Product Description

Outdoor 27.5V Switchgear, Ring Main Unit Leading Manufacturer for Power Plant/ Transportation


Outdoor 27.5V Switchgear, Ring Main Unit Leading Manufacturer for Power Plant/ Transportation
Important Features
  • Product, supportor and other exposed metals adopt hot galvanizing and epoxy powder coating treatment for outdoor use. The product has superior anti-corrosion and can be used for a long time at outside.
  • Cylindrical poles of CB adopt design of solid insulation. After cleaning and dryness, vacuum interrupters should be poured into silicone rubber as a buffer layer, and then solidified with epoxy resin through pressure, and finally poured with hydrophobic silicone rubber with umbrella skirt from outside. This design can make that cylindrical poles have excellent ability to withstand short-circuit and strong bending resistance.
  • Creepage distance of cylindrical poles: 1450mm (to earth), 1650mm (between the top terminal and bottom terminal), have strong ability to resist dirtiness.
  • The circuit breaker uses long-run validation operation mechanism with frequent operation, and electrical life is more than 20000 times.
  • Breaking capacity of circuit breaker is strong, short-circuit breaking current is 31.5A (30 times).
  • Insulation degree is high, and the product can adapt to 3000 meters above sea level.
