Description:
EMT steel couplings are used to connect the ends of two unthreaded EMT conduits together. EMT steel set-screw couplings provide concrete tight connections when taped. Additionally, these set-screw couplings eliminate the need to thread bald conduits to fit old threaded couplings. EMT steel couplings are steel and with zinc-plate surface for excellent corrosion protection in damp location.

Q:How much of the cable with the switch?: Switch = (2-2.5) current three-phase current = P / 1.732 / 0.38 / 0.8 single-phase current = P / 0.22 / 0.8

Q:What is the meaning of PG + digital markings for electrical wiring?: The best cement and other dry in the closing, because the wet cement contains moisture, can be conductive, dry the probability of conduction less. Pay attention to the wire to maintain integrity, no broken skin, it is best to protect the casing.

Q:25 square copper cable how much money one meter?: Copper should be more than 2.7 flat. Aluminum to 4.5 or more.

Q:Is the cable head made of every building?: Building in accordance with the floor or unit configuration distribution box, there are office buildings using a total box. Where there is a cable out of the situation, must be wrapped to make the cable head, according to the choice of distribution box circuit breaker wiring crimp or not crimp the cable terminal. In other words, the cable head must be made, but not necessarily crimp the cable terminal.

Q:6 square cable up to how many air conditioning (1.5P): If it is connected to the 220V of the electricity above the 6 square of the copper line can be

Q:Does anyone know the "line buckle" classification (including shape / size / material / has been some commonly used size!) Line deduction is a hardware products! For daily necessities!: If you want to ensure that the transmission medium does not cause the signal to cause attenuation and interference, fiber transmission or balanced cable transmission is the best solution. If you need fiber transmission, the cost is high because you need to buy digital fiber converters and digital audio decoders and related equipment, but this can be to the maximum extent to ensure the integrity of the signal and the smallest noise interference. If you want to use low-cost transmission can also be used directly to the cable transmission, but must use a balanced interface for transmission, and with 2-core shield or 3-core, 5-core shielded cable for transmission. This can also ensure the clarity of the signal to the maximum extent, but do not eat hungry thirsty 丨 Chicken check blood sausage is too long. No matter how good the cable will be attenuated, the size of the attenuation will directly affect the signal quality and signal integrity. So the transmission distance with the balance line can not be too far. More than two kinds of transmission methods than the existing single-line transmission is much better, if you are a fever-level players, I suggest you use fiber transmission. But if your power amplifier or your source signal to noise ratio is not high, I do not recommend you use fiber transmission, because even if the quality of fiber transmission no matter how good your source is not high, then it does not make sense The

Q:The difference between nylon balls and geese and ducks: It depends on the thickness of the wires you use. The thicker the copper wire is, the better. Because the distance will be a voltage drop. So be it, you use a multimeter to look at how long you charge when the output voltage is how much. If you can more than 50 should be no problem. If the voltage is relatively low can change a rough wire, or find a few wires in parallel can also be. I do not know if you can understand it. Even if there is a voltage drop if it is not very powerful should not be the problem, the worst result is the battery charge dissatisfaction. You can try to see how the effect of the day. Certainly will not break your equipment and battery, rest assured it

Q:Can the main cable be aluminum cable? And explain why, thank you!: Reply to the landlord: I read a part of the literature, more Google is aware of the following part may be your reference weak construction specifications 1

Q:How do I ask for cable prices? How many tons is one or more?: As long as the line connected to the corresponding location, that is, audio cable audio and video cable, video cable can be used with the video line.

Q:1000 kW 600 m cable to use much: Depends on the load is emotional, resistive, should be too long cable, consider the pressure drop. Generally consider 2.5 or more.
