This article is about Pedestal Installation And Pre-Commissioning for Telecom OSP Circuits of Building Telecom Distribution System as per International Codes and standards.
Pedestal Installation And Pre Commissioning – Telecom OSP Circuits
Installation
- Verify that extreme caution is being exercised when excavating near gas, oil and other hydrocarbon pipelines and buried power cables or conductors. No work shall start in the vicinity of these facilities until the proper work permits have been obtained and countersigned by the appropriate agencies including, PDD (Power Distribution Dept) where power cables are involved.
- Verify that existing facilities is always exposed by hand digging. Hand digging tools utilized shall have handles made of wood or other material having comparable insulating value. If power cables are to be exposed, PDD/Proponent should be on site prior to or during the excavation to advice as appropriate.
- Verify that the Pedestal is placed to a depth equal to the ground line marker located on the side of each pedestal.
- Verify that pedestal installation is not closer than 25 m to any pipeline in the corridor (refer to SAES-B-064).
- Verify that the shields and armors of all cables and service wires at the installed pedestals are bonded together, grounded, and continuous throughout. Refer to SAES-T-903 for bonding and grounding details.
- Verify that Telecommunication terminal housings/pedestals located within 3 m (10′) of power apparatus (transformer/pedestals etc.), or vertical pole grounds (MGN) shall have their grounding systems bonded together in accordance with SAES-T-928, paragraph 4.11.1.
- In areas where a terminal housing/pedestal is subject to disturbance/damage from vehicles, etc., verify that required proper pedestal guard is provided.
- Verify that installed pedestal guards are constructed of steel pipe or other metallic materials and they are bonded to the pedestal with a No. 6 AWG (16 mm²) solid copper wire which is attached to the pedestal guard (using cadweld method or an approved mechanical connector) at a point 50-75 mm above the concrete encasement of the metallic post base.
- Verify that installed Pedestal is grounded using a grounding electrode with a resistance of 25 ohms or less.
- Verify that the minimum number of mounting stake is provided on each pedestal.
- Verify that the installed ground rod for the pedestal is a minimum of 5/8″ in diameter x 8 ft. long in size.
- Verify that Pedestal stenciling and identification is in accordance with IFC drawings.
