Single-Pole Disconnector Switch
Type IA80 for medium voltage up to 36 kV and rated Current up to 630 A

The Disconnectors are single-phase double-blade disconnectors and vertical opening types by means of a hook stick pole, for vertical or suspended installation. These are manufactured according to CEI 62271-1 standard.
There are two versions: porcelain insulators with external metal fittings or polymer insulators.
There are two versions: porcelain insulators with external metal fittings or polymer insulators.
Sturdy design and hot-dip galvanized steel chassis
Economic cost compared to more advanced technology solutions
Use of quality galvanized parts and bearings for longer life
Disconnecting is actually visible to the operator, which provides great security
Manual operating mechanism with a head driver, and different accessories for different types of assembly, in substation and distribution lines
Coated copper contacts and blades “nickguard” that improve the electrical characteristics and allow better performance in high pollution environments
