Product Description
MV Power Cables 6 – 35 KV PVC and XLPE Insulated
Commonly referred to as MV cables, medium voltage cable solutions include but aren’t limited to non-shielded and copper tape shielded type designs commonly found in many commercial and industrial applications.
MV Power Cables
Medium-voltage cables are mainly used to build weather-resistant networks and to improve the reliability of networks. The use of medium-voltage cables enables the transfer of power networks underground, which has proven to be a reliable method of avoiding any power failures caused by storms.
We offer a comprehensive range of Medium Voltage (MV) cables manufactured to various International Standards, British, European, including IEC 60502, BS6622. This British Standard sets out the specifications and required tests for single-core and three core armored cables with thermosetting insulation with a voltage rating ranging from 3.8/6.6kV up to 19/33kV. These cables are designed for a maximum operating temperature of 90oC for use in fixed installations including networks and industrial installations.
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 |
