The P-94 disconnectors have been designed for overhead distribution networks up to a maximum voltage of 36kV. They allow isolating the network downstream from a permanent fault and ensure maintenance interventions in complete safety.

In this device, the classic pantograph of overhead switches has been replaced by a copper contact knife. Its “U” profile provides great elasticity, ensuring perfect electrical contact on both the fixed contact (break contacts) and the articulation side. The movement of the contact knife is ensured by the tilting of the mobile insulator.

There are two versions of this switch:

• The “P-94” with porcelain insulators.
• The “P-94P” with polymer insulators.

The steel screws and metallic parts are hot-dip galvanized.

There is also an option with epoxy and polyurethane protection and stainless-steel screws. The respective references are “P94sp” and “P-94Psp”.

This “sp” version ensures exceptional resistance in severe chemical pollution conditions and aggressive climatic environments (seaside, sandstorm, etc.).
