FAQ

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.
5 air conditioning can be used 4 square cable
Such as the extension line added to the adapter primary (city side) certainly easy to use. Extended by two meters, the router does not start, may be extended wire diameter is too thin, bold wire try. If not, choose 6V2A adapter try, the voltage is too high will burn the router. Increase the current is no problem, just like the computer's power, 300-watt power can be replaced, and small is not OK.
Can the main cable be aluminum cable? And explain why, thank you!
Excretion training is the use of positive reinforcement, that is, a variety of food, toys, the best time to reward
The difference between nylon balls and geese and ducks
If the 2.5 square copper wire for the output extension cable, 20 meters distance, the total resistance of about 2 * 1.7 * 0.2 / 2.5 = 0.272 (ohms), the current maximum 1.8A, the voltage drop is 0.272 * 1.8 = ), The charging voltage is 55-0.5 = 54.5 (volts), a difference of about 1% will not have any impact on the battery. However, the third floor, said Ye Hao, you can put the charger put the debris room, from your house put a 220V power cord down, home and then engage in a switch control. It is best to design a light at home, can intuitively see if the electricity is full. That's better. Design light, teach you a way: to find a bad leakless protector, open there is a coil-like ring-shaped stuff, called zero sequence current transformer, it will be down, be careful, do not put Transformers inside the coil hurt, get down, in the transformer two thin lines connected to a light-emitting diode. And then your 220V power cord line of fire from the center of the sensor through, around 3-5 turns. In this way, as long as there is current flow, the light-emitting diode will be bright, when the charge is over, the charging current is close to zero, the light-emitting diode will be extinguished. You can from the light-emitting diode is lit to determine whether the electric has been filled. I also have an electric bike that is so charged.
1000 kW 600 m cable to use much
Three-phase 380V, 1000 kilowatts load, the working current is about: 1899A. The total area of copper cable is not less than: 1200 mm2 copper cable. . the cable is usually a few or several groups of wires (at least two each) twisted from the rope-like cable, each group of wires are insulated from each other, and often around a center twisted, the entire outer package Highly insulated cover. Cable with internal power, external insulation characteristics. . the cable has power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire cables, marine cables, mining cables, aluminum cables and so on. They are composed of single or multi-strand wire and insulation layer, used to connect the circuit, electrical appliances and so on.
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!
heat shrinkable casing (MRSG) is a new environmentally friendly halogen-free flame retardant casing, inexpensive products, for wire, cable and wire terminals to provide insulation protection
How much of the cable with the switch?
The switch is selected according to the current. General switch = (2-2.5) Current three-phase current = P / 1.732 / 0.38 / 0.8 Single-phase current = P / 0.22 / 0.8
