��Ʒ���ƣ�Eaton 12kV ET1 Medium-Voltage Switchgear
Product Overview
12kV ET1 is the indoor metal-clad air insulated medium voltage switchgear. Benefit from
Eaton��s the new vacuum technology and the mature epoxy-resin insulation technology, it is approved comprehensively through type testing and qualification. The product is mainly applied in the power plants, transformer stations, mining enterprises and high-rise buildings with optimized safety, reliability, cost-effectiveness, and high performance. The 550mm width compact solution better suits the application in projects with restricted spaces such as the commercial real estate, data centers and retrofit.
ET1-12 switchgear comprises a complete range from 1250A up to 4000 A current.
The main busbar current can reach 4000A. Adopting the vacuum interrupting technology and the composite insulation technology, the switchgear is the best of its kind in the medium voltage field to replace the environmentally harmful SF6 gas insulation equipment.
It is also produced with fully recyclable materials ensuring that at the end of its life theproduct can be safely and efficiently recycled �C providing a wholly sustainable solution to medium voltage switchgea applications.
