- Page 2 Foreword This guide is intended to address issues strictly relating to ELECTRO COMPOSITES (2008) ULC cycloaliphatic epoxy resin, dry type bushings for use on transformers, circuit breakers and reclosers. Issues relating to any other ELECTRO COMPOSITES (2008) ULC product should be addressed with ELECTRO COMPOSITES (2008) ULC Technical staff.
- Page 3 ELECTRO COMPOSITES (2008) ULC for assistance. GENERAL BUSHING INFORMATION ELECTRO COMPOSITES (2008) ULC Dry Type bushings are designed for use on transformers and oil circuit breaker applications, up to 170 kV voltage class and 5000A current rating. Bushings can be designed to conform to the following bushing standards: ...
- Page 4 Installation and maintenance of ELECTRO COMPOSITES (2008) ULC bushings is to be carried out by trained, certified and approved personnel only. Although ELECTRO COMPOSITES (2008) ULC bushings present no danger to personnel when not energized, reasonable care is to be taken when handling and transporting bushings.
- Page 5 Bushings are shipped horizontally or exceptionally at vertical position. As ELECTRO COMPOSITES (2008) ULC bushings are dry type (no oil or any other fluid components within the bushing construction), no special provisions are given for their shipping and storage other than given in this guide.
- Page 6 (2008) ULC REPRESENTATIVE IMMEDIATELY. DO NOT INSTALL THE BUSHINGS UNDER ANY CIRCUMSTANCES. STORAGE We recommend storing ELECTRO COMPOSITES (2008) ULC bushings indoors, in dry and normal room temperature conditions. However, if necessary, ELECTRO COMPOSITES (2008) ULC bushings can be stored outdoors (temperature range from -50°C to 60°C) if properly covered to maintain dryness.
- Page 7 METHOD 2 WITH ANCHOR SHACKLE IN FLANGE HOLES: METHOD 3 WITH A CHOKER ROPE OR SLING WELL BALANCED: Handle the bushing with care and take all necessary precautions to prevent it from falling or bumping into surrounding objects while it is being manipulated. Bushings may be top heavy or bottom heavy –...
- Page 8 Values measured at receiving should be used as a baseline to compare with future field measurements. Only C1 power factor and capacitance have meanings for bushings NOTE: Electro Composites (2008) ULC recommends against measuring C2 power factor and capacitance of our bushings for any purpose. Should C2 power factor capacitance...
- Page 9 ELECTRO COMPOSITES (2008) ULC bushings can be installed at any angle. A proper gasket is required between the flange and the equipment. In case of mounting problems, contact ELECTRO COMPOSITES (2008) ULC for further corrective action. Do not for any reason modify or alter any part of the bushing, including the aluminum flange.
- Page 10 CAPACITANCE TEST TAP The capacitance test tap is used for capacitance and power factor measurements. INSURE BUSHING IS NOT ENERGIZED PRIOR TO MEASUREMENT. The test tap is located on the bushing mounting flange. Generally, capacitance test taps are supplied only with transformer bushings. However, some users request them to be supplied with oil circuit breaker bushings as well.

Page 11: Maintenance
Any damage to a bushing, which might make repair either desirable or necessary, should be reported to ELECTRO COMPOSITES (2008) ULC. Typically, a small chip at the end of a shed will have very little effect on the bushing’s function. Do not try to fill chips with epoxy, as this will have no beneficial effects. - Page 12 RECOMMENDATIONS, DESCRIPTIONS, AND SAFETY NOTATIONS CONTAIN HEREIN. IN NO EVENT WILL ELECTRO COMPOSITES (2008) ULC BE RESPONSIBLE TO THE USER IN CONTRACT, IN TORT OR DELICT (INCLUDING NEGLIGENCE), STRICT LIABILITY OR OTHERWISE, OR FOR ANY DIRECT OR INDIRECT, INCIDENTAL, OR...
