Internally fused capacitor units

Eaton's patented design ensures individually protected elements and prevents cascading failure. Polymer fuse tubes with isolated mounting avoids damage to adjacent components. Paperless design eliminates the generation of extensive carbon arc byproducts in the dielectric fluid. Fuse operation reduces stored parallel-element energy from being discharged into the fault, which minimises gas contamination and further damage, resulting in life extension and improved dielectric performance.

Dielectric system utilising polypropylene film and proprietary Edisol VI fluid achieves industry-leading ambient temperature applications. Each unit is individually monitored in a closed loop fluid impregnation system to prevent contamination. Fluid impregnation and gas molecule evacuation is superior to batch fill designs, resulting in reduced infantile failure rates and lasting performance. Leak and performance testing is conducted on 100% of units at three key manufacturing gates to assure product integrity.

Eaton's capacitor units are designed, constructed and tested to provide unparalleled performance in the harshest environments. The tank is constructed from titanium stabilised 409 stainless steel, robotically welded and painted with epoxy primer and urethane topcoat. This construction features a copper impregnation fill tube, nickel plated terminals and patented bonding techniques. Extra creepage bushings are available for contaminated and high altitude needs. Units are validated to ANSI C57.12.29 coastal environment standard.
