The insulator factory and ovens were located on the SW corner of Velma Grove and Mount Dandenong Road approx. Quarrying for clay was done in the nearby area. Refer photographs of the factory.Two ceramic insulators made in East Ringwood from local clay. Colour grey. Conical with indentation in middle for wires. There is a second 'skirt' inside to enhance insulating performance. The inner hole is threaded.

This insulator was used on phone wires. Insulators were originally designed to keep the wires linking telegraphs and telephones insulated from the wooden poles that held them aloft. Prior to 1925, Australia relied solely on insulators imported from other countries. Glass insulators were first manufactured in Australia in c. 1926 by Australian Glass Manufacturers. Their factory was, and still is, located on South Dowling Road in Sydney. Australian Glass Manufacturers (A.G.M.) had developed a toughened type of glass very similar to Pyrex glass. Since the Pyrex name could not be used due to trademark infringements, they called their glass AGEE for Australian Glass. Many fruit jars, insulators, pie dishes and other glass items were manufactured with this AGEE trademark during the 1926 to 1940 period.Glass insulators are rapidly becoming a thing of the past in Australia with open-wire communication lines rarely existing near metropolitan areas. The remaining open wire lines are being abandoned and dismantled everywhere with very few insulators being saved as interest in them in Australia is quite limited.

Modern communication tecnology arrived on Gabo Island with the construction of the telegraph line from Eden to Gabo Island in 1870. These and other cylindricial insulators were associated with the original 1870 copper wire telegraph line and later the P.M.G. line. The items of telegraphic equipment comprise a number of ceramic and glass insulators of varying age and type. Two bell-shaped insulators are made of clear glass, one with remains of wooden dowel inside. In addition to insulators, there is a telephone insulator bracket made of metal with wooden pins. It was once attached to the top of a steel pole and some of theseremain in situ along the former telegraph line. Telegraphic communication commenced at the Gabo Lightstation in 1870, just eight years after the lightstation opened.The line from Sydney reached Eden, NSW by 1868 and was then extended to Gabo with the costs shared equally by NSW and Victoria. It was initially carried on posts across the sea to the island but was changed to a line along the seabed after the posts were washed away. The first telegraph office was a timber building on east side of the assistants’ quarters. In 1887 a new concrete telegraph office was built which included quarters for the operator, with Victoria and NSW sharing the construction costs. The 1992 CMP identified remnants of the line from its various phases of operation,231 and these can still be seen in 2016. Other ceramic insulators in the collection are associated with lines supported on utility poles for the transmission of high voltage electricity.

Modern communications technology arrived on Gabo Island with the construction of the telegraph line from Eden to Gabo Island in 1870. This type of insulator was usually used with radio antennae wires, telegraph and radio antennae equipment. The items of telegraphic equipment comprise a number of ceramic and glass insulators of varying age and type. Five, knuckle-shaped white glazed ceramic examples are associated with radio antennae wires. In addition to insulators, there is a telephone insulator bracket made of metal with wooden pins.

White Porcelain “Made in Occupied Japan” electrical insulators. Insulators can be dated from September 1945 to April 1952 during the allied occupation of post WWII Japan. Pin insulators were manufactured specifically for Australian export. Pin insulators are made of non-conductive porcelain and were used to create a barrier between outer wrapped suspended wiring and threaded wood or metal dowel. Pin insulators such these have been found on utility poles around Australia.Porcelain insulators stamped with “Made in Occupied Japan” are often viewed with much interest by collectors given their connection to WWII and short seven year manufacturing time span. Pin insulators such as these are an example of Australia’s continued electronic development which began in the late 19th century. Collection of seven white porcelain insulators made in Occupied Japan. Insulators are cylindrical in shape, with indentation at top. The indentation creates a flat mushroom top head. Insulators display a manufacturer stamp at the bottom of the cylinder. Insulators are single walled and hollow inside with threading at the enclosed top end. flagstaff hill, warrnambool, maritime village, maritime museum, flagstaff hill maritime museum & village, shipwreck coast, great ocean road, insulators, porcelain, electrical insulators, occupied japan

Items show two different wire terminations - fully wrapped - 7 wires and part wrapped and secured by bending the wire. Shows how the galvanized span wire - 7 strands - can corrode within the insulator and lead to failure if not inspected and replaced.

Modern communication technologyarrived on gabo Island with the construction of the telegraph line from Eden to Gabo Island in 1870. The insulator is associated with the telegraph station. Used at the H.F Radio Beacon. The items of telegraphic equipment comprise a number of ceramic and glass insulators of varying age and type. In addition to insulators, there is a telephone insulator bracket made of metal with wooden pins. It was once attached to the top of a steel pole and some of these remain in situ along the former telegraph line (0044). Telegraphic communication commenced at the Gabo Lightstation in 1870, just eight years after the lightstation opened. The line from Sydney reached Eden, NSW by 1868 and was then extended to Gabo with the costs shared equally by NSW and Victoria. It was initially carried on posts across the sea to the island but was changed to a line along the seabed after the posts were washed away. The first telegraph office was a timber building on east side of the assistants’ quarters. In 1887 a new concrete telegraph office was built which included quarters for the operator, with Victoria and NSW sharing the construction costs. The 1992 CMP identified remnants of the line from its various phases of operation,and these were seen in 2016. Other ceramic insulators in the collection are associated with lines supported on utility poles for the transmission of high voltage electricity. The various insulators have second level significance for their historic value and provenanceFour armed cross shaped insulator with two holes through diagonally opposite sections. It is ceramic with a clear glaze.

The ceramic insulators were used by the PMG to insulate telephone lines connecting to the lightstation accommodation. The installation of a single galvanised wire telegraph line in 1873 provided the lightstation with a vital link to the outside world via Morse code. In 1875, the Australasian Sketcher reported on the new facility, writing that ‘the lighthouse on the extreme point of the promontory is connected with Melbourne by a line of telegraph, and as a large number of vessels pass in sight of the lighthouse, useful information is gained respecting their movements’.The system was immobilised in 1885 when a thunderstorm caused some of the poles to explode and connection wires to fuse and turn into molten metal. During WWII the lighthouse line was upgraded to four copper wires, and in 1971 a radio link replaced the line. The lines required constant maintenance. Some poles remain along the length of the promontory’s Telegraph Track as reminders of this former communication link. Insulators can also be found in the collections at Cape Schanck; Cape Otway and Gabo Island. Comprises a white ceramic insulator attached to a rectangular metal plate.
