Double Steel Industrial Power Cable Medium Voltage 1 Phase Cable 1kV To 100kV
Medium Voltage cables, or MV cables, is a category defined by the
International Electrotechnical Commission (IEC) as having a voltage
rating of above 1kV up to 100kV. There does, however, remain some
ambiguity over where the medium voltage cable band begins and ends,
depending on the countries, the standard setting bodies, and the
type of system used as historically engineers only referred to low
voltage and high voltage. The concept of medium voltage was only
introduced as the level of voltages increased and the need arose
for a greater classification range, which now often includes extra
low and extra high voltage.
Cables is a leading supplier of medium voltage cables, which we
consider to range between 3.3kV and 45kV. For higher voltages,
please visit our high voltage cable specifications to find the
right cable for your application. Our MV XLPE insulated cables are
manufactured in accordance with various British and international
Standards. These include armoured cable to British Standard BS6622
and BS7835; international Standards including IEC 60502-1 and IEC
60502-2; as well as a wide range of international construction
specifications, including N2SXY, N2XS2Y, N2XSEY, NA2XSY and
NA2XS2Y.

As a specialist MV cable supplier, our standard medium voltage
cable portfolio contains cable with single and 3-core copper or
aluminium conductors, with a steel wire armour or aluminium wire
armour for mechanical protection, and with various
application-specific materials including Polyvinyl Chloride (PVC),
Polyethylene (PE), Cross-linked Polyethylene (XLPE) and Ethylene
Propylene Rubber (EPR) and oversheathing properties including Low
Smoke Zero Halogen (LSZH). We also supply medium voltage standard
cables manufactured against specific power network requirements
supplied in triplex formation. Our MV cable products are installed
across a number of industries ranging from construction to power
transmission. They are widely used for power distribution between
high voltage mains power supply and low voltage applications, as
well as by utility companies to connect residential and industrial
complexes, or renewable energy sources such as wind and solar
farms, to the primary grid.
Our MV cables are available in specific lengths as well as in
extended long lengths to facilitate installation and to reduce the
number of joints.
In addition to standard medium voltage cables, we can design and
supply bespoke MV cable products developed for your specific
applications. Our custom designed cable solutions provide for
variants developed and manufactured around a number of parameters,
including:
Cross-sectional area: generally 35mm2 up to 100mm2
Number of cores: generally one or three
Solid or stranded aluminium conductors: for applications requiring
a lighter cable weight, also often more economical due to lower
aluminium prices.
Stranded copper conductors: for applications requiring a smaller
overall diameter and higher transmitting properties.
Bedding
Bonded or strippable out semi-conducting layer
Water tightness: longitudinal, longitudinal + quasi-radial,
longitudinal + radial
Insulation layers (conductor screen, insulation and insulation
screen): XLPE, which is more commonly used for MV cables, or EPR
which is more flexible and often better suited to marine and
offshore applications.
Metallic screen: to nullify the electric field outside the MV
cable. Concentric copper wire screens, Aluminium foil laminate, or
extruded lead alloy sheath.
Twisted three-core cable or triplex
Armouring: for mechanical protection. Aluminium wire armoured for
single-core cables, Galvanised steel wire armour, strip or tape.
Tapes: Separator tapes to facilitate peeling, water-swellable tapes
to prevent water ingress, Conductive tape for core binding.
Outer Sheath: compounds with various properties, tailored to the
specific application's requirements, including resistance to oils,
greases, rodents, termites, UV and flame, as well as zero halogen
emissions.
Our medium voltage cables including our BS6622 and BS7835 standard cables are tested by the Cable Lab®, our in-house specialist cable testing laboratory accredited by UKAS to ISO 17025. We perform tests on our cables against relevant British and international Standards, and against the requirements of your application when providing customised cable solutions.
Some of the tests you would expect from a medium voltage cable
manufacturer, and which are performed on our MV cables, include:
Routine tests: These non-destructive tests are normally carried out
on all lengths manufactured.
- Conductor resistivity
- Spark test on oversheath
- Voltage tests on sheath
- D.C. voltage test on oversheath
Sample tests: These potentially destructive tests are normally
carried out on every production run.
- Examination of conductor and dimensions
- Hot set test for XLPE insulation
- Insulation and oversheath thickness
- Four hour voltage test
Type tests: These destructive tests are normally carried out in
addition to the above tests on commencement of a particular cable
supply to validate its design.
- Electrical type tests including bending and heat cycle
- Non-electrical type tests including mechanical properties after
ageing and tests under fire conditions.
To ensure the optimal performance of our Medium Voltage cables as part of a system, we also supply a comprehensive range of MV cable accessories, including jointing kits, terminations, connectors and lugs.
