Cable threading through conduit with wire glands
Thread Content
How should elbow wire glands and straight wire glands be configured when running cables through ducts?
The specifications state that a wire gland must be installed when the total bending angle of a single pipe is greater than 270° or its length exceeds 30 meters. The wire gland can be connected to the protective tube by threading
It is best to use conduit boxes at all corners for connection, which facilitates construction, improves aesthetics, and makes it easier to run cables.
Currently, the wire ducts used are generally of DN15 or 20 size, with a standard length of 6 meters per unit. On-site, straight wire duct boxes and bent wire duct boxes are usually used together; at the corners where the wire ducts need to turn, the construction team simply bends the ducts themselves!
