Title: Improvements relating to condenser bushings
Inventor: DAVIES HAROLD
IPC: H02G15/107
Filed: 1962-10-22
Abstract: 1,056,279. Bushing insulators; passing conductors through partitions. MICANITE & INSULATORS CO. Ltd. Oct. 22, 1963 [Oct. 22, 1962], No. 39890/62. Headings H2C and H2E. [Also in Division B5] An electric bushing assembly comprising a conductor surrounded by an insulating body which is mainly composed of moulded synthetic resin material and which encloses at least one electrically unconnected condenser layer is made by assembling the condenser layer(s) in spaced coaxial relationship around the conductor within a mould, introducing the resin into the mould to cause the condenser layer(s) to become embedded within the resin and setting the resin so that the oreach condenser layer is supported in such a way as to avoid the presence of interfaces within the insulating body. The condenser layers may be of perforated tin or aluminium or of wire mesh or a wire-plastics combination or a conductive layer on a backing. In one method (Fig. 9, not shown) the mould is suitably shaped and lined with a resin coating 10 on its inner surface, condenser layers are positioned in it and embedded in resin 5, the coating 10 merging with the resin and forming the outer layer of the bushing so produced. In a further method, condenser layers 2 (Fig. 2, not shown) are held by a jig or cap 4 until they are supported at their lower ends by the setting of resin introduced into the mould 3 gradually or in steps in which case, after an initial introduction of resin into the mould a second introduction of a further resin is made into the lower end of the mould (Fig. 7, not shown) which further resin s of a faster setting type. The methods described may be employed for the production of bent bushings (Fig. 10, not shown) which may incorporate metal mesh earthed layers. Any suitable casting resin including a hardener with a filler and possibly an accelerator may be used unless an extrusion moulding process is employed in which case one of a number of thermoplastics resins may be suitably injected by means of a screw or ram.
