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

- Q: 1000 kW 600 m cable to use much
- Such a large load so far away, can only be transported with 10KY, near the installation of the transformer Caixing, if the 380V transmission, cross-sectional area, high cost, loss of large, not worthwhile. 10KV high-pressure delivery, current 55A, with 25mm? copper cable 35mm? aluminum cable delivery on it. If the 380V transmission, according to the line voltage loss simple calculation formula △ U% = PL / CS take △ U% = 5 copper cable S = PL / CS △ U% = 1000X600 / 77X5 = / 385 = 1558mm? aluminum cable S = PL / CS = U06 / 46X5 = / 230 = 2307mm? Line voltage loss △ U Simple calculation formula △ U% = PL / CS △ U% - Percentage of voltage loss P - Active power of conveying (Kw) Distance of L- M) C-constant, aluminum single-phase 8.. aluminum three-phase four-wire 46; copper single-phase 12.. copper three-phase four-wire 77S-conductor cross section (mm?) (quoted from "electrical entrance permit test low pressure Class theory "" electrical engineering basis ")
- 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: 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: 3 by 16 cable is a few flat? How? That 5 by 16?
- Is the power directly out of the CPU power supply line or on this basis and added the extension line
- 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!
- 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
- Q: 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.
- 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)
- If it is connected to the 220V of the electricity above the 6 square of the copper line can be
- Q: 25 square copper cable how much money one meter?
- There is no 1..2..4.5 square wire. The family uses most of the four wires with 1.. 1.. 2.5 and 4. Power 1KW Approx. 5A.3KW Approx. 15A.2.5 square copper wire can be used. Plug or empty open (25A).
