1.0 PURPOSE

This chapter of the U/G Power Cable Construction Standards (SCS-P-104) is an introductory chapter to (SCS-P-104). It provides information on the requirements and practices which serve as the basis for the handling, storing, construction/installation, and testing of underground high voltage cable systems in the network of Saudi Electricity Company-Eastern Region Branch (SEC-ERB), Saudi Arabia.

2.0 SCOPE The U/G Power Cable Construction Standards (SCS-P-104):

2.1 Reflects handling, construction/installation and testing practices which are consistent with current industry standards with special consideration to the working environment in Saudi Arabia.

2.2 Covers the following types of cables and nominal voltage ratings. However, the

requirements and practices determined here can be adopted to all types of underground cable handling, construction and testing.

2.2.1 Cross-Linked Polyethylene Cable (XLPE): 69 kV, 115 kV & 230 kV. 2.2.2 Low Pressure Oil-Filled Cable (LPOF): 115 kV, 230 kV & 380 kV.

2.3 Explains in details the construction requirements which includes protection, support and maintenance of cable ducts and cable trenches.

2.4 Covers the installation procedures and the techniques for handling LPOF or XLPE

power cables. 2.5 Contains the installation requirements which are developed to govern the practices

and procedures to which the contractor shall adhere to in the installation of an underground cable system.

2.6 Indicates the proper techniques for handling and storing of cable reels.

2.7 Covers the applicable AC or DC tests as the effective method for the field- testing

of the power cable. 2.8 Covers the tests requirements after the installation of the power cable.

2.9 Does not cover the maintenance testing of the power cable 2.10 If any conflicts arise between this standard and SES-P-104, the requirements in the

later shall prevail.

3.0 CODES, STANDARDS AND REFERENCES

3.1 Items not specifically covered in this standard (SCS-P-104) shall be in accordance with the latest revision of the referenced Industry Codes and Standards.

3.2 It shall be the responsibility of the Design Engineer preparing the base design or

detailed design to be or become knowledgeable of the requirements of the latest Industry Codes and Standards referred in SCS-P-104. He shall bring to the attention of SEC-ERB, any latest revisions of these Codes and Standards which may have an impact on the technical requirements of SCS-P-104.

3.3 Whenever different Codes and Standards are used, SEC-ERB approval to the same

shall be obtained before proceeding with the design. These Codes and Standards shall be equal to or better than those specified in SCS-P-104.

4.0 ORDER OF PRECEDENCE

In case of any conflict between various documents and standards or specifications for U/G power cable projects, the order of precedence shall be as follows: 4.1 The Scope of Work and Technical Specifications (SOW/TS) for the project.

4.2 SEC-ERB Materials Standard Specifications (SMSS). 4.3 This standard (SCS-P-104). 4.4 Other applicable SEC-ERB Construction Standards (SCS). 4.5 Applicable Industry Codes and Standards.

5.0 DEVIATIONS

5.1 The Design Engineer who prepares the SOW/TS for the U/G power cable project is responsible to obtain an appropriate waiver from the Engineering Standards Committee (ESC) for any specific deviation from this Standard (SCS-P-104). This waiver shall be taken for the deviation which is over-specification or under-specification.

5.2 In case of any deviations from this Standard (SCS-P-104) during the Base Design

and detailed design of any U/G power cable project, it is the responsibility of the engineer preparing the base design or detailed design to obtain appropriate waiver from ESC, through concerned SEC-ERB departments, before finalizing the design.

5.3 Any cases of conflicts or deviations which cannot be resolved shall be referred to

ESC who will be the final authority for correct interpretation of the standards and associated documents, as applicable.
