The Hubbell 15 kV 200 A Loadbreak System (Hubbell Power Systems / CHANCE) is an industry-standard separable insulated connector system designed per IEEE Std 386 for underground medium-voltage distribution.
Voltage Class: 15 kV (8.3 kV AC Max Phase-to-Ground / 14.4 kV AC Phase-to-Phase)
Continuous / Switching Current: 200 A RMS continuous with full loadbreak/loadmake capability
Fault Close Rating: 10,000 A RMS symmetrical for 0.17 seconds (10 operations per IEEE 386)
Basic Impulse Level (BIL): 95 kV Crest
Withstand Voltages: 34 kV AC (1 min) / 53 kV DC (15 min)
Corona Extinction: 11 kV minimum ($<3\text{ pC}$)
215LE Series Loadbreak Elbows: Molded EPDM connectors (with or without capacitive test points) that terminate underground solid-dielectric cable (XLPE/EPR).
215BI Bushing Inserts: Threads into standard 15 kV/25 kV universal apparatus bushing wells on pad-mount transformers and switchgear to create the loadbreak interface.
215FT Feed-Thru Inserts & Junctions: Multi-point loadbreak junctions used in pad-mounted sectionalizing cabinets for loop-feed taps and temporary bypasses.
215DR Insulated Protective Caps / Standoff Plugs: For parking, dead-ending, and isolating energized or de-energized loadbreak elbows.
