Necessary "careful machine" for installing wires


1. Please check the insulation of the wire or the appearance of the jacket before use to prevent damage caused by improper transportation or storage and affecting the use effect.

2. The wires should be laid at room temperature not lower than 0 ° C. The bending radius should not be less than 6 times the outer diameter of the wires to prevent cracking.

3. The long-term allowable working temperature of the wire should not exceed 70 ° C, except for the special specifications of Zhengzhou wire and cable (fire-resistant or fire-resistant wire).

4. According to the size of the line transmission current and the ambient temperature during use, choose a suitable conductor cross section to ensure safety.

For example, indoor lighting cables (two-phase) can use BV1.5 square millimeters, and power outlets (less than 2000W loop, three-phase) can use BV2.5 square millimeters. One or less air conditioner circuits (three-phase) generally use 1.5 square millimeters, and larger power should use 2.5 square millimeters or even larger cross-section wires.

5. In order to ensure the safety level of the house, a multi-branch power distribution circuit design should be adopted.

6. When in use, the surface of the wire must not contact the heat source.

7. Know the knowledge of fire wire, ground wire and neutral wire, and choose the correct and proper color wires according to your needs. According to China's current standards, the third line in GB2681 to mark the circuit according to the color of the wire should generally be the phase line: yellow for phase A, green for phase B, red for phase C, light blue for neutral, and white for control line The ground wire is yellow-green (two-color).
