Overview

The ABB 2702A1WB 25kV 200A Loadbreak Extended Bushing Insert is a fully rated feed-thru bushing insert designed for medium-voltage electrical applications. This insert provides two 25kV class, 200 Amp loadbreak bushing interfaces, enabling reliable electrical connections in power distribution systems. The fully rotatable design allows for 360-degree positioning, optimizing cable routing and installation flexibility while maintaining electrical integrity. The integrated bail assembly secures the feed-thru insert to the bushing well, preventing accidental dislodgement during operation or maintenance. Engineered to ANSI/IEEE Standard 386, the 2702A1WB supports a maximum phase-to-ground operating voltage of 15.2kV and phase-to-phase voltage of 26.3kV. It features a 125kV BIL impulse withstand rating (1.2 x 50 microsecond wave), 40kV AC one-minute withstand, and 78kV DC 15-minute withstand. The corona extinction voltage is rated at 19kV AC with 3p.C. sensitivity. The insert is rated for 200 Amp continuous and loadbreak operations, with a 10kA symmetrical momentary and fault close rating for 10 cycles. The 2702A1WB is designed to transform radial-feed transformers into loop-feed units, providing an extra tap for elbow arrester connections. It fits standard ANSI bushing well interfaces conforming to ANSI Std. 386, Fig. 3, and is compatible with ELASTIMOLD universal bushing wells. The product includes a feed-thru bushing insert, protective shipping cap, bail assembly, lubricant, and installation instructions. Applications include use as a bushing interface for connecting shielded cable to sub-surface transformers, pad-mounted transformers, generators, switchgear, regulators, and reclosers. The insert is ideal for substations, utility infrastructure, and industrial power systems requiring secure and adaptable loadbreak connections. The 2702A1WB ensures safe and efficient power flow, facilitating maintenance and upgrades with its user-friendly, rotatable design and secure attachment mechanism.
