The AEIC''s cable specifications and guides give vital information for manufacturers of electrical cables, while providing the electric industry and other electrical system users with clear and
The main clauses of the guide are organized by cable type and each of these clauses has been organized to match the general steps involved in the design process for a substation cable system (see Annex A for a flowchart diagram). Common information for each type of cable is placed in the annexes and is referenced from the body of the guide.
It is preferable to store the cable inside if UV protection cannot be provided. If the cable manufacturer’s recommended maximum pulling tension, sidewall pressure, or the minimum bending or training radius is violated, damage could occur to the cable conductor, insulation, shield, or jacket.
The cable to be used in this example installation is 3-1/c 750 kcmil triplexed aluminum cable with 1/3 concentric neutral. The completed weight of this cable is 78.4 N/m (5.375 lb/ft) and the OD for each cable is 4.09 cm (1.61 in). Plastic conduit suitable for direct burial (Type DB) is to be used for this example installation.
Installation of different voltage classes of medium-voltage power cables in separate raceways is also recommended. Cables installed in stacked cable trays should be arranged by descending voltage levels, with the higher voltages at the top. Utilization of armored shielded cables (separate raceways are still recommended).
Cable tray sections should be permanently identified with the tray section number as required by the drawings or construction specifications. The type and spacing of cable tray supports will depend on the loads. Tray sections should be supported near section ends and at fittings such as tees, crosses, and elbows. Refer to NEMA VE 1-2002 [B93].
When the earth resistivity is not known, a value of 90 °C cm/W is suggested in IEEE Std 835. The ampacity of below-grade cable is also dependent upon the load factor, which is the ratio of the average current over a designated period of time to the peak current occurring in that period.
