My imagination has been running absolutely wild about this.A friend mentioned that this might be gang related. In memorial of someone who died or as a declaration of territory. Thoughts or facts?: There really are a lot of different possible meanings for shoes over a telephone wire. It could mark gang territory or drug availability (even though these are pretty ineffective since police aren't idiots). It could be a memorial to someone who died, but that's a pretty lousy memorial. Or, as it was when I used to do it, it could just be kids having some fun with their old shoes. If you really aren't feeling well about this, you might stop by the police department and ask them if they know anything about it.

Q: Why swallow standing on the wire is not afraid of high voltage current: As the bird's feet are his step on the same high-voltage wire, the distance between the birds and the feet determine the voltage. The distance between the feet of the birds is very small, so the voltage is very small, the equivalent of 0. Do not let the birds electric shock.

Q: How much current can the six square copper wire be able to withstand?: Yes, the composite material of the high-voltage cable clamp, cheaper than the price of aluminum

Q: I have an under-cabinet 13W T5 fluorescent light fixture that is direct wire. I am adding a simple power cord to it. It has a ground wire, and the box says the fixture may employ a grounded-type receptacle and must be grounded to avoid electrical shocks and to ensure reliable lamp startingSo what do I do with the grounding wire? I can't imagine a simple fixture like this--where millions are sold with a power cord--can be that complicated or dangerous?: Use a 3 wire cord for it and plug.

Q: I am installing a new light switch on the inside of an exterior wall in my walkout basement. Because of the floor joists and finished ceiling, the only way I can figure to get the wiring to that location is by punching it through to the outside and running it along the wall and over to the location of the switch. This run will be about 30ft long and go around one corner. My question is: Can I do this with bare UF (outdoor romex) wire? Or will the wire need to be installed in a conduit?: You said circuit breakers. If more then one breaker is tripping you should call an electrician. If just one is tripping and you can turn off the main breaker, take the wire off the breaker and put it on another one. If it trips that one too, you have a short somewhere and should get help. If it doesn't trip that breaker then the you have a bad breaker. If you haven't worked with electricity before, don't even take the cover off the breaker box. Call someone that has.

Q: I am working with electrical currents and I have one battery and one light bulb and one wire. How do I make the light bulb light?: If your dealing with an A.C. source of 115 volts, answers #1 #2 below prevail! It appears your trying to build a power supply even though 5 volts is somewhat strange, make a trip to Radio Shack. In answer to your question, for an experiment, as long as the insulation on the wires have not deteriorated, old wire will work fine. Low voltage below 32 volts is pretty save but STAY AWAY from 115-120 volts a.c. as it causes the muscles to contract and you can't let go of it!

Q: How can I run electrical wire 2700 ft without signifigant voltage drop only 110 volts: Search for voltage drop calculator on the web and find one to your liking. You said 110V. Attached is a link for 120V. Size your wire for about a 3%-5% voltage drop. (3% is preferable). Example: Voltage Phase: 120V 1-phase 1-way length 2700 ft Wire size: 4/0 (use trial-and-error) Wire type: copper Load amps: 15 Calculate results: Voltage drop: 4V Percent voltage drop: 4% Voltage at end of circuit 115.2V I haven't verified that the results are accurate. You will note the large conductor size. If you have twice the voltage available and can run your load on double the voltage, then the amperage will drop in half and the necessary conductor size will drop to one fourth.

Q: Home water heater is 5000W, said the wire is 4 level, you can press the big open? The: 4p is pliers phone line, 6p do not know, you look at the kind of mouth is suitable for it.

Q: Cable model ZB and ZR What is the difference: Cable trough, generally the material of this PVC trough, the width of not more than 80mm, height of not more than 50mm, suitable for the layout of a small number of cables, wires

Q: What is the meaning of the national standard BVR?: Therefore, when the cables are running at the time of power supply, the two power cables are basically close to each other and the distribution of the current is basically uniform Too heavy, ahead of a large area of ??fever burning phenomenon 3 Parallel operation of the cable, the distance between each other to consider the appropriate amplification, so that when a cable failure, it will not affect the parallel use of the cable at the same time burned, which to a certain extent, reduce the power of economic losses The 4 Parallel operation of the power cable, the cable at both ends of the nose and the switch contact with the contact state, regular checks to ensure that the cable and switch connection is good, because the parallel use of the cable mostly in 35mm2 above the conductor resistance per kilometer in the zero Ohm below, the resistance of the order of magnitude in the 10-1 or so, if the cable nose and switch contact is not good, it is easy to lead to a switch at the cable of a phase or a few phase contact resistance is too large, resulting in two cable carrying capacity allocation is not Uniform, and now the cable customers to take into account the economy and power grid design, cable model specifications will not leave too much capacity of the remaining capacity, when the line nose contact resistance is too large, one is the continuous use of the fever burned Off, and that is caused by two cable carrying capacity shift, resulting in one of the cable overheating burned 5 Multi-core armored power cable in parallel use in the AC power grid, each cable must be A phase, B phase, C phase alone out, respectively, with the switch A, B, C three-phase, Connect all the cores of a cable to a phase of the switch
