Transformer BushingsIEEE/ANSI Standard, COTA 150 – COTA 2050

®

ApplicationTrench bushings, Type COTA, are designed for application on liquid filled power transformers and reactors. They are used to connect the power transformer or reactor to overhead lines or exposed bus in either outdoor or indoor conditions.

Connection to the transformer winding leads can be accomplished by one of three methods:

Bottom connected via a fixed conductor.

Connected via a copper draw lead cable(s) supplied with the power transformer.

Bottom connected via Trench’s all copper “Split-Conductor” draw lead. (Up to 1300 kV BIL)

The method selected depends on voltage rating, maximum through current or user preference. Connection to the power system is accomplished with an industry standard threaded top terminal.

Applicable Standards

Trench bushings Type COTA, are designed to meet or exceed the following industry standards for liquid filled power transformer or reactor applications:

ANSI/IEEE Standard C57.19.00-2003IEEE Standard General Requirements and Test Procedure for Outdoor Power Apparatus Bushings

ANSI/IEEE Standard C57.19.01-2000IEEE Standard Performance Characteristics and Dimensions for Outdoor Apparatus Bushings

DesignActive Part

The active part of the COTA bushing is constructed of oil-impregnated paper with layers of aluminum foil. The position of the foil layers is computer optimized to ensure a homogenous electrical field, radially and axially controlled, providing extremely high dielectric resistance.

The Trench active part design ensures that COTA bushings will last the life of your power transformer.

Housing

The housing is constructed of a head, outdoor insulator, mounting flange, ground sleeve (COTA 250 and above) and epoxy or fiberglass insulator,held together by either a central tube or a fixed conductor. Pre-tensioned cone spring washers provide mechanical stability over the entire temperature range, ensuring a leak free bushing with the highest possible mechanical strength. COTA bushings are sealed exclusively with 0-Ring gaskets and each bushing is hermetically sealed with its own independent oil reservoir. The interior of the aluminum castings are painted.

Head

The cast aluminum head contains an oil expansion chamber with an oil level indicator. The design of the head allows the bushings to be shipped and stored horizontally and mounted as follows:

Outdoor Insulator

The outdoor insulator is either a high-grade electrotechnical porcelain or an insulator constructed from a explosion-resistant fiberglass epoxy resin tube with molded silicon-rubber sheds.

Porcelain Insulators

The standard porcelain insulator on COTA bushings is ANSI No.70, light gray. Brown porcelain is available upon request. One-piece porcelain is standard on COTA 150 though 750 and optional on COTA 900 and 1175. When the height of the bushing makes it necessary to use more than one porcelain element, Trench uses a special gluing procedure developed to ensure that the porcelain elements will exhibit the same levelof performance as a single porcelain element. On bushing style COTA 250 and above, the porcelain insulator is cemented to the mounting flange using special cement and sealed with an0-Ring gasket. To protect against corrosion, the mounting flange surface and porcelain that is in contact with the cement is treated with a special coating, ensuring a trouble free interface.

Silicone Rubber Insulators

Silicone rubber insulators used by Trench are specifically designed for use on high voltage bushings. These insulators demonstrate superior electrical and mechanical characteristics not found in other types of insulators. The physical properties of the silicone rubber provide many advantages over conventional porcelain insulators. The silicone rubber insulator has demonstrated superior performance in earthquake prone areas.

DesignMounting Flange

The mounting flange is a high quality aluminum casting, machined to exact dimensions, ensuring an excellent seal between the bushing and the transformer.

Integrated into the mounting flange of COTA bushings through 69 kV are test taps. Above 69 kV the mounting flange is equipped with a voltage tap.

Shatter Resistant Inboard End

Every Trench COTA bushing is offered with a shatter resistant in-board end insulator. These insulators are less susceptible to damage from handling. They will not shatter like porcelain preventing major transformer repair costs. Trench in-board end insulators have 25 years of proven field experience.The lower end of the COTA bushings (COTA 200 and below) are protected by an explosion resistant fiberglass-reinforced epoxy-resin tube or (COTA 250 and above) by a shatter resistant cone shaped vacuum molded epoxy resin insulator.

These insulators are designed to be installed during the in-tank drying process of the active part of the transformer and can withstand temperatures up to 130°C.

