High-voltage disconnectors 72,5-550 kV
Depending on type and voltage level, high-voltage disconnectors are manufactured as single-pole or three-pole gang operated units. The base of disconnector is made of steel profiles with high-quality anticorrosive protection. Robust current path is made of Al-alloy tube with contact system made from silver-plated copper.
Either one or two earthing blades can be attached to each pole of disconnector. Motor or manual drives with padlocking possibility in both operating positions are available for operation of main blades and earthing blades.
Disconnectors are delivered in assemblies and installation at site is easy with only simple adjustment. Parts of simple design and high-quality materials ensure high operational reliability with minimum maintenance required.
