DISCONNECTOR AND A SUPPORT INSULATOR THEREFOR
First Claim
1. A disconnector for obtaining a physical interruption of a current path being at a high voltage of at least 100 kV with respect to earth, the current path comprising a plurality of conductors each on a high level above the ground, said disconnector comprisingtwo groups of a plurality of elongated post-like support insulators adapted to rest on a ground surface and support an end one of the plurality of conductors included in said current path, anda disconnector arm supported by at least a first of said support insulator groups, the disconnector arm being connected by one end thereof to an end of a first one of said conductors, each disconnector being moveable from a closed position in which the disconnector arm by a second free end thereof connects to an end of a second of the conductors for disconnecting said ends of said first conductor and said second conductor from each other, wherein at least external parts of said support insulators comprise a hydrophobic rubber composite insulating material.

Abstract
A disconnector for interrupting a current path on a voltage of at least 100 kV with respect to earth. Two groups of elongated post-like support insulators are adapted to rest on the ground and support an end of a conductor each on a high level above the ground. A disconnector arm is connected to one or both of the conductor ends and is moveable for connecting and disconnecting these conductor ends. At least the external parts of the support insulators are made of a hydrophobic rubber composite insulating material.
