MV Cable voltage required (details, specifications”
⚡ Saudi Standards for MV Cables
Saudi Aramco and SEC (Saudi Electricity Company) follow specific engineering standards:
📘 Key Documents:
 SAES-P-104 – Wiring Methods and Materials
o Specifies design and installation requirements for MV cables.
o MV cables typically rated 5 kV to 35 kV.
o Installation must consider chemical resistance, insulation integrity, and
environmental conditions.
 15-SAMSS-502 – Medium Voltage Power Cable Specification
o Covers dielectric insulated cables rated 5 kV to 35 kV, 50/60 Hz.
o Requires compliance with IEC 60502-2, ICEA S-94-649, and AEIC CS8 standards.
o Insulation thickness and conductor sizing must match fault current and load
requirements.
 SEC SDMS Series – Distribution Material Specifications
o For example, 56-SDMS-08 outlines MV substation components rated 13.8 kV or 33
kV.
🌍 International Standards for MV Cables
📘 IEC Standards:
 IEC 60502-2 – Power cables with extruded insulation for voltages from 6 kV to 30 kV
o Defines insulation, conductor material, voltage ratings, and testing protocols.
o Rated voltages: 6/10 kV, 8.7/15 kV, 12/20 kV, 18/30 kV, 19/33 kV.
📘 AEIC & ICEA Standards:
 AEIC CS8 – Shielded Power Cables Rated 5–46 kV
 ICEA S-94-649 / S-97-682 – Utility Shielded Power Cables
These standards ensure:
 Proper insulation and shielding
 Voltage withstand capability
 Fault current endurance
 Environmental resilience (moisture, heat, mechanical stress)
