480TB / 484TB / 489TB Series
Nexans Euromold 480TB/484TB/489TB Compact T-Connectors
When a compact, asymmetric separable connector is needed for the same Interface C bushings as the 400TB/440TB symmetrical range, but across a wider conductor range, the Nexans Euromold 480TB, 484TB, and 489TB series is what we specify. Together they span 16 mm² up to 1200 mm² conductors across the 12–42 kV range.
About this product
The Nexans Euromold 480TB, 484TB, and 489TB series are compact, asymmetric screened separable T-connectors used to terminate polymeric-insulated medium-voltage cables onto Interface C bushings (per EN 50180 / EN 50181) in gas-insulated switchgear, transformers, and motors rated up to 42 kV. Continuous current rating is 630 A or 1250 A depending on the specific model and bushing interface used. This is not a single fixed value across the family, and should be confirmed against the exact order code rather than assumed from the family range alone. The 480TB family handles 16–300 mm² conductors (35–240 mm² on the 36 kV and 42 kV variants) with a 12.0–37.5 mm cable insulation diameter, making it the smallest-conductor option in this range. The 484TB family extends to 240–630 mm² conductors with a 23.5–56.0 mm insulation diameter; the 42 kV variant (P484TB) uses a slightly different insulation diameter than the rest of the 484TB family, so the exact figure should be confirmed per order code rather than read from the family range. The 489TB family covers the largest conductors in this range, 630–1200 mm², with a 40.0–68.0 mm insulation diameter. Both bolted and mechanical contact types are available depending on variant. Body material is EPDM rubber, accepting aluminium or copper conductors, with the same cable outer-sheath test capability and +MWS outdoor/humid-environment option as the rest of the Euromold separable connector range.
