2. When the cable is installed parallel or crosswise to other pipes, it must maintain a distance of 0.5m.
3. When the cable is directly buried and installed, the depth of direct burial of the 1-35kV cable shall not be less than 0.7m.
4. The mutual installation distance of 10kV and below cable shall be not less than 0.1m, 10-35kV shall not be less than 0.25m, and the distance shall not be less than 0.5m.
5, the minimum bending radius of the cable, multi-core cable shall not be less than 15D, single core cable shall not be less than 20D (D is the cable outer diameter).
6, 6kv and above cable connectors.
A. When installing the cable terminal, the semi-conducting shield must be stripped, and the insulation must not be damaged during operation. Knife marks and irregularities should be avoided. If necessary, sandpaper should be used to grind; the shield end should be flat and the graphite should be put. The layer (carbon particles) is cleared.
B. The end of the plastic insulated cable copper shield and steel pick must be well grounded, this principle should also be followed for short lines, to avoid induced electromotive force at the end of the steel crucible when the three-phase unbalanced operation, even "fire" and burning jacket Other accidents. The grounding lead wire should be tinned and woven copper wire, and the soldering iron soldering should be used when connecting with the copper tape of the cable. It is not suitable to use the torch light seal welding to avoid burning insulation.
C. The three-phase copper shield should be connected with the ground wire separately. Note that the shield grounding wire and the steel wire grounding wire should be led out and insulated from each other. The position of the welding ground wire should be as low as possible.
7, the basic requirements of the cable terminal and intermediate joints: a. good conductor connection; b. reliable insulation, recommended radiation cross-linked heat-shrinkable silicone rubber insulation material; c. sealed well; d. sufficient mechanical strength, Can adapt to various operating conditions.
8. The end of the cable must be waterproof and corroded by other corrosive materials to prevent breakdown due to aging of the insulating layer caused by water trees.
9. The cable must be loaded and unloaded by cranes or forklifts. It is forbidden to lay flat and lay flat. When installing large cables, the cable car must be used to prevent the cable from being damaged by external forces or scratching the insulation due to manual dragging.
10. If the cable cannot be laid in time for any reason, it should be stored in a dry place to prevent sunlight exposure and water ingress at the end of the cable.
