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:What are the electrical equipment? What are the main parts of each device?
Under normal circumstances, the weakness of the bridge with more, like office buildings are generally in the corridor, if the strong power from the corridor to take the cable or wiring more, are not easy to embed, you can also walk the bridge, as to why the use of bridge , Because the wiring into the inside, and finally wrapped with iron, the equivalent of a channel to protect the isolation, no special meaning
Q:High-voltage cable can not be weak and cloth in the same cable trench
The door there is a pole, if it is facing, there will be bad results, of course, this depends on how you look at the direction of the door, with the day after tomorrow, the corresponding correspondence of the gossip, to know what the family What happened. Resolve the way, with a concave gossip ytterbium is facing the poles can be
Q:Can cable tube and gas pipe hot water pipe be laid at the same time?
laying in the metal trunking is only the cable itself (not through the tube)
Q:Brick and concrete structure of the wall and roof how to embed wire tube? The
If there is no wall, you can in the wall when the embedded tube, if it is already a good wall, it is necessary in the wall slotted wiring, how to do depends on your wall status.
Q:Will the leaking water cause a short wire in the wall?
Can not find the system files, will be installed at the end of the first test, the hard disk problems will be prompted;
Q:Electrical Resistance in Wires?
Cost and space.thicker wires cost more and they would be too heavy for pylons. Silver has a lower resistance than copper but it's not used because it's too dear.
Q:1 square wire can load how much power
You remember, a square of the copper core line can not allow more than 8A of the current through it, under normal circumstances, we take 5 to 6 years of current to count, remember too much, and trouble, only Disrupting our memory. This value is applicable in low voltage
Q:Electrical wiring circuitry?
Don't know where you live (country) but in N.A. the white will be common and the tan(sometimes red) and black are power the white will go to both the light and the receptacle-whatever color (tan or black) is in the receptacle will be constant power-and the other should come from the switch to the light
Q:I'm wiring the electrical on a new dishwasher,?
Use wire nuts, NOT JUST TAPE. Invest in an inexpensive tester to determine which one is the hot lead - that connects to the black wire. To be safe, why not call a local handyman who has done this before if you are unsure? Water and electricity don't mix, especially if you miss grounding the unit or incorrectly switching the hot and neutral.
Q:What is the position of the wire in the wall?
With linseed stuffing, and then no words with rubber stopper, but must be on the outside Caixing.
