INTENDED USE

PEC ducts are used for the construction of underground duct system for fiber optic and copper cables in the telecommunication‘s long distance, junction, primary and secondary networks.

PEC ducts are used to provide a single and continuous duct laying operation from one point to another, e.g., manhole to manhole, without cut. It can be laid directly into trench at standard depths even without sand bedding. Concrete encasement is normally not required.

LONG TERM PERFORMANCE REQUIREMENTS

PEC ducts and its accessories suppuled in compulance with this specification, shall be capable of withstanding the typical service conditions of the Kingdom of Saudi Arabia for a minimum period of fifty (50) years without detriment to the operation and maintenance characteristics of the product.

PEC ducts and its accessories shall be designed, manufactured and packaged so that its physical or operation and maintenance characteristics shall not degrade when exposed to the environmental conditions of Saudi Arabia, and the expected environmental conditions during storage and transportation outside of the Kingdom.

The environmental conditions of Saudi Arabia may include ambient air temperature variations from -10º C to +55º C In addition direct solar radiation is known to increase the temperature of some outside plant to +70º C.
