Traction Air Insulated DC Switchgears
Traction Air Insulated DC Switchgears
TAIS 0.6-3.3 kV IS&T series
TAIS DC IS&T air insulated switchgear is:
- A prefabricated metal structure consisting of a galvanized steel body with metal partitions between compartments;
- Indoor installation;
- Single-sided maintenance (two-sided upon request);
- With fast 1-pole DC air circuit breakers;
- With DC current 1-pole/2-poles disconnectors.
TAIS DC IS&T replaces the following well-known analogs:
