Design and Development is the integral part of the operation of TBEA Shenyang. This comes

under Design Department and it basically focuses on research, development and designing of

transformer products. As soon as a client submits his/her transformer technical and design

requirements, the team from International Department Project Management analyses andprepare documents for approval from superiors for book keeping. After the approval, the

technical specifications are passed on the Design Department. The design engineers carefully

study the clients technical specifications. The engineers then put a lot of effort to do research

and proceed with designing of the transformer following the technical specified with the

required Standards. Some of the standards applied in designing according to technical

specification are IEC, IEEE, AS, ANSI, NEMA among others.

The design is done within the time limit the client sets. The design process goes through

stages of being designed by the engineer, checked by senior engineer and then approved chief

engineer. Should there be clarification needed, our technical consultants and experts are

asked to give input to the design. During the design, the design engineers also take intoconsideration the technical specification of suitable transformer accessories. These are then

put forward to the purchasing department to for technical clarification and purchasing process

as outlined in Appendix 2. In the process of designing, the design engineers with the project

management team from the international department also liaise with relevant departments for

R&D and secure relevant information. The appendix 3 gives further information on design

and development procedures.

2.5 COATING AND PAINTING SYSTEMS OF TBEA SHENYANG

Specification for Coating Requirements of Load Transformers. See Appendix 4 for detail

information of the coating and painting system of TBEA Shenyang.

TBEA Shenyang can able to provide the coating system to supply protection against any

atmospheric corrosion however we can not specify how long it can last without need for

maintenance. From our experience, the painting can last for about 4 to 5 years but paint

maintenance can be done when realized that the products need paint maintenance.

TBEA Shenyang can design anti-corrosion coating as per clients requirement according to

the transformer installation site environment. Paints shall be applied in the shop in the frame

of SSPC PA1 and cannot apply field painting. Internal surfaces shall be painted as TBEA

Shenyang applies in some of its products.

TBEA Shenyang makes sure that all external and internal paints of any transformer product

are to be compatible with the transformer oil we supply. TBEA Shenyang has been in the

transformer industry for more than 70 years of experience with proven record to make sure

painting does not affect or deviate the quality of the transformer oil.

The cover painting for the transformer will be thicker and it can include anti skid solution.

Since we have so much experience for coating systems, we are able to do anti skid coating

system on the cover.

The outer top-layer shade shall be by RAL 7038 and internal shade is fair.

TBEA Shenyang will make sure the final product will be good looking, homogeneous, free

from leaks and the product will have a good adhesion to the transformer matrix.

For maintenance for the damages from shipment, it is recommended that the paint can be

taken to the site to repair the damaged part.

2.5.1 Coating Procedure DescriptionThis may include surface preparation and treatment for problematic areas.

2.5.1.1 Preparation before coating

Before the coating of metal surface, it must be thoroughly degreased, remove oxidizing and

other contaminating materials attached on the surface, so that the coating can adhere to stick

cohere reliably on the metal surface.

-18-


19/67

(a). Removing Oil

Should there be any greasy dirt discovered on the surface before the treatment of steel and

iron along with the painting of the product, we should proceed with oil removing process

immediately by dipping the cleaning rags in the toluene then wipe off thoroughly the greasy

dirt on the surface with the rags.

.

(b). Sand (Dirt) Blasting

(i). The transformer tank with all the accessories are kept in a closed door area and start

blasting the sand/dirt off.

(ii). After the blasting of steel and iron surfaces of the transformer and accessories, the steel

and iron are grayish white color that reaches the level Sa2.5.

(iii). Within 8 hours after the blasting of accessories, the coating process is applied to both

top and below of the surface.

(c). Pre-treatment of steel products

(i). Any product that uses steel should undergo the pretreatment process.

(ii). Pre treatment is applied to the welded parts of the tank that includes the welded joints.

The non homogeneous surfaces of welded joint parts, the greasy parts, and welded dregs are

thoroughly eliminated, thus revealing the true colors of steel and iron.

(d). Treatment of Acidic Phosphorization Cleaning

(i). Small and medium accessories along with long and large components are treated by the

use of acid cleaning Phosphorization process for treatment.

(ii). The coating process is applied to top and bottom surfaces within 48 hours of acidic

treatment on all the accessories (Besides the treatment of spare parts).

(e). The edge of tank and accessories - edge, joints and corners polishing process

(i). The top and bottom sections of the tank along with any elevated enclosure and any

similar surfaces are placed on gas cutting surface process to shear any plane that has exposed

edges and corners. This edging process must be done before the coating. The bevel edge

requirement is R3.

(ii). The top and bottom sections of tank are treated with any material that has not been

treated. After the treatment of the bottom material, there must be an abrade stain removal

processing. After the abrade processing surface condition, the colors of steel and iron

become real grayish white that can reach the Sa2.5 level.

20/67

2.5.1.2 Brush Painting

(a). For painting, firstly dip the paint brush in the paint then carry on with brush painting. It

must guarantee the paint film evenly and required thickness.

(b). On every product edge, bend angle, flange and the back of the flange border with otheredge spots on the surface are to be brush painted before the spray painting is applied to all the

surfaces including top, bottom, edges, joints and corners. The required width of the brush

painting is 150mm from edges and corner lines within the scope of the whole surface for

brush painting. The brush paint is not only applied to the flat surfaces but also edges, corner

lines and narrow spot of the scope.

(c). For Anti Corrosion Requirement of paint, the brush painting is applied to the whole

flange surface by using a method called brush coating. This creates the coating corrugation.

(d). After the brush and spray paintings of edges and corners, it is a must that all the sections

are painted thoroughly as line upon line. The spray and brush painting thickness control isapproximately about 40m. This can protect the edges and corners from rust.

2.6 TRANSPORTATION OF PRODUCTS

TBEA Shenyang has well organized and arranged equipment that can able to lift, move, load,

unload and transport transformer products. It makes sure that the products are handled with care

when lifting and loading. After the loading, the products are loaded on carriers according to their

sizes and transported to the port to be exported to the clients destination. Appendix 5 covers theTransportation System in detail from one point to another for delivery.

2.7 ACCEPTANCE AND STORAGE OF PRODUCTS

2.7.1 Acceptance and inspection

When a transformer product arrives at the designated site, immediate inspection and

acceptance are required. Acceptance items are as follows:

(i). No-load test

Before test, connect the signal contact of Bucholz relay to the trip circuit of transformer.

Over current protection shall react instantaneously. The source side of transformer is

provided with the protecting device. Connect source to that side of Transformer in order to

cut off the source in abnormal condition. Then raise the voltage slowly to the rated voltage.

Remain it for 30 minutes. Measure on-load loss and on-load current and compare them with

factory routine test.

(ii). No-load impulse test

First, reset the over current protection of Buchholz relay. When the protecting breaker is

switched on, phase timing difference is less than 0.01s. Impulse voltage is the rated system

voltage and is applied on HV side. The switching time of the breaker is not more than 5

times, During the impulse, voltage (including the first time impulse) once reaches the peak

value and the test is regarded as passed. If no peak value appears during the 5 impulse tests,

the impulse test is passed too. Neutral point shall be earthed for neutral point earthing

transformer.

(iii). If top oil temperature rise does not exceed 50k when the transformer is operated under

rated voltage for 6 hours at no-load, its not necessary to start coolers.
