    Hello, The large round insulator is from a chain of old suspension insulators. You can still find these in use in some areas.

    The disk shaped insulators are high voltage suspension insulators that were connected together with metal links. There would be three to eight insulators in a string, depending on the voltage of the power line. The other two are guy strain insulators. They are used to insolate support cables, used to steady a pole or tower, from the ground.

    any idea the value of these?

    There are three sizes of Hewlett Suspension Disc Insulators, 10, 7 and 6 inch diameters. Yours looks like the 10 inch, I have seen these sell from $5 to $35, of course condition and markings affect value. I don't follow Hewletts closely, so I don't know all the variations in embossings and how they affect value. The guy wire strains, assuming they do not have a manufactures mark, would range between $1 and $10 each, closer to the $1 area.
