Overview

The ABB 2702A1A 25kV 200 Amp Loadbreak Extended Bushing Insert is a fully rated feed-thru bushing insert designed for medium-voltage electrical distribution systems. This insert features two 25kV class, 200 Amp loadbreak bushing interfaces, enabling reliable electrical connections in demanding utility and industrial environments. The fully rotatable design allows for 360-degree positioning, optimizing cable routing and installation flexibility while maintaining secure feed-thru functionality. Key specifications include a maximum phase-to-ground operating voltage of 15.2kV, phase-to-phase voltage of 26.3kV, and a basic impulse insulation level (BIL) of 125kV. The insert withstands 40kV AC for one minute and 78kV DC for 15 minutes, with a corona extinction rating of 19kV AC at 3pC sensitivity. It supports continuous and loadbreak operation at 200 Amps and handles momentary fault close at 10kA symmetrical for 10 cycles. The 2702A1A includes a bail assembly for secure attachment to ANSI standard bushing wells (conforming to ANSI Std. 386, Fig. 3), transforming radial-feed transformers into loop-feed units. Additional components supplied are a protective shipping cap (2701-41), lubricant (82-08), and installation instructions (IS-0114). The insert is compatible with shielded cable connections in sub-surface transformers, pad-mounted transformers, generators, switchgear, regulators, and reclosers. Applications include creating tap positions in existing apparatus installations, adding elbow arrester connections, and enabling loop-feed configurations in medium-voltage distribution networks. The peroxide-cured insulation and jacket ensure long-term reliability in harsh operating conditions.
