Q:The beginning of the 2007 are all very good, do not know what to do to open all the drawings are no bridge frame, and this CAD reloading a lot of back, what ah, and later installed 2010 open or not · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · More

(RJ45) when the crystal leader do not make 568A / B, or you do inside the leader is half of the inside, but also easy to happen to the landlord, The switch port is burned out and the correct wiring sequence is 12.34.56.78. A (RJ45) crystal head is 4 extensions. The outside line is the same connection, as you play patch panels in the order, is very good according to your line order to set, for example, 1. orange / orange 2. Basket / basket white 3. Green / green and white 4. Brown / brown white in the patch panel above is in accordance with the line you do this line to line it. This is the connection line of the telephone patch panel! But I was directly made of RJ11 crystal head!

Q:What is the number of the illuminated busway in the quota?

Control cables are generally AC / DC 220V or 110V, and a rated voltage does not matter.

Q:A. Fine coaxial cable B. Unshielded twisted pair C. Multimode fiber D. Microwave antenna more

audio and video cable disconnected or plug is not plugged in, the wrong hole

Q:Who can tell me that the electrical design inside the weak design is how to calculate the weak bridge to it, how to accurately calculate how much capacity should be used in the weak bridge, thank you more

National standard wire and cable requirements: the minimum value of the minimum value of the maximum diameter ~ the largest number of core countries have a national model models can also be customized according to customer requirements of different core number of different specifications of the cable other provisions: such as tensile pressure test Coal mine cable national standard is: MT818-2009 power cable is: GB / T-2008 Overall, each cable has its fixed standard, after the specific problem specific analysis of it pure hand, hope to adopt

Q:(4-20MA signal line, RS485 communication line, there are a few 220v power cord) can not be placed in the electrical cable trench, the design specifications are not required to add the problem: electricity is mainly 380V motor cable more many

Safe maximum capacity of 10A conversion success rate of 2200W assured use, there will be no problem.

Q:Who knows home improvement trough is generally playing high ah?

The powder coating will be uniformly adsorbed on the surface of the cable bridge to form a powdery coating. The powder coating layer is flattened and solidified by high temperature baking, and the powder coating is applied to the surface of the cable. Into a final coating with different effects (different effects of powder coating). Spraying effect in the 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.

Q:I would like to ask where the production of this aluminum alloy trunking Thank you Where is the production?

25cm weak bridge mount the top, the lighting cable bridge under the structure

Q:Please the architect of the structure of the experts to answer because the beginning did not understand, in the load bearing pillars opened a slotted board, and later said that this affected the structure of security, I would like to ask you how to help remove the experts to remove the plaster, No, how to operate well. More

Can be buried, it is best to use pest control, armored cable and plus casing

Q:There are several ways of wiring, there are walking bridge, take the metal trunking, and see there is a ground trunking, do not know how much this method used? Because the general look at the drawings, most of the shaft wiring bridge, indoor wiring to take the roof metal trunking. The The Have you ever seen a ground trunking? What are the aspects of the ground trunking? what is the benefit? In addition, how even always feel the wiring to take the ground trunking unsafe, because a lot of people walking around in the above. The The Thank you! More

There are some factories that are wiring the ground trunking. Here we are like this, there are many machines together, the cable through the ground trunking to the machine power supply.

Q:The contents of the VAT invoice for the other party: Ming bit alignment system materials, a group. And my unit is the entry slot, switches, etc., how should the invoice should be opened "

. the wire is the conduction current of the wire. . the cable is used to transmit (magnetic) energy, information and the realization of electromagnetic energy conversion wire products. . the wire is made of one or several soft wires, the outer package to soft and soft layer; cable is composed of one or several insulated package wire, outside the package to the metal or rubber made of tough outer layer. Cables and wires are generally made up of three parts: the core wire, the insulating sheath, and the protective sheath.
