Abstract

809,285. Moulding electrical switchgear components. REYROLLE & CO. Ltd., A. June 1, 1955, No. 15747/55. Class 87(2). [Also in Group XXXVI] A high voltage electrical switchgear component of the type comprising a conductor 10 embedded in a cast block 11 of polyester or ethoxylene resin and having one end of the conductor projecting into a re-entrant orifice 13, is made in a mould 15 having a flexible, neoprene, silicone rubber or irradiated polythene core 14 backed by a springy metal support 16. The core is held in position by a cover 17. Specification 743,002 [Group XXXV] is referred to.
