Switch Disconnectors

The main goal of the development project for the new centre break disconnectors and earthing switches is to provide our customers more economical solutions. This is achieved both through a high level of standardisation of the design for the whole voltage range 72.5 – 170 kV and by featuring state-of-the-art manufacturing techniques for the individual parts. The open design of the bended current carrying arms ensures high heat dissipation while using reduced amount of aluminium. The contacts of the disconnector and earthing switches are maintenance free up to 10’000 operating cycles which contributes to decreased life cycle costs. Additionally, the new design allows easy assembly and adjustment of the switchgear
