Cable operation conditions

1. Laying in air

1.1 when the single core cable is laid in parallel, the center distance: 185 mm 2 or less is twice of the cable diameter, and 240mm 2 or more is 90mm.
1.2 ambient air temperature: 40 ℃
1.3 long term maximum operating temperature of Conductor: 90 ℃

2. Directly buried laying

2.1 When the single core cable is laid without contact, the distance between the center of the cable is twice the diameter of the cable.
2.2 soil temperature: 25 ℃
2.3 long term maximum working temperature of Conductor: 90 ℃
2.4 soil temperature coefficient: 1.0 ℃. M / W
2.5 direct burial depth: 0.7m

Cable installation and use

1. Cable selection

1.1 the rated voltage U0 / u (UM) of the cable is shown as: uo is the rated power frequency voltage between the conductor for the cable design and the ground or metal shield, u is the rated power frequency voltage between the conductors for the cable design, and um is the maximum value of the highest system voltage that the equipment can withstand.
1.2 according to the different laying environment and load of the cable, correctly design and select the type and specification of the cable. Non armored type is suitable for overhead, indoor, tunnel, cable trench and other occasions, and can not bear external mechanical force; The armored type can be directly buried underground under the same conditions as the non armored type, and can bear certain external mechanical force. Single core cable is not allowed to be laid in magnetic pipe. Special type of cable should be selected for inflammable and explosive, chemical corrosive, high temperature and low temperature.

2. Storage and transportation

During the storage of cables, the packaging shall be standardized to avoid long-term outdoor sun exposure, both ends shall be reliably sealed, long-term storage and humid environment are not allowed, and the cable reel cannot be placed horizontally. During transportation, the height of the plate should be considered and fixed effectively. During hoisting, several plates are not allowed to be hoisted at the same time, and it is strictly forbidden to push down from a high place.

3. Laying and installation

3.1 special tools such as pay off rack and guide roller shall be used for cable laying to prevent mechanical damage and keep away from heat source.
3.2 when the cable is laid through the pipe, the inner diameter of the pipe shall not be less than 1.5 times of the outer diameter of the cable. When multiple cables are laid through the pipe, it is forbidden to twist and squeeze the cable. The pipe has enough capacity, and the total area of the cable shall not exceed 40% of the total area in the pipe
3.3 the minimum temperature of cable laying shall not be lower than 0 ℃, and the bending radius shall not be less than 20 times.
3.4 when the traction conductor clamp is used for laying, the maximum allowable traction force is p = OA (n), a conductor section. O is 50N / mm2 (copper) and 30n / mm2 (aluminum).

4. Test

After installation, the insulation resistance of the cable shall be tested without load. If necessary, AC power frequency withstand voltage test shall be conducted for 1min
