PURPOSE
This standard is an introductory to the Underground Power Cable Construction
Standards (TCS-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 HV & EHV power cable systems in the network of Saudi
Electricity Company (SEC), Saudi Arabia.
2.0
SCOPE
The Underground Power Cable Construction Standards (TCS-P-104):
2.1
Reflects handling, storing 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
LV Cables (XLPE/PVC):
0.6/1 kV
2.2.2
MV, HV & EHV Cables (XLPE):
13.8 kV, 34.5 kV,
69 kV, 110 kV,
115 kV, 132 kV,
230 kV & 380 kV
2.2.3
Low Pressure Oil-Filled Cable (LPOF):
110 kV, 115 kV,
132 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 fieldtesting 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 TES-P-104, the
requirements in the latter shall prevail.
CODES, STANDARDS AND REFERENCES
3.1
Items not specifically covered in this standard (TCS-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 to ensure that the base
design or detailed design includes the requirements of the latest Industry
Codes and Standards. He can/may bring to the attention of SEC, any latest
revisions of these Codes and Standards which may have an impact on the
technical requirements of TCS-P-104.
3.3
Whenever different Codes and Standards are used, SEC 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 TCS-P104.
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 Transmission Materials Standard Specifications (TMSS).
4.3
SEC Transmission Engineering Standards TES-P-104.
4.4
This standard (TCS-P-104).
4.5

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 (TS&SD)
for any specific deviation from this Standard (TCS-P-104). This waiver
shall be taken for the deviation which is over-specification or underspecification.
5.2
In case of any deviations from this Standard (TCS-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 TS&SD, through concerned SEC
departments, before finalizing the design.
5.3
Any cases of conflicts or deviations which cannot be resolved shall be
referred to TS&SD who will be the final authority for correct
interpretation of the standards and associated documents, as applicable.
