Design Control
Design and development planning
Standard design are those designs within the scope of the standard design programs and documented manual and spreadsheet-assisted calculation procedures. The implementation of plans for each standard design are the responsibility of the Order Development (ODEV) electrical and mechanical designers.

Special designs and development

Special design and development activities affecting product design are planned and implemented by the Engineering Manager and/or personnel assigned by him.
Process Control

This Policy applies to Danelecfze Facility Procedure
Control Limit for critical measurable parameters have been established for certain processes.
The required measurements, any special measurement tecchniques, control limits and measurement frequecy are documented on the system or in process operator or personnel collect and enter data on the system. when parameter fall outside establish control limit, the process measured is shut down and correstive action initiated per procedure.

  • Qualification Procedure
  • Stainless Steel Welding(Less than 1/8" thick)
  • Non-Ferrous Welding & Brazing.
  • Statistical Techniques

 

Inspection & Testing

Inspection of test may be performed at material receiving, during production, at final test and at final inspection before shipment of product. Various methods, such as stickers, tags, physical location in designated areas and computer entries, are used to clearly indicate the inspection or test status of materials and product throughout the process and ensure that non conforming product is not used or shipped to the customer.

Only product which has completed all required quality checks, or which has been released by the customer in accordance with our documented waiver procedure may be shipped.

Other procedure provides an overview of inspection and test status indication. The various procedures for manufacturing processes and quality checks give details to how inspection and test status are indicated.

Control of Quality Records

Quality records are maintained to demonstrate conformance to customer specified requirements and the effective operation of the quality system.

Our documented quality procedures define the quality records, who creates them and what form they are in. This information is distributed among the procedures which document processes initiating or adding information to quality records.

Quality records will be maintained in a readable form and filed to facilitate necessary retrieval. Ease of retrieval will be consistent with likely need for access. Most records are maintained in electronic form where practicable. All records will be documented in a legible form and stored properly to prevent loss or deterioration.

Quality records will be made available to our customers as required by contractual agreement.

Customer Supply Product

PURPOSE
Documents policy to verify, protect and control application of parts supplied by our customers.

Materials supplied by customers for use on their own units are handled using the same procedures as are used for materials purchase by Danelecfze, except that normal procedures for qualifying suppliers and maintaining qualification do not apply.

A special part number, which associates the part with the customer's shop order, is assigned and used on the purchase order to ensure the parts are issued only to the customer's unit.

Lost, demaged or non-conforming materials will be documented and reported to the customer.

Quality & Testing

The routine test are:

  • Voltage ratio and phase displacement IEC 60076-1
  • insulation resistant IEC 60076-3
  • Allied voltage test (Insulation to ground) IEC 60076-3
  • Induced voltage test (winding insulation) IEC 60076-3
  • No load loss test (winding insulation) IEC 60076-3
  • Winding Resistance IEC 60076-1
  • Inpendance and load loss test IEC 60076-1
  • Control Wiring auxillary operation.

Upon request, witness type/special test can be carried out:

  • Insulating Lighting Impulse test IEC 60076-2
  • Sound level test IEC 600551
  • Partial discharge test IEC 600270

Our production facilities where all transformer are manufacture are certified acc to ISO 9001 AND ISO 14001.

At the end of the manufacturing process the transformers are individually tested in accordance with the IEC standards.

Specially designed reinforce transformers suitable for pole mounting.Protected with arching horns are tested with accordance with SFS 2646 steep wave execution.

Management Responsibility
SCOPE.
This policy applies to the Danelec FZE facilities. PURPOSE. TO define quality policy. organization and management review policies related to the quality system. Quality POlicy The liquid filled transformer is dedicated to design and producing quality products which meet or exceed our customer requirement.Our ongoing commitment of quality is demostrated through measurement of annual organisation goals.Clear system definition and written procedures that must be adhere to maintain and continually improve our performance as a manufacturer of high quality product. Organization The organisation is structured so that attainment of quality objective is accomplish by those who have been assign the responsibility for performing the work. Responsibility and Authority
Within the documented authority,responsibility and organisational freedom to:
•Initiate action to prevent the occurance of product non-conformity.
•Initiate and record any product quality problems.
•Initiate,recommend and provide solution through designated channels.
•Verify the implementation of solution.
•Control further processing, delivery, or installation of nonconforming product untill the deficiency of unsatisfactory condition have been corrected.
