Scope:

1.1
This Standard specifies requirements for 600 V copper and aluminum conductor secondary and service-entrance cables intended primarily for operation by electrical utilities. These cables are intended for underground installation
(a) by direct burial; or
(b) in conduit systems.
This Standard also applies to multiple-conductor cable assemblies.
Notes:
(1) The cables covered by this Standard are exposed to sunlight on terminal poles and during storage.
(2) The operation of cables complying with this Standard by other than an electrical utility can be subject to additional requirements by an authority having jurisdiction.

1.2
This Standard applies to cables with
(a) a maximum allowable conductor temperature of 75 °C or 90 °C; and
(b) cold impact and cold bend ratings of -40 °C.

1.3
Cables rated at 75 °C are suitable for voltage regulation limited applications where ampacity considerations are not applicable.

Cables rated at 90 °C are suitable for ampacity limited applications.

Project need:

To reaffirm the standard for its 5-year review
