For 5kV and 8kV medium voltage systems, cable selection often comes down to matching the voltage class, insulation level, conductor size, grounding, shielding, and armored construction required by the electrical design. This Type MC product group gives buyers a way to compare three-conductor EPR-insulated options with aluminum interlocked armor, red PVC jackets, and MV-105 temperature ratings before requesting a quote. The table below can help narrow the choice by conductor size, ground wire size, finished cable diameter, copper weight, and total armored cable weight.

5kV and 8kV Type MC cable is used for medium voltage power distribution where the project requires insulated conductors, shielding, grounding, and metal-clad mechanical protection in one cable assembly. It may be specified for commercial, industrial, utility, plant power, feeder, equipment, and infrastructure applications.
The correct cable depends on the system voltage, conductor size, insulation level, grounding method, installation conditions, and project specification.
The difference is the voltage class the cable is designed to support. A 5kV cable is selected for systems and specifications requiring a 5 kilovolt voltage rating, while an 8kV cable is selected where the electrical design requires an 8 kilovolt rating.
When choosing between them, buyers should follow the project specification and confirm the system voltage, insulation level, grounding method, fault-clearing requirements, conductor size, and installation environment.
Type MC stands for metal-clad cable. In medium voltage applications, Type MC cable includes insulated conductors inside a protective metallic armor assembly.
For this product group, the construction includes three conductors, EPR insulation, shielding, aluminum armor, grounding, a red PVC jacket, and an MV-105 rating. This type of construction may help provide mechanical protection and installation efficiency where armored medium voltage cable is specified.
Aluminum armor may be specified when a project needs mechanical protection with a lighter-weight armored construction. Interlocked aluminum armor can help protect the cable from physical damage while still allowing more flexibility than some rigid raceway methods.
The armor choice should be reviewed with the full cable specification, including voltage rating, insulation type, shielding, jacket material, grounding, installation method, and environmental conditions.
To request a quote, provide the voltage rating, conductor size, number of conductors, ground wire size, insulation level, shield requirement, armor type, jacket requirement, length, and any required project specifications.
For this product group, it is especially helpful to confirm whether the project requires 5kV or 8kV, Type MC construction, EPR insulation, MV-105 temperature rating, aluminum armor, red PVC jacket, and 100% or 133% insulation level.
