Abstract

540,300. Transformers. STANDARD TELEPHONES & CABLES, Ltd., and LEE, E. C. April 10, 1940, No. 6471. [Class 38 (ii)] [Also in Group XXXVI] The space surrounding a cable joint, transformer, or other electrical apparatus or surrounding the plates of a condenser in a casing is filled with plastic insulation by first introducing a liquid solvent for the plastic and then forcing in the plastic to displace the liquid. A barrier joint for high tension cable is built up by wrapping impregnated tape 6 over the joint 5 while basting with monomeric styrene as described in Specification 504,720, [Group XXXVI], covering the insulation with a layer of metal foil 8 bonded to the sheaths 9, 10 of the cables, lapping cotton tape 11 impregnated with rubber and polystyrene to seal the cable ends, and then filling the space 18 with monomeric styrene, methyl methacrylate, or benzene, and displacing this by forcing in polystyrene plasticized in accordance with Specification 490,814, [Group IV]. Another form of joint for multicore cables and an insulated cable termination are described. In each case a filler opening 17 and an outlet or outlets 15, 16 are provided. Another combination of plastic filling and liquid solvent is shellac used with methylated spirit.
