Description:
EMT couplings are used in dry location to connect the ends of two unthreaded EMT conduits together. EMT aluminum 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 conduit couplings are pure aluminum material for excellent corrosion protection in damp location.

EMT Coupling
American Standard
UL Standard 514B
Size: Zinc 1/2" to 4"
Aluminum 1/2" to 2"
Set-screw type
Material: Zinc/Aluminum Die Cast

Applications:

These set-screw couplings are used in dry locations to connect the ends of two EMT thinwall conduits together. topele’ die-cast aluminum, set-screw couplings provide concrete-tight connections when taped and properly secured with the included set-screw. Topele’ set-screw electrical couplings are rated for electrical applications above 600 volts.

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?: First, the cable production and installation of each building has. Second, the cable terminal set of waterproof, stress control, shielding, insulation in one, with good electrical and mechanical properties, in a variety of harsh environmental conditions for long-term use. With the advantages of light weight, easy installation and so on. Cable terminal is widely used in electric power, petrochemical, metallurgy, railway ports and construction and other fields. Third, the production process: including the following: . cut off the excess cable; . the cable protective layer of the stripping; . conductor connection; . wrapped around insulation (or shrink pipe); . install the connector shell; . ; . for sealing treatment.

Q: What is the meaning of PG + digital markings for electrical wiring?: If no color distinction, 100 meters after you know which line of the fire line which line? The

Q: 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

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: 5 air conditioning can be used 4 square cable: You do not use the 9V power supply, a long time will burn the router.You'd better measure the original adapter voltage, if you want to extend the power cord, it is best to use a thick line of reliable connection, you can not start now, you can not start Depending on whether the extension line is too thin, causing the voltage drop too much.It is necessary to extend the front end of the adapter can extend the 220V power cord.

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?: Yellow line is video, red and white are audio, you can only pick one!

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
