Aluminum Alloy Prefabricated Branch Cable

Description
Prefabricated cable is primarily applicable for power supply and distribution system in fields like metro, ring road, high-rise office building, residential building, hospital, shopping mall, factory power distribution, air port, bridge and tunnel construction field, etc.

Advantages
1. Prefabricated cable features good shock resistance, air tightness, water repellency and fire resistance.
2. Without connector, main cable conductor is characterized by good continuity and low stoppage rate.
3. Prefabricated branch cable (aluminum alloy) adopts complete mechanical pressure welding technology so as to avoid human’s interference.
4. Prefabricated cable is characterized by small branch contact resistance. It is not affected by thermal expansion.
5. Prefabricated branch cable can be customized. Branch location can be set according to the distribution points of power distribution system.
6. Prefabricated cable the feature of low distribution cost and construction cost, high economic indicators and significant efficiency.
7. Prefabricated branch cable (aluminum alloy) has the characteristics of convenient installation and short construction period.
8. After installation, this prefabricated cable needs no maintenance.
