1. Compact, modular design. Current level and voltage level covering wide. Volume was significantly reduced.
2. Fully respect the design concept of air insulation.
3. Circuit breaker can be easily removed replacement and maintenance.
4. A group of switchgear need to repair and replacement, which can be hanging out of any one side alone.
5. Can achieve automated assembly line production.
6. No exposed electrical conductors, more secure operation.
7. No need to draw out the circuit breaker; to complete the isolation switch and grounding switch remote operation, so that distribution network automation become a reality.
8. Environmental adaptability; installation of enclosures can improve the operating altitude of the site.
9. Production, use and exit the whole process of environmental protection.
