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.

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: 3 by 16 cable is a few flat? How? That 5 by 16?: 1 Definitions and basic tasks Communication lines and ancillary facilities Routine inspection operations are based on regional characteristics of regular light cable line inspection and protection line publicity, timely detection of problems, troubleshooting factors to ensure smooth communication; communication lines and ancillary equipment to make up Strong, to ensure that the optical cable lines and ancillary equipment integrity is good to prevent the occurrence of failure

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: 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!: In accordance with the relevant safety regulations, the power cable should not be parallel to the top of the thermal pipe laying, when can not be avoided, the interval distance should not be less than 1000mm, during which should also take effective insulation measures. Power cable and thermal pipe cross, the thermal pipe insulation layer, the separation distance should be not less than 500mm, no insulation layer should not be less than 1000mm, and in the cross with the insulation board to be protected, the length of the insulation board should not be less than d + 2000mm (d for the thermal pipe insulation layer diameter).

Q: 5 air conditioning can be used 4 square cable: Lengthened low voltage side, the line resistance increases, the voltage drop increases. Reduced load capacity. So that the router due to insufficient supply voltage and can not work properly. It is not allowed to use 9V power supply. Voltage is too high, the router part of the internal power supply increased power, heat increased, it is possible to burn the router. It is necessary to extend the power cord, I suggest you extend the power supply side (220V one end) safe and reliable. Increase the voltage to increase the supply current, in the electrical working voltage range (with the electrical work voltage range) is allowed, too low electrical appliances can not work properly. Too high there is the risk of burning appliances, according to your actual situation, marked 5V0.2A that the router works at rated voltage, so the way to improve the supply voltage is not applicable. So you can only improve the power supply power (that is, you say to increase the power supply current rather than voltage). With the reserve power, it will provide enough current at the rated voltage (the router as a resistor, from I = U / R, you can know the danger of increasing the voltage) need help please message

Q: The difference between nylon balls and geese and ducks: As long as the cable is thick enough, 20 meters of the basic loss can be ignored.

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: 6 square cable up to how many air conditioning (1.5P): 7 kilowatts of electricity with what specifications of the wire if it is single-phase 220V, then 7 kilowatts of current is 7000 × 220V = 31.8A, check the electrical manual 4 square copper wire interception is 33A, to meet the requirements.

Q: 25 square copper cable how much money one meter?: 3 plus 1 64.13 yuan, 3 plus 2 75 yuan, 4 plus 1 81.38 yuan contact to see my registration name
