Second, wire and cable common sense
1, what is a cable intermediate joint?
Answer: The device that connects the conductor, insulation shield and protective layer of the cable to connect the cable is called the cable intermediate joint.
2. What are the main electrical circuits?
Answer: Electrical main wiring is the connection mode of electrical main equipment and bus in power plants and substations, including the connection mode of main bus and auxiliary power system according to certain functional requirements.
3. What regulations should be followed when selecting the section of power cable?
Answer: The selection of power cables should follow the following principles:
(1) The rated voltage of the cable shall be greater than or equal to the rated voltage of the power supply system at the installation point;
(2) The continuous allowable current of the cable shall be equal to or greater than the maximum continuous current of the power supply load;
(3) The cross section of the wire core should meet the requirements of the stability of the power supply system in case of short circuit;
(4) Check whether the pressure drop meets the requirements according to the cable length;
(5) The minimum short-circuit current at the end of the line should enable the protection device to operate reliably.
4. What are the advantages of 4.XLPE cable compared with oil-paper cable?
Answer: (1) is easy to install, because it allows a small minimum bending radius and light weight;
(2) wireless drop *;
(3) Good thermal performance, high allowable working temperature and large conveying capacity;
