1. The distance between the cable and the heat pipe should be 2m when installed in parallel, and 0.5m when crossing.
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).
6ã€6kV and above cable joints aã€When installing the cable terminal, the semi-conductive shielding layer must be stripped off, and the insulation must not be damaged during operation. The condition of knife marks and unevenness should be avoided. If necessary, sandpaper should be used to flatten the shield; It should be flat and the graphite layer (carbon particles) should be removed.
b. The copper shield and steel pick at the end of plastic insulated cable must be well grounded. This principle should also be followed for the short circuit to avoid induction dynamics at the end of the steel crucible when the three-phase unbalanced operation is running, and even “fire†and burning protection. Sets and other accidents. The grounding lead wire should be tinned and galvanized with tinned copper and copper cable, and should not be sealed with a torch to avoid burning insulation.
c. The three-phase copper shields shall be connected to the ground wire respectively. Note that the shield grounding wire and the steel wire grounding wire shall be led out and insulated from each other. The position of the welding ground wire shall be as low as possible.
8, the basic requirements of the cable terminal and intermediate joints: a. good conductor connection; b insulation is reliable, recommended radiation cross-linked heat-shrinkable silicone rubber insulation material; c. sealed well; d. sufficient mechanical strength, Can adapt to various operating conditions.
7. The end of the cable must be waterproof, as well as the erosion of other corrosive materials to prevent breakdown caused by aging of the insulating layer caused by water trees.
9. Cranes and forklifts must be used for loading and unloading cables. It is forbidden to lay them flat and lay flat. Large cable installations must be used to prevent cable from being damaged by external forces or scratching the jacket and insulation layer due to manual dragging. The cable is not installed, it is strictly forbidden to use human hand to make the conductor bent to damage the insulation layer and produce a short circuit.
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.
Note: The installation of wires and cables should be performed by an installer or a professional technician who is familiar with the performance of wires and cables. If there are still unclear matters, please consult the relevant technical department or the technical department of our company in time.
The present invention provides a multifunctional pull faucet, comprising: a faucet body, a drawing part is provided at the water outlet port thereof, and the drawing part is connected to a main channel, wherein at least three are provided in the faucet body A branch channel, and the three branch channels are all connected to the main channel. A multifunctional pull faucet provided by the present invention, wherein the hot water channel, the cold water channel and the water purification channel (pure water channel) are all connected to the main channel , And the main channel is connected with the drawing part on the main body of the faucet, so that the drawing part can obtain the water quality (hot water, cold water, purified water or pure water) required by different users, thereby improving the user experience, and , By integrating the hot water channel, cold water channel and pure water channel (pure water channel) into the main channel, the internal structure of the faucet is simplified, and the production cost of the faucet is reduced.
