3 Definitions
The following definitions shall apply in this Standard:
Aluminum conductor material (ACM) — AA-8000 series aluminum alloy conductor material in accordance with the physical and electrical requirements of ASTM B800.
Cable
Type UBC 90— underground secondary or service-entrance cable consisting of two, three, or four circuit conductors twisted together, one of which is an identified insulated neutral. Each conductor is insulated with XLPE and is unjacketed. Type UBC 90 is suitable for installation in conduit only.
Type UDB 90 — underground secondary or service-entrance cable consisting of two, three, or four circuit conductors twisted together, one of which is an identified insulated neutral. Each conductor is insulated with XLPE and is unjacketed. Type UDB 90 is suitable for direct burial or installation in conduit.
Type UNB 90 — underground secondary cable consisting of six phase conductors cabled around a neutral conductor. Each phase conductor is insulated with XLPE and may be jacketed or unjacketed. The neutral conductor may be bare or insulated with XLPE. Type UNS 90 is intended for secondary network systems.
Type USEI 75 — underground secondary or service-entrance cable consisting of two, three, or four circuit conductors twisted together, one of which is an identified neutral. Each conductor is insulated with thermoplastic or thermoset polyethylene and is jacketed with PVC. Type USEI 75 is suitable for direct burial or installation in ducts.
Type USEI 90 — underground secondary or service-entrance cable consisting of two, three, or four circuit conductors twisted together, one of which is an identified neutral. Each conductor is insulated with XLPE and is jacketed with PVC. Type USEI 90 is suitable for direct burial or installation in ducts.
Capability test — a test used to verify the capability of a parameter to meet specific requirements.
FinIshed length — a continuous length of cable or cable assembly, produced as a result of the final manufacturing process, before it is cut into shipping lengths.
Service-entrance cable — an underground cable used between a utility’s point of supply and a user’s service equipment.
4 General requirements
Unless otherwise specified in this Standard, cable shall comply with CSA C22.2 No. 52.
5 Quality management system
A quality management system consists of all planned and systematic actions that are necessary to ensure
that a product conforms to technical or performance-based requirements. The manufacturer should have
a quality management system in place that conforms to the requirements of an acceptable quality
program.
Note: An example of an acceptable quality program is one based on CAN/CSA4SO 9001.
6 Product qualification
Cable shall be tested in accordance with Clause 8. Product qualilication shall depend on evaluation of the test results.
Capability tests shall be performed every 10 years or when a cable component material or design is changed.
7 Construction
7.1 (;eneral
Types USEI 75 and USEI 90 cable shall comply with the material and construction requirements specified in
CSA C22.2 No. 52,
Types UBC 90, UDB 90, and UNB 90 cable shall comply with the material and construction requirements of this Standard.CSA C68.7-11 pdf free download.
