EBAC BUSHING ANSI STANDARD IEEE C57.19.01-2000
EBAC 69 kV BUSHING
Top Connector
EBAC Bushing Applications
• For transformers and oil circuit breakers • For interchangeable transformers/circuit breakers
EBAC Bushing Features
• One-piece solid cast insulation (no-oil) • Installation possible at any angle • Superior performance in earthquake zones compared to porcelain - very resistant to vibration • Robust - can be used in mobile equipment • Insensitive to moisture • Resistant to salt fog • High thermal index + 20°C extra margin over traditional OIP porcelain bushings - ideal for hot applications • Not affected by temperature variations • Less parts per bushing; simpler construction • Safe failure mode; does not explode like porcelain

Capacitance Tap
Flange
Applicable Standards
• IEEE C57.19.00-1991 • IEEE C57.19.01-1991 • IEEE C57.19.01-2000 • ISO 9001-2000
Shield
ECI EBAC bushings are designed to meet or exceed these standards.
Shed and Core Features
• Munsell 70 light gray color • Cycloaliphatic system - UV resistant and non-tracking • High dielectric value • Impact resistant • Solid dielectric core molded in one piece with integral shield • Fire retardant material- FV0 rated
Conductor
Bottom Connector
Draw Lead or Solid Connect Terminal Options
Draw Lead: • Connector can be designed for brazed or crimped configuration • Available in 400A draw-lead or 400/1200A interchangeable with bottom connect terminal • Bushing can be used with or without a bottom terminal
Fixed Copper Connector: • Lower end is supplied with different options such as NEMA blades or standard thread
Capacitance Tap
• The flange is made of machined high strength aluminum with a leak-proof seal between the bushing and the equipment • The test tap is integrated into the mounting flange • Capacitance taps come standard with transformer bushings; optional for breaker bushings • Ground shield connection is provided by a solid welded pin attachment • Shield positioning is optimized using electrostatic field calculation software
Bushing Name Plate
• Each bushing is routine tested for partial discharge, power factor, capacitance and dry withstand (hi-pot) • A detailed routine test report is provided with each bushing (100% testing and reporting) • A name plate is attached to the bushing flange providing information to the field personnel

ECI Reverse Engineering Service
ECI provides reverse engineering services for old bushings which are not ANSI compatible. Based on the dimensional characteristics and the electrical requirements, we can propose a model meeting your requirements and test it according to ANSI/IEEE standards.
Any non standard requirement, such as longer creep or higher temperature application, must be specified at the time of the request for quote.
To facilitate the process, fill out and send a copy of the form, on the opposite page, to our sales office.

EBAC SOLID INSULATION BUSHINGS FEATURES
The design features and characteristics of EBAC bushings provide many benefits and advantages over traditional OIP (Oil Impregnated Paper) porcelain bushings. Meeting standard IEEE C57.19.01 requirements: • Partial discharge values below 2pC (required value less than 25pC) resulting from void-free casting process, provides enhanced longevity • Bushing construction (cycloaliphatic resin body combined with dry type assembly) provides current overload capacity while maintaining maximum temperature rise limit • Can be stored and mounted at ANY angle since there is no oil • No oil reservoir required, therefore no oil-level maintenance • No need for stabilization period prior to installation - simply receive and install • Minimized environmental impact • Non-tracking insulation is suitable for more compact designs and allows for providing longer creep distances; optimized for highly pol- luted areas and more demanding applications: - salt fog (coastal and highways) - heavy industrial areas - continued UV exposure • Fire retardant material and no oil to burn provides added safety benefits • Safe failure mode – cycloaliphatic bushings do not explode like por- celain bushings • High resistance to damage – since bushings do not shatter under impact (dropped tool, gun shot), equipment operation is not compro- mised allowing for continued operation and minimized shut-downs • Insulation is moisture resistant (note that this type of material is often used to seal broken porcelain!) All ECI bushings are oil-free: • NO oil and NO PCBs
