2 Using features:

 

1. Rated voltage: Uo/U:3.6/6kV, 6/10kV(11kV), 12/20kV(24kV), 19/33kV, 26/35kV(35kV).

2. No. of core: Single core or three cores.

3. The highest allowed operating temperature of conductor for long-term working is 90oC. In short-circuit (Max. long-term is no more than 5 seconds). The highest temperature for conductor is no more than 250℃.

4. D.C. resistance of the conductor complies with the stipulations of 3.6/6kV, 6/10kV(11kV), 12/20kV(24kV), 19/33kV, 26/35kV(35kV).

5. The environment temperature should be no lower than 0oC when lay. Otherwise it should be preheated.

6. The cable is laid without horizontal drop limit.

7. Working Frequency Voltage Test: 3.5Uo/5min without puncture.

8. Partial Discharge Test: The discharge volume should be no more than 10pC under 1.73Uo for the cable.

9. Minimum Bending Radius

Single core - Fixed: 15 x overall diameter

3 core - Fixed: 12 x overall diameter

(Single core 12 x overall diameter and 3 core 10 x overall diameter where bands are positioned adjacent to joint or terminations provided that the bending is carefully controlled by the use of a former)

Note:

The single core armoured cables are used for D.C. system only. If used for A.C. system, the magnetic isolation should be applied on the steel armoire wires of non-magnetical materials should be used.

Q:What is the position of the wire in the wall?
It shows that the design is unreasonable The correct approach is that there is a special cable wells in the best, however, the general construction unit is too expensive to save this may be bitter construction units continue to repair, it is difficult to cure here to introduce a few ways, According to the situation selected: . casing filled with dry cement, and with a wooden hammer tamping, but a certain idea of security, high pressure line once rammed the skin is too dangerous, should be done before power, you now estimated to have power, . outside the set of electric wells, the depth of the bottom of the casing in the 1 meter or so, and the wells do waterproof, wellhead should be hardened around, to avoid rain immersion, you seem to have done, but do not good enough, at the same time Into the built-in automatic suction pump, rain more than a certain depth of automatic drainage, is the price slightly higher; . in the cable casing surrounded by water swelling type of water, such as BW Zhishui, etc., but the effect in general.
Q:How can the most effortless way to put the cable on the bridge
Red line is the line of fire, green line is zero line, black line (should be gray) is to protect the zero line.
Q:Will the installation of the socket and switch what are the requirements? How should the wire tube be discharged?
In the choice of power lines, the equipment power must be known, with this known conditions, the use of three-phase AC power formula, the current, the formula: P (electric power) = √3 × 380 (three Voltage) × I (current) × cosφ, the formula cosφ for the inductive load reactive power loss, conservative some of the constant 0
Q:What are the electrical equipment? What are the main parts of each device?
Oh, the chassis of this thing or belong to the "heavy industry" products, thin when the evaluation of electronic industrial products standards, the chassis does not apply
Q:Please use the CPU power to extend the line of people come in! Thank you
YJV and VV are the main models of commonly used power cables. VV cable is: PVC insulated PVC sheathed power cable; YJV cable is: cross-linked polyethylene insulated PVC sheathed power cable. These two are currently used in industrial and mining enterprises and residential areas are more, but only in common occasions, due to the needs of the characteristics, so with the former suffix, in front of some plus NH or ZR, said the fire-resistant and flame-retardant, Plus P, that the shield type. VV22-4 * 25 + 16 Strictly speaking should be VV22-0.6 / 1-4 * 25 + 1 * . said PVC insulated PVC sheathed striped armored low voltage power cable, 22 said strip Armor, 0.6 / 1 that voltage level, 4 * 25 + 1 * 16 cable that a total of five core, of which four 25 square and a 16 square, which is used in the three-phase five-wire system, A, B, C, N is 25 square feet and the PE line is 16 square.
Q:0.5 square feet can bring the number of watts
Check the electrical manual: 0.5 square copper safety cutoff is 8A. 220V × 8A = 1760W.
Q:How is the color of the three wires?
Do not listen to upstairs nonsense, ask you how you use the carriage line?
Q:Is it necessary to protect the buried cable? What position is needed?
Do not specifically do maintenance, will be miserable, with the point of doing the hardware or software sales can also do things such as Internet cafes system maintenance and wiring and the like, start the fund is not very high, only the accessories as long as the common model accessories There are on the line, maintenance test tools also can not spend much money.
Q:6000 watts of electrical appliances to be large wire bearing
Single phase with 6 square 3 phase equipment with 2.5 or 4 square on OK OK!
Q:How to choose the size of the wire.
First, the single-phase 220V voltage, power 15.5KW with the rated current I = P / U = 15.5 * 1000/220 = 70.45A16 square copper and 25 square aluminum bearing current is 100A, and then smaller specifications of the wire Up to 70A, two, three-phase 380V voltage, power 15.5KW with electrical, rated current of about 31A. 6 square copper and 10 square aluminum wire carrying current of about 40A. If you intend to use a single attack long short of the short-Chi of the E-law, so you three-phase five-core line, copper wire is not less than 16 square feet, aluminum is not less than 25 square if you use 380V three-phase electricity, then You three-phase five-core line, copper wire is not less than 6 square, aluminum is not less than 10 square feet.
