Here's a scarce ribbed disc insulator from Spain used to support wall bushings or cables through walls in substations and indoor powerhouse. Most likely an unembossed Esperanza SA product. The ribs increase the leakage distance and strengthen the weight capacity of the insulator. Measures 8 1/2 inches across. Outer ring is also unusual in that it is not flush but instead has a 3/4 inch extension. This has similar dimensions to the Italian CD 1171 except that is has 5 ribs whereas the Italian only has 4. For a better detailed view of an identical disc [id=429998484].

Has some light nicks and teeny flakes and some light scratch marks. Lots of factory surface straw lines. VNM condition. First email gets this rarely offered disc insulator for the reduced price of only $85 plus shipping. Thanks!
