Dedicated line is the dedicated line of electricity users. Is the user's own property rights, their own maintenance, while power supply has a high reliability. Non-green is relatively speaking, is hanging in a lot of users are using a bus on the same time. Non-green line is not caused by the substation, from the nearest capacity to meet the needs of the 10KV line attracted.
The distinction between special and non-specific depends on the nature of the load. Green line from the substation dedicated to the user, only for the user, do not accept the public network overhaul maintenance and power outages, also said that as long as the nearest substation power you have electricity; non-green as the public line. But now power supply reliability is so high, the city network are using ring network, the probability of power failure is small, not to mention you are using a dual power line, power failure is smaller, unless the area power outage. But you also have an important load on their own generators, so non-particularly important load, double power enough to meet its power supply needs.
