Hyphen Cables are available with both aluminum and copper conductors. It is manufactured with Solid/Stranded Circular/ Shaped Aluminium / Copper Conductor. Stranding makes Cables flexible and easy to handle while shaping makes them compact.

1) Circular Conductor : With one wire in the centre conductor contains 6, 12, 18, 24, 30... wire layers in either unilay or opposite helical directions. The conductor is sized up to 92% compaction.

2) Shaped Conductors : In all multi core cables from 16 Sq. mm size, conductors are "shaped". Compaction degree in multi core power cables is up to 92%.

3) Segmental Conductor :
The conductor is manufactured in equal segments and compacted, then laid together. This reduces A. C. losses in the large sized conductor, which are due to skin and proximity effects. Hyphen has special construction of conductor to suggest to its customer for meeting their specific need.
Hyphen Copper conductor cables are of the same construction that of cables with Aluminium conductor except for high tensile strength, superior conductivity, better flexibility and ease of jointing, Copper cables are used in control, instrumentation, winding, submarine, mining and ship wiring etc. etc applications.
All Conductors for Hyphen Cables are manufactured strictly in accordance with National specifications. National specifications.

Insulation for Hyphen's cables is strictly as per National and International specifications. Hyphen's cables are designed and manufactured with polymer dielectrics to bear thermal and thermo mechanical stresses safely at continuous normal and short circuit temperature conditions. Hyphen cables are available with both thermoplastic & thermo setting insulations.

- PVC Cables     Thermoplastic dielectric
- XLPE Cables     Thermo setting dielectric

Hyphen PVC cables use PVC compounds that take care of over load and short circuit current with both coarse & fine protection systems. Hyphen cables are friendly during continuous, emergency and short circuit conditions.
XLPE cables use XLPE compound with anti oxidant stabilizers and traces of aromatic poly nuclear hydrocarbon. Thus improving electrical treeing characteristics and mechanical strength of insulation.

Though there is no change in basic design of Hyphen cables yet the latest manufacturing process gives improved reliability and compactness to cables. The relative thermal expansion during short circuit between dielectric and conductor is therefore limited to minimum both in PVC & XLPE, thus limiting displacement of cores in cables during short circuit. Insulation for Hyphen Cables are strictly manufactured and applied over conductor in accordance with National and International specifications: National Specification IS : 5831/ IS : 7098 International Specification BS : 6746/ BS :5467/ IEC : 60502

XLPE Cables with rated voltage over 3300V shall be provided with conductor and insulation screening as follows :

Conductor : Conductor shall be screened with extruded Screen : Semiconducting compound as per is :7098 Part 2 Insulation : Insulation screening shall consist of non-metallic Screen : Part in combination with metallic part. Non metallic part shall consist of either semi conducting compound tape applied helically or extruded layer of semi conducting compound, applied directly over insulation. Over this, metallic part (copper tape) shall be applied helically with overlap as per IS: 7098 part 2. To avoid the cavities and voids formation in dielectric particularly on bending operation of cable, perfect bonding of insulation and screening is required. To ensure this Hyphen applying conductor screen, insulation and insulation screen (non-metallic part) in one operation through triple extrusion.

Cores are tested on line during production both for physical and electrical characteristics. Control is observed within tight tolerance limits for dimensions in case of PVC/XLPE insulation. For multi core cables cores are laid up on our latest laying up machine equipped with sector correction equipment. In case of XLPE insulated cores the same are cured so as to impart the requisite characteristics both electrical and mechanical and then are laid up

Laid up cables are provided with inner sheath with high quality of PVC which acts as bedding for steel wire / strip armoring. Wherever required, filler cords are provided to maintain the circularity to laid up cables.

In Hyphen Cable-polymers used for inner sheath are softer than insulation or outer sheath & are compatible with temperature ratings of cables & do not have deleterious effect on any other component of cable.
Inner sheath is applied either with extrusion or by wrapping. In Hyphen Cables though the inner sheath is closely applied on the laid up cores, same can be stripped with ease without damaging insulation.

The inner sheath dimensions are maintained strictly in accordance with laid down specification. Specification For PVC Cables IS :1554 (Part-I & II)For XLPE Cables IS : 7098 (Part-I & II)

Mechanical protection to the cable is provided with armoring. Hyphen single core cables are armoured with Aluminium or Aluminium alloy wire/strips, thus avoiding magnetic hysteresis losses on A. C. System.

Multi core cables are provided with galvanized steel wire/strips.

Hyphen cables are provided with galvanized wire armoring., where cables are to run vertically and are subjected to stresses. Hyphen Mining cables are armoured with steel wire and tinned copper wires, so as to provide conductivity of armour more than 75% of main conductor of cable. Hyphen cables armour wires/strips are of low resistivity material and meet the requirements of IS:3975 . Hyphen armoured cables are with almost 95% armour coverage.

All Hyphen Cables are provided with PVC/polymer outer sheath.

In order to be identified, Hyphen Cables have their name embossed/printed/indented on outer sheath. at regular intervals on the outer sheath
of Hyphen Cables, Voltage Grade, cable size, trade name & year of manufacture are embossed, as desired. Cables are sequentially marked for
