LT - XLPE / PVC POWER AND CONTROL CABLES

HYPHEN- 1.1 KV HEAVY DUTY PVC/XLPE INSULATED, PVC SHEATHED ARMOURED AND UNARMOURED CONTROL CABLES POWER CONFORMING TO IS: 1554 (PART-1) / IS - 7098 (PART-1).

Easy Installation, as the XLPE insulated cables are lesser in weight as compared to PVC Insulated cables of same size. Higher operating temperature, current rating and overload rating makes XLPE cables more economical to Use. Higher life span and flexibility as compared to PVC cables. XLPE Insulated cables have a very high degree of resistance towards Moisture, Oil, Solvent, Acid and Alkalies compared to PVC cables which are moderately resistance to the above conditions.

XLPE Insulated cables have higher short circuit temperature that is 2500C. as compared to PVC Insulated Cables which have short circuit temperature of only 1600C. XLPE Insulated cables no side effect on health in case of a fire, however PVC cables are Carcinogenic in nature.

Specifications

Conductor Aluminium: EC Grade Aluminium Conductor as per IS: 8130-1984 Flexibility Class 1 and 2.
Copper: Electrolyic Grade Copper Conductor as per IS: 8130 -1984 Flexibility Class 1 and 2.
Insulation PVC Type A of IS: 5831-1984 for maximum conductor temperature 700C
PVC Type C of IS: 5831-1984 for maximum conductor temperature 850C
XLPE - (Cross linked polyethylene) compound of IS-7098-1988 for Maximum conductor Temperature 900C
CuringIn Caseof XLPE The insulated cores are cured in hot water chamber maintained at 900C For 4 to 6 hrs depending upon the thickness of insulation.

Tolerance on Thickness of Insulation The smallest of the measured values of thickness of insulation shall not fall below the nominal valued specified in the relevant tables by more than (0.1 mm + 0.1 t1). Where t1 = Nominal Thickness of Insulation in mm.

1. Core Cable Red, Yellow, Blue, Black, Grey, Green, White or any colour as per customer Requirement.
2. Cable Red & Black
3. Core Cable Red, Yellow & Blue
3. Core Cable Red, Yellow, Blue & Black
5. Core Cable Red, Yellow, Blue, Black & Grey
6. Core & Above
Two adjacent cores (counting & direction core) in each layer Blue and Yellow, remaining cores Grey (or) The same sequence as above alongwith indelible printing of core number or All cores same coloured with number printing on the cores at regular interval.
Laying -up The cores are laid up with a suitable right hand lay.
Inner Sheath
PVC Type ST-1 of IS: 5831-1984 for maximum conductor temperature 700C.PVC Type ST-2 of IS: 5831-1984 for maximum conductor temperature 850C.(For XLPE Cables ST-2 Only)
Application The laid up cores shall be provided with inner sheath applied either by Extrusion or by tape wrapping, as per specification requirement.

For Unarmoured single core cables no inner sheath be provided. For Unarmoured multicore cables the inner sheath may be provided in single extrusion alongwith the outer sheath. However the minimum thickness of inner sheath shall be added to the thickness of outer sheath.

Unarmoured Cables The average thickness of outer sheath of Unarmoured cables shall not be less than the nominal value specified. The
smallest of the measured values shall not be less than 0.2mm + 0.2 ts.
Armoured Cables The minimum thickness of PVC outer sheath of armoured cables shall Not fall below the nominal value (ts) specified
more than 0.2 mm+0.2ts.
Colour of Outer Sheath Colour of outer sheath shall be black or any other colour as agreed to between the purchase and the supplier.
