Bullers 864

bullers insulator

This insulator was one of three fixed to an old pole transformer box. The top section down to the first flange is fixed inside the box via a lot of bitumen and a bolt which runs through the centre, poking out of the bottom where a brass nut holds the whole assembly in place. The power wire is then affixed to the remaining stub of thread.

A nice clear printed mark graces the second shed.


I assume this represents the date of manufacture, January 1973 and a pattern number 864.

Overal dimensions are 7.1/4 inches high and 5.3/4 inches across the widest point.
