Abstract
A supporting insulator for installation between connecting flanges of a gas-insulated switching installation is provided with an outer ring, with an insulator body which is in the form of a disk and which is formed of a hardened cast resin, and with at least one cast fitting which is subjected to high voltage and is cast in the insulator body. The outer ring need not be assembled with the insulator body until after the outer ring has been colored. The outer ring includes two identically constructed rings that are joined together in a separable, but positively locking manner such that the insulator body can be separated from the outer ring when the rings are separated.
