High-voltage hybrid switchgear Compact switchgear is fully assembled and high-voltage tested in the factory for rapid installation and energization. Bushings Composite bushings are used exclusively, as they are explosion-proof and resistant to pollution. Cable termination PASS can make use of cables instead of bushings. Combined disconnector/ earthing switch The gas-insulated combined DS/ES makes interlocking simple and intrinsically safe. Circuit-breaker The circuit-breaker is a single-break interrupter that operates by means of the self-blast principle. Circuit-breaker drive PASS is...
