Description

Description

Standards

  • Product
    ASTM B 3; ASTM B 496; ICEA S-94-649

Application

Medium Voltage single core cables are used in electrical energy distribution networks, as feeders for transformers in substations, industrial facilities and urbanizations. They are suitable for installations in dry or wet locations, outdoors, underground ducts or directly buried in earth.

 

Ampacity and Reactance Conditions

  • Ampacities of Insulated Single Copper Conductor Isolated in Air Based on Conductor Temperatures of 90° C and Ambient Air Temperature of 40°C. According to NEC, Table 310.60(C)(69).
  • Ampacities of Three Single-Insulated Copper Conductors in Underground Electrical Ducts (Three Conductors per Electrical Duct) Based on Ambient Earth Temperature of 20°C, 100% Load Factor, Thermal Resistance (RHO) of 90, Conductor Temperatures of 90°C. According to NEC, Table 310.60(C)(77).
  • Reactance Inductive to 90°C, 60Hz, 3 conductors spaced 1 diameter. Trifoil and flat configuration

NOTE:

  • The data reported here are nominal and are subject to tolerances according to standards and normal manufacturing practices.
  • Other configurations not specified in this catalog may be available under special request and minimum manufacturing quantitie.

RECOMMENDATIONS FOR THE SELECTION OF ACCESSORIES AND DUCTS

The technical information presented here is for reference purposes only. Actual dimensions and construction details will only be available with the test reports for each manufacturing order. For the selection of accessories and/or ducts, it is recommended to measure directly on the actual dimensions of the cable using the appropriate methods and instruments. Centelsa by Nexans will not assume any responsibility for the selection of such elements.
