Adjacent to the secondary system of distribution transformer primary receiving different primary distribution main

This network is composed of multiple primary distribution mains supply through distribution transformers (also known as network transformers) Buck, after secondary distribution voltage fuses and connected to the grid . Adjacent to the secondary system of distribution transformer primary receiving different primary distribution lines, avoid the result of a distribution line Voltage stabilizer area blackouts.
Distribution lines and distribution lines by the structure with overhead lines and underground cables. China's existing urban and rural power distribution systems are mostly overhead structure, using reinforced mcb circuit breaker disabilities or steel rods and aluminum wire aluminum conductors; New tourist cities and metropolitan center, the new residential area is extensive use of underground cables. Urban low-voltage electric meter network, overhead lines and street trees caused power outages due to touch, electric shock accidents have occurred, this can be changed to low voltage overhead bare conductors insulated overhead cables or overhead lines.
