General Information
Overview
EN 50673:2019 specifies requirements for plug-in type bushings for 72.5 kV with rated currents of 630 A and 1 250 A used in electrical equipment (for example liquid‑filled transformers and gas‑insulated switchgear). The standard extends the scope of earlier plug‑in bushing documents (EN 50180 / EN 50181 series) to the 72.5 kV voltage class and defines dimensions, tests and interchangeability conditions to ensure reliable mating with separable connectors and extruded‑insulation power cables.
Key topics and technical requirements
- Scope and ratings
- Maximum system voltage: Um = 72.5 kV
- Rated currents: 630 A and 1 250 A
- Frequency range: 15 Hz to 60 Hz
- Interchangeability
- Establishes interface types (outside‑cone and inside‑cone) and dimensional requirements to ensure mechanical interchangeability between plug‑in bushings and separable connectors.
- Compliance is initially tied to the specific bushing + separable connector combination used in the type test.
- Procedures for extending approval to alternative combinations follow HD 629.1 S2 and dielectric re‑qualification per HD 632 series.
- Testing
- Type, routine and sample tests are performed in accordance with EN 60137 and relevant product standards (EN 60076, EN 62271, HD 632).
- Minimum dielectric test sequence for extension: partial discharge (ambient), 24 h power‑frequency at 2.5·U0, lightning impulse, 24 h at 2.5·U0, final partial discharge and component examination.
- Electrical and mechanical details
- Current‑carrying surfaces may be bare copper, silver‑coated copper, tin‑coated copper, or silver‑coated aluminium.
- High‑voltage shielding electrodes: design must allow venting in any installation position and not obstruct current‑carrying contacts.
- Ground shielding electrode inside the bushing must provide a grounding connection point.
- Mounting distances consider separable connector outer dimensions and handling clearances.
- Fixation
- Outside‑cone bushings for liquid‑filled transformers: flange ring and six clamping paw fixation (material guidance: 3 mm aluminium or non‑magnetic metal sheet).
- Inside‑cone bushings: no additional fixation means required.
Applications and who uses this standard
- Transformer manufacturers (liquid‑filled), GIS and switchgear designers, cable and separable‑connector manufacturers
- Test laboratories and certification bodies performing type, routine and sample tests
- Specifiers, procurement and asset owners who require interchangeability and standardized interfaces for high‑voltage terminations
- Installers and maintenance teams ensuring correct mounting, grounding and compatibility
