To-day we are able to show this massive 242 kV OIL FILLED BUSHING. The porcelain parts were made in Bullers’ works for the BritishThomson- Houston Co. Ltd. It measures 15 ft. ij inches overall and is one of the largest bushings of this kind yet produced. Only the skill and knowledge acquired by long experience could produce insulators of such dimensions free from flaws. How much larger will be called for in years to come, only the future can say. But one thing is certain, whatever the size, Bullers will be ready with their unrivalled resources and experience to cope with the problem.

Machines have to be fixed in awkward positions, switchgear has to be tucked away in a small cubby-hole, wiring is less conveniently placed for fixing under the new layout. Rawlplug Fixing Devices can solve all these fixing prob lems for you, simply and economically. There is a Rawlplug for every size of screw. They are suitable for any type of fixing work from electric wiring to fight machinery, and of course Rawl- plugs are quickly and securely fixed. Rawlbolts are the modem way of fixing heavy machinery —fixing it without fuss, without the mess and trouble of grouting.
