When installing cables, the pulling force mainly refers to the traction force. There is a calculation formula for this type of pulling force, which varies depending on the laying type. Generally, it is divided into horizontal straight traction, inclined straight traction, horizontal curved traction, vertical curved traction, and vertical traction on an inclined surface. You can refer to the detailed calculation formulas in Volume 3 of the Wire and Cable Handbook.
What is the method for installing household electrical wires?
1. Generally, the wire used for sockets is a single-core wire of 2.5 square millimeters. For air conditioners above 3 horsepower, a single-core wire of 4 square millimeters is used, and a single-core wire of 6 square millimeters is used for the main incoming line. Two-color wires are used for grounding.
2. Three rolls of different colors are grouped together (for neutral wire, live wire, and ground wire). The wire used for lighting fixtures is a single-core wire of 1.5 square millimeters, while two rolls of different colors are grouped together (for neutral wire and live wire).
3. Two-core and three-core sheathed wires are used for exposed wiring and are mostly used on construction sites; they are not commonly used in home decoration.
4. The thicker the audio cable, the better; it is recommended to choose specifications of 2*1.5 or 2*1.2. 5. The more outputs a TV splitter has, the worse the TV signal becomes; it is recommended to use splitters with no more than 6 outputs.
