telephone, single petticoat insulators were standard for toll line construction.
The Hemingray No. 16, with a single petticoat is still widely used for lines of
medium length."
"The No. 16 has about the longest leakage path possible for a single petticoat type on a standard pin. It has a square wire groove." "The No. 17 is exactly similar to the No. 16 except it has a somewhat wider groove for larger wire." |
