Product Description

Solid Insulated Metal-Enclosed Sf6 Electrical Switchgear (SRM16-12)

.Overview

By the perfect integration of stationary type and flexible expansion, SRM16-12 type SF6 gas-insulating compact close metal switchgear with the adoption of the modular design,can be fixed of extended,it is suitable for end-user or network node, meanwhile meets the requirement of all kinds of switching substations cabinet-type transformer substations and cable
Branch cabinets. It characters on its compact structure, safety and reliability, longevity and maintenance free.

.Environmental conditions

1.Elevtitude of ≤ 3000 m

2.High ambient temperature + 55℃, lower temperature-45℃

3.High humidity and high average relative humidity

4.Measure 95% of ≤ for 24 hours, and 90% for 1 month

5.Seismic seismic intensity shall not exceed 8 degrees

6. No fire, explosion hazard, serious filthy, chemical corrosion, as well as places of intense vibration
