Telecommunications Buried Cable and Wire

The SAES-T-629 standard provides mandatory design requirements for the direct burial of telecommunications cable and wire. This standard ensures that the direct burial installations meet the necessary specifications and guidelines for reliable and efficient communication infrastructure. The standard covers various aspects of the design process, including cable selection, trenching, backfilling, and grounding. Compliance with SAES-T-629 helps ensure the proper installation and protection of telecommunications cables and wires when buried directly in the ground, reducing the risk of damage and maintaining the integrity of the communication system.

Design General Requirements

Design Requirements for OSP Telecommunications Cable and Wire Installation

4.1 General Requirements

4.1.1 OSP Design Reference

The BICSI Outside Plant Design Reference Manual (current version) is the recognized detailed design information for OSP design.
Design drawings should use conventional symbols as specified in SAES-T-018 Telecommunications – Symbols, Abbreviations, and Definitions.

4.1.2 OSP Designer Certification Requirements

Non-Aramco design offices must have a valid/current BICSI Registered Communications Distribution Design (RCDD) and/or OSP Specialty certification for OSP telecommunications system designs.
For external design contractors, the RCDD and/or OSP specialist must be a direct employee of the company.
Design drawings must be stamped by the RCDD and/or OSP specialist before the package can be Issued for Construction (IFC).

4.1.3 Cable Protection during Construction

Cables should be protected from being driven over by highway traffic, construction equipment, vehicles, or any activity that could damage the cable.
Direct buried telecommunication cables must be placed at minimum depths as specified in SAES-T-928.

4.1.4 Buried Cable Crossings of Streets, Roads, and Highways

Buried cable crossings of streets, roads, and highways must comply with SAES-T-928.

4.1.5 Road and Railroad Crossings

Road and railroad crossings must be constructed in accordance with SAES-T-928, SAES-T-911, and any relevant government requirements when government roads are involved.

4.1.6 Telecommunication Cables Near Power Facilities

Telecommunication cables placed near power facilities must be installed in accordance with SAES-T-928.

4.2 Joint Buried Cable Installation

4.2.1 Joint Trench Construction with Power Facilities

The “Random Separation” joint trench method is not allowed for joint trench construction with power facilities.
Joint buried construction with power facilities requires fixed separation as indicated in SAES-T-928.

4.2.2 Joint Pedestals for Power and Telecommunication Cables

Joint pedestals for power and telecommunication cables should not be used.
Telecommunication terminal housings/pedestals located within 3 m (10′) of power apparatus or vertical pole grounds (MGN) must have their grounding systems bonded together according to SAES-T-928.

4.2.3 Excavations and Restorations

All excavations and restorations must be carried out in accordance with the Saudi Aramco “Safety Management System (SMS).”

4.2.4 Electrical Station Protection

Electrical station protection should be installed in accordance with SAES-T-887.
Additional electrical protection requirements are outlined in SAES-T-887 and SAES-T-903.

4.4 Buried Cable Signs – Description and Installation

The installation information for buried/underground cable route marker posts and signs can be found in Saudi Aramco Drawing AB-036897.
Marker post/sign locations must be indicated on the construction drawings.
Marker/Identification tape should be placed in accordance with SAES-T-928.

4.5 Joint Buried Cable – Maintenance/Emergency Safety Precautions

4.5.1 Exposing Existing Communications Facilities

Existing communications facilities must always be exposed using hand digging.
Hand digging tools used should have handles made of wood or other materials with comparable insulating value.
If power cables are to be exposed, the Power Distribution Department (PDD)/Proponent should be present on-site prior to or during the excavation to provide appropriate advice.
Insulated rubber gloves, suitably certified, must be worn while digging and examining the markings and outside structure of the cables during the visual inspection of excavated cables.

4.5.1.1 Temporary Bonding

After identifying the proper telephone cable and before breaking the cable metallic shield, a temporary bond must be placed across the area to be opened to minimize differences in electrical potentials.

4.5.1.2 Handling Power Cables

Telecommunications personnel must not move or bend power cables at any time.
As stated in Para. 4.2.3.1, the Power Distribution Department/Proponent must be requested to identify and reposition power cables as necessary.

4.5.2 Damage to Power and Telecommunication Cables

In the event that both a power cable and a telecommunication cable are damaged in the same excavation, the power cable should typically be repaired first.
However, repair of the telecommunications cable must not begin until both the supervisor and PDD/Proponent have determined that safe working conditions have been restored.
