—Brief introduction of OIP bushingsand Features

—Our company

ABB has more than 100 years history of bushing

manufacture technology up to now, and has

developed into one of the key market leaders

providing a comprehensive range of high voltage

bushings and high grade service to meet the

demands of all applications. Oil-impregnated

paper (OIP) bushings of the ABB group have a long

and successful history, especially on extra and

ultra high voltage levels wher e service experience

and mature technology is most crucial. In 2008,

ABB 1100 kV OIP condenser bushings were

successfully used in China’s first UHV 1000 kV

project line, Jindongnan-Nanyang-Jingmen. As the

world’s largest bushing manufacturer, ABB group

owns bushing manufacturing units located all

around the world, including Sweden, Switzerland,

Russia, America, Brazil, India and China.

ABB Hefei Transformer Co., Ltd was the first

power transformer joint venture set up by the ABB

group in China in 1992 with the total investment

up to 30 million USD. It became a wholly owned

company by ABB in May, 2005 with more than 400

employees. At present, the company is organized

into two product groups: Product Group Insulation

& Components and Distribution transformers.

ABB Hefei Product Group Insulation & Components

(PGIC) is an independent unit of ABB Hefei

Transformer Co., Ltd, and a manufacture and

supply centre in China and Asia-Pacific region,

established by ABB group to serve the local

market.

Our main products are: On-load tap-changer,

Transformer bushings (RIP, OIP), Oil treatment

plants, Measurement and safety devices. Among

them, On-load Tap-changers, OIP Bushings were

technique transferred and authorized by ABB

Insulation and Components in Sweden. RIP Dry-

type Bushings and Oil treatment plants were

technique transferred and authorized by ABB

(Micafil) Co., Ltd in Switzerland.

As one of the most comprehensive range of

transformer components production and supply

center of ABB group, ABB Hefei PGIC has become

one of the main suppliers providing high quality

transformer components in both domestic and

overseas market.

ABB Hefei Product Group Insulation & Components

(PGIC), belongs to ABB Hefei transformer Co., Ltd

introduced advanced technique and production

echnologies of OIP bushings from ABB

Components, Sweden in 2007, including design,

equipment, production processes, core materials,

test equipment etc. Localized parts are tested and

approved by ABB’s material test laboratory in

Sweden. The performance of bushings produced

by Hefei is equal to bushings produced by ABB

Components in Sweden, completely satisfying

requirements from the Chinese market.

Range of OIP bushings in ABB Hefei:

52 kV to 550 kV Transformer OIP bushings

Transformer OIP bushing Product manual

High dielectric reliability

�Partial discharge <5Pc at Um.

�Lower dielectric losses over the bushing’s entire

service life.

�Uniform electric field distribution, simulating

electric field distribution by finite element

method.

�External insulation with good pollution

performance.

Perfect thermal stability

�Hot spots in the condenser core are calculated

by Finite Element Method, to select conductor

size correctly.

�The finest quality paper with low dielectric

dissipation factor is used to assure long life.

�Advanced equipment and process for winding

machine assure low dielectric losses.

High mechanical strength

�Withstand cantilever operating load: heavy load

of level II.

�Withstand high seismic stress: ZPA 0.3 g.

Reliable sealing system

�Excellent sealing structure, oil and heat resistant

gaskets with -40°C brittleness point.

�Strict quality and process control to verify the

tightness of all parts individually, as well as the

complete system during the final testing, no

sign of leakage is allowed.

�An adequate press force on the sealing structure

assures permanent sealing during all service

conditions.

GOE features

A set of concentric tubes are pre stressed and

serve as springs which hold the main bushing

components together and provide adequate

pressure on the gaskets in all expected

temperature and load conditions.

The annular space formed between the tubes

makes an efficient cooling duct for dissipation of

the heat, thus improving the current-carrying

capacity and thermal stability of the bushing.

The bushing is designed to be mounted at an

angle of up to 30° to 60° from the vertical. A higher

inclination can be obtained on request. The

current shall be reduced for horizontal mounting

and up to 15°from horizontal.

The top housing is made of aluminum alloy and

has expansion space for the oil, sufficient for

temperature variations in the bushing between -

40°C and +80°C. Variations in the length of the

centre tube and the housing are compensated by a

flexible connection inside the top housing.

The upper insulator on bushings GOE 1050 and

larger are equipped with retaining rings mounted

with stainless steel details.

Shed profile

The shed profile for all GOE bushings is of the anti-

fog type with alternating long and short sheds.

The shed profile is designed according to IEC

60815.For each pair of sheds, the ratio between

nominal creepage distance and the axial length is

4.0. This shed profile is developed and tested

specially for heavy

pollution.

—Bushing on-line monitor and adapter

GOE bushings are designed with voltage tap, TOB and TOM

bushings are designed with test tap, both can be used for

online bushing monitoring.

The voltage tap can be used for measurement of partial

discharge, dissipation factor, and capacitance values. It can

also provide a voltage source while the bushing is in

operation. The max. power-frequency voltage withstand test

with tap to earth is 20 kV, one minute, 50 Hz.

If needed, customer can select TOB(2)/TOM bushings with

specially designed voltage tap. These kind of bushings have

C1 conducting layer and C2 conducting layer in condenser

core. The voltage tap is internally connected to C1 conducting

layer whereas the C2 conducting layer is permanently

connected to mounting flange. Under online bushing

monitoring, C2 conducting layer is always grounded via

earthed mounting flange.