Embedded End Shield

(Draw Lead COTA 250 though 1175)

High voltage bushings require an end shield to control the electrical field strength at the inboard end of the bushing. Instead of mounting this shield externally, Trench embeds the shield in the epoxy-resin inboard end insulator. This provides a more uniform distribution of the electrical forces and reduces the required clearances. The embedded end shield provides greater interchangeability with other bushings, making the Trench COTA bushings the ideal replacement bushing.

Current Path

Two current path options are available:

Fixed conductorCurrent path via conductor that is fixed in place and has the active part wound on the conductor. The fixed conductor is either a solid rod or a tube, depending on the specific bushing design.

Draw leadCurrent path via the transformer’s cable(s) to a silver-plated copper terminal through multi spring contacts to the copper-alloy top terminal. Or via Trench’s copper “Split-Conductor” draw lead through multi spring contacts to the copper-alloy top terminal.

Fixed Conductor

When a fixed conductor bushing is selected, the connection to the transformer winding leads will be at the bottom of the bushing. The terminal configuration at the bottom of the fixed conductor bushing will depend on the current rating and/or the desired application and the requirements of the ANSI/IEEE Standards.

Draw Lead Cable(s)

When the application is less than 800 amperes, draw lead cable(s), provided with the transformer, can be used. For recommendations on selecting the draw lead cable(s) for COTA bushings refer to the Trench COTA Instruction Manual.

When applying draw lead cable(s) on bushings with a vacuum molded epoxy resin insulator the embedded end shield provides for a simple, space-saving assembly without additional shielding or barriers. Refer to the Trench COTA Instruction Manual for additional details on this feature.

“Split-Conductor” Super Draw Lead

Historically bushings through 69 kV only offered a draw lead rating of 400 amps. Today, using the Trench “Split-Conductor” in COTA bushings you now have draw lead ratings to 3,000 amps. Now, almost all medium power transformers through 100 MVA can have all draw lead bushings. The “Split-Conductor” draw lead feature provides increased safety for personnel, shorter installation times and ensures factory tested transformer lead connections.

For “Split-Conductor” applications the termination of the transformer or reactor winding leads will be at the bottom of the bushing. The type of termination required will depend on the maximum through current, operating voltage and mounting position. Additional measures (shielding, barriers, etc.) may be required. Contact Trench for available terminals and shields for your specific application of the “Split-Conductor”.

Top Terminal

Unlike other bushing designs, where the top terminal is threaded onto the bushing, the Trench COTA bushing utilizes a top terminal that is bolted to the head of the bushing. This feature eliminates the requirement to check the top terminal for tightness, increasing reliability and providing a truly maintenance free bushing.

The top terminal is designed to accept either a draw lead terminal or the Trench’s “Split-Conductor”.

On fixed conductor COTA bushings the top terminal is an integral part of the bushing’s conductor.

Quality

Everyone talks about quality; nearly everyone is ISO 9001 certified including Trench but that is not the whole picture. Quality starts at the beginning, it starts with the design. When you compare a Trench COTA bushing with other brands you will find quality design features not offered by the others. These include O-ring gaskets instead of flat gaskets, the interior of all castings painted, easy to read prismatic oil level indicators and stainless steel test tap caps just to mention a few.

Quality is the reason Trench offers the only standard three-year bushing warranty in the business. 85 years in the bushing business and still growing, Trench, the quality choice for bushings.

Standardization

Trench COTA bushings were developed to promote the concept of “standardization”. The designs detailed in this catalog will cover nearly 100% of the bushing requirements for liquid filled power transformers or reactors rated through 2500 MVA, three-phase, 2050 kV BIL. (Excluding high current bushings for GSU transformers) All COTA bushings though 900 kV BIL are designed for operation, without de-rating, to an altitude of 10,000 feet. COTA bushings above 900 kV BIL are offered with altitude ratings based on the BIL rating of the specific bushing. Example; a COTA 1050 may be rated for 10,000 feet while the same bushing rated at 1300 kV BIL will only be rated for operation at 3,300 feet.

COTA bushings (COTA 200 and above) have as standard, “extra-creep” porcelain in accordance with the heavy contamination level as described in the IEEE Guide for Application of Power Apparatus Bushings, C57.19.100-R2002.

COTA bushings present a level of standardization that will reduce inventories while meeting the most demanding requirements.
