Applications Overview

The NA2XS2Y is a single core aluminium medium voltage cable with cross-linked polyethylene (XLPE) insulation, copper wire screen, and a polyethylene (PE) oversheath. Its robust and UV-resistant oversheath makes this cable ideally suited for fixed outdoor installations where there may be an element of mechanical stress and sunlight exposure. Its properties allow the laying of this cable in winter conditions as cold as -20oC. It is widely used in the construction and power distribution industries.
We also supplies the NA2XS(F)2Y and NA2XS(FL)2Y with single and double layers water blocking tape for additional water resistance.

 

NA2SX2Y / NA2SX(F)2Y / NA2SX(FL)2Y voltage rating

The standard voltage ratings for this range of medium voltage cables is:
– 6/10kV
– 12/20kV
– 18/30kV

NA2XS2Y / NA2XS(F)2Y / NA2X(FL)2Y cable construction

Other than for its aluminium conductor, the NA2XS2Y shares the same cable construction as its copper variant, the N2XS2Y cable. Both cables are manufactured to VDE 0276-620, HDE 620 and DIN EN 60228.

This makes NA2XS2Y a cost-efficient alternative to its copper variant on installations where space is not an issue due to the larger overall diameter of aluminium cables.

NA2XS(F)2Y / NAXS(FL)2Y water blocking properties

NA2XS(F)2Y Swelling powder on tape Longitudinally watertight
NA2XS(FL)2Y Swelling powder on tape + Aluminium tape tightly bonded to the PE Sheath Longitudinally and radially watertight

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.

Hongda Cables is a leading supplier of medium voltage cables, which we consider to range between 3.3kV and 45kV. 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.

Custom designed medium voltage cables

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.
 

Medium Voltage cable testing

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.
