LV & MV Power Cables
Medium Voltage Power Cable
Uni-Cable with a comprehensive range of Medium Voltage cables, our MV testing laboratory, and experts provide technical and regulatory advice. There are many options for construction, standards, and the materials used. The format can be single core or three core.
Selecting the right MV Cable for your project
Medium Voltage Cable Construction:
MV Cable Layer MV Cable Materials
Conductor Copper or Aluminium - Class 1 solid, Class 2 stranded (circular, circular compacted, sectorial). Some flexible MV cables for dynamic equipment are also available. 
Optional: Conductor Waterblocking Swellable powders or swellable yarns in stranded interstices
Conductor Screen Semi-Conductive Layer
Insulation XLPE (Cross-linked Polyethylene) or EPR (Ethylene Propylene Rubber)
Insulation Screen Semi-Conductive Layer
Optional: Waterblocking - Longitudinal Swellable powders or tape
Metallic Screen Copper Wires and/or Copper Tape (around individual cores)
Optional: Waterblocking - Longitudinal Swellable Tape
Optional: Inner Sheath Applied where Armour is also applied. PVC or LSZH compound
Optional: Armour Single Core: Aluminium Wires / Tape Multi-Core: Galvanised Steel Wires / Tape (Wires can be circular or flat, tapes can be single or double layer flat or corrugated)
Optional: Waterblocking - Radial Aluminium/PET Tape with the aluminum side tightly bonded to outer sheath
Outer Sheath LDPE, MDPE (Low/Medium Density Polyethylene), PVC (Polyvinyl Chloride), LSZH (Low Smoke Zero Halogen). Additives to offer resistance to UV, oils & greases, water, flames, termites, and other environmental factors can be added as required.

Medium Voltage Cable Standards:

MV Cable Standard MV Standard Description
IEC 60502-2 Cables with extruded insulation with voltage rating between 6kV and 30kV
BS6622 Armoured cable with PVC outer sheathing and voltage rating from 3.3/6kV to 19/33kV 
BS7835 Armoured cable with LSZH outer sheathing and voltage rating from 3.3/6kV to 19/33kV 
BS7870-4.10 Single core cables for distribution utilities with extruded insulation up to and including 11kV and 33kV
HD620 Cables with extruded insulation and voltage ratings 3.6/6 (7.2)kV to 20.8/36 (42)kV (often seen in conjunction with IEC60502-2)
DIN VDE 0276 Part 620 Distribution cables of nominal voltages 3.6kV to 20.8/36kV

MV Cable Nomenclature:

MV cables can be referred to by their standard and the materials used (eg: Cu for Copper, XLPE for Cross-linked Polyethylene) but they're often referred to by country-specific naming conventions. 
German MV Cable Nomenclature is:
N MV cable according to DIN VDE 0276
A Aluminium (Al) conductor
[blank] Copper (Cu) conductor
2X Cross-linked polyethylene (XLPE) insulation
S Screen of copper wires and copper tape, helically wound
SE Screen of copper wires and copper tape over each core, helically wound
(F) Longitudinal water tightness
(FL) Longitudinal and transversal (Radial) water tightness 
Y Polyvinyl Chloride (PVC) sheath
2Y Polyethylene (PE) sheath
H Low Smoke Zero Halogen (LSZH) sheath
