Distribution Accessories Factory introduces the basic requirements for selecting cables:

1. In general environments, aluminum-core cables should be used. In places with severe vibration and special requirements, copper-core cables should be used; large-scale important public buildings should use copper-core cables.

2. For buried cables, armored cables with outer sheaths should be used; in places where there is no possibility of mechanical damage, plastic-sheathed cables or lead-clad cables with outer sheaths can also be used;

3. In soils where displacement may occur (such as swamps, quicksand, near large buildings), steel wire armored cables should be used for buried laying, and measures can also be taken to eliminate the stress on the cables due to cable displacement, such as reserved Cable length, soil reinforcement with sheet piles or row piles, etc.

4. In soil with chemical corrosion or stray current corrosion, it is not suitable to lay the cable underground. If it must be buried, the anti-corrosion cable should be used or measures to prevent the stray current from corroding the cable should be adopted.

5. Cables laid in pipes or pipes should be plastic sheathed cables or bare armored cables.

6. When laying cables in cable trenches or cable tunnels, there should be no flammable and flammable outer sheaths. Bare armored cables, bare lead cables, or flame-retardant plastic sheathed cables should be used.

7. Overhead laying should use cables with an outer sheath or all-plastic power.

8. When the cables are laid in places with a large height difference, plastic insulated cables, non-drip cables, or dry insulated cables should be used.

9. In the three-phase four-wire system, four-core cables should be used.

10. Fire-resistant cables can be used for important backup trunk lines (such as the connection line between the backup generator set and the transformer).

Through the above introduction, Coaxial Cable Manufacturers hopes that you can simply refer to the content of this article in future use.
